Space: What's out there II
Continued from here.
It would appear so, as his opinion of whether we should make contact with any alien life forms we discover in the future has suddenly hardened. According to a new documentary series he has made for the Discovery Channel : "If aliens visit us, the outcome would be much as when Columbus landed in America, which didn't turn out well for the Native Americans."
Hawking believes we would be well-advised to keep the volume down on our intergalactic chatter and do all we can to prevent any "nomadic" aliens moseying our way to take a look-see. Should they find us here tucked away in the inner reaches of the solar system, chances are they'd zap us all and pillage any resources they could get their hands on. Our own history, says Hawking, proves that first encounters very rarely begin: "Do take a seat. I'll pop the kettle on. Milk? Sugar?"
"Such advanced aliens would perhaps become nomads, looking to conquer and colonise whatever planets they can reach," says the theoretical physicist in Into the Universe with Stephen Hawking. "To my mathematical brain, the numbers alone make thinking about aliens perfectly rational. The real challenge is to work out what aliens might actually be like."

NASA has reported a major delay in what was to be its last shuttle mission - a trip by Endeavour to deliver a particle detector to the International Space Station.
Science teams announced earlier this week they want to replace the magnet in the Alpha Magnetic Spectrometer that was to be transported to the station in late July so it can operate longer in orbit.

Gerrard Winstanley once talked to the King of England about the oppressive living conditions of the peasants while the monarchy spent money with wild abandon on warring with France and Spain. Winstanley said to the king that if living conditions for the peasants didn't improve that they would not object to occupation by a foreign military.
Could it be that the billionaire ruling class running things would not want their power and sense of supremacy usurping by strangers with a different point of view of things in general? Are the creme de la creme afraid to admit to the fact that they are not really masters of the universe? Our supreme beings on earth are living pretty well as things stand now.

THANK GOD THAT HAPPENED. I am planning a road trip with another space geek friend of mine, hopefully we'll be able to see the last STS mission launch!
As a scientist, he should know better: Any interstellar civilization would possess such technologies that the meager resources of Earth would be unneeded. If you can travel faster than the speed of light, you can manifest what is needed. Period. Moreover, if they were hostile, since ETs are already visiting Earth (see www.DisclosureProject.org) this would have been made crystal clear when we detonated the first atomic weapon in 1945. To date, no place on Earth has been invaded or attacked or colonized.
And if they can travel at the speed of light, why not the speed of thought, too? Freeman Dyson wrote that if the Kardashev scale of advanced civilizations based on increasing energy consumption is true, then we will become type I in a hundred years or so. After that type II is only 3200 years or so away given a modest growth rate of one percent a year. Type III civilizations would be out of this world and comparable to Star Trek sci-fi, or is it Star Wars level of technical capabilities? Kardashev estimated type III status might only represent 5800 years of technological advancement after that. Type IIIs have the technical capability to harness the energy of galaxy, as incredible as that sounds. According to Michio Kaku, evolution and technological advancement are only a matter of time.
I tend to agree with Stephen Greer. If they are that advanced, then they likely need nothing from us. Carl Sagan once described the difference between us and a theoretical civilization one million years more technologically advanced as how we perceive macaque monkeys. What do we have in common really? What can we learn from macaques other than to study them and their environment? Scientists suggest that the rest of us non-scientists simply follow the rule of live and let live. Do no harm.
Perhaps discovery will happen something like this (YouTube)

The rhesus monkey has been widely used in medical and other scientific experiments; the Rh blood factor, found in humans as well as monkeys, is named for it.

Alright? So they come and take a few dna samples, figure out that we're not remotely related. Or maybe we are distantly related through some kind of panspermian exogenesis connection. Theoretical ET of a type III or even IV technological advancement has not only solved the issue of travel at speed of light and energy requirements, perhaps they've also found the solution to their own longevity through genetic engineering. Our own scientists are saying it should be possible for us some day in the future. This period we are living in now will someday be referred to as pre-genetic engineering or Pre-GE, a kind of technological dark age compared with medical science of the future.

This is James Trefil's rundown of The Little Book of String Theory by Steven Gubser
Some background: In the 19th century we learned that all matter is made from atoms. In the 20th century we learned that the particles in the nuclei of those atoms -- mistakenly called "elementary particles" at first -- are made up of things more elementary still, called quarks. String theory is an attempt to peel the next layer from this onion. In this picture, the fundamental objects that make up all matter are microscopic vibrating strings. The strings make the quarks that make the particles that make . . . . You get the picture.
Sounds simple enough, but Gubser hasn't gotten more than three pages into his book before he drops the other shoe. Turns out that, depending on which version of the theory you want to use, these strings vibrate in either 10 or 26 dimensions. From there on we're off and running into what has to be the most bizarre and abstract area of modern science, the place where the frontier becomes really wild.
Got it? Good. Because I don't.
Hawking Warning About Bad Aliens Prompts Defense by Their Biggest Canadian Fan
http://www.winnipegfreepress.com/breakingnews/hawking-warning-about-bad-...
"Former federal defence minister Paul Hellyer, 86, believes not only that aliens have visited Earth but also that they have contributed greatly to human advances.."
What if? What if this short sci-fi story really happened? Apparently X-file types and some ufologists believe it was an historical event that was kept under wraps. They refer to the 1950's Hollywood version though, and it was entitled, The Day the Earth Stood Still. Imagine, as the last comment in the wiki articles states, that Klaatu is not who he appears to be, and neither is Gnut/Gort. Shocking!
Stephen Hawking eh? Looking for aliens in all the wrong places Are they among us? Have David Fairn and Paul Davies been assmililated already?
It's one of the "things" that bothers me about our own evolution. We didn't start out at the top of the food chain. We had few natural characteristics that made us fiersome predators. No sharp talons, like many dinosaurs had. We had no razor sharp fangs for tearing flesh and crunching bones, like big cats or whatever it was that lived to eventually produce hyenas. We couldn't run very fast to chase down dinner or posesss strength enough to take down very many prey as big or bigger than ourselves. The odds that we would evolve to become leaders of the pack must have been somewhat remote.
I wonder what other advanced and "highly successful" life forms might be like? Would some alien species be capable of taking over our governments without a power struggle? Would they thrive under increased atmospheric conditions of CO2 and GHGs closer to that of global warming ten or 20 years from now? And, I've always wondered where in the heck sci-fi writers get their material from? I've often thought that they must be on something.

Intelligent Life in the Universe? While Drake's equation is a good basis for systematic investigations of signals from extraterrestrial intelligences, I care little about the admittedly scarce possibility that we ever receive positive news from our SETI searches. I care more about the fact that, if we consider the whole universe instead than restricting to our small galaxy, and if we omit to require that other civilizations exist at present (whatever this means over billion-light-year distance scales), the probability becomes a certainty.Tommaso Dorigo
***I was over at Tommaso Dorigo's Blog, Quantum Diaries Survivor" reading his take on Extraterrestrials: A Dime A Dozen and the opening with Stephen Hawkings Lecture. I cut out the section of my interest as well to see what Dr. Hawking was talking about, besides reading Tommaso's take.
Qualitatively, I have come to realize, given the framework for consideration of such possibilities, these equations mean an inductive/deductive self evident constraint how are we ever to consider the possibility( You have to give yourself permission to entertain).
I mean can we ever know the framework of that Extraterrestrial Intelligence given the parameters for our own belief structures? We do not even know what is possible "not having the framework" to properly question how this can be so?
So what I found in Dr.Hawkings lecture was the generalities of consensus across the industry of science and no new ways in which to possibly perceive the" right questions concerning the framework for possible new intelligences" that we would perceive as Extraterrestrials.
...........DR. HAWKING: What will we find when we go into space? Is there alien life out there, or are we alone in the universe?NASA's 50th Anniversary Lecture By Professor Stephen Hawking
We believe that life arose spontaneously on the Earth. So it must be possible for life to appear on othersuitable planets, of which there seem to be a large number in the galaxy.
But we don't know how life first appeared. The probability of something as complicated as a DNA molecule being formed by random collisions of atoms in ocean is incredibly small. However, there might have been some simpler macro molecule which can build up the DNA or some other macro molecule capable of reproducing itself. Still, even if the probability of life appearing on a suitable planet is very small, since the universe is infinite, life would have appeared somewhere. If the probability is very low, the distance between two independent occurrences of life would be very large.
However, there is a possibility known as panspermia that life could spread from planet to planet or from stellar system to stellar system carried on meteors. We know that Earth has been hit by meteors that came from Mars, and others may have come from further afield. We have no evidence that any meteors carried life, but it remains a possibility.
An important feature of life spread by panspermia is that it would have the same basis which would be DNA for life in the neighborhood of the Earth.On the other hand, an independent occurrence of life would be extremely unlikely to be DNA based. So watch out if you meet an alien. You could be infected with a disease against which you have no resistance.
One piece of observational evidence on the probability of life appearing is that we have fossils from 3.5 billion years ago. The Earth was formed 4.6 billion years ago and was probably too hot for about the first half billion years. So life appeared on Earth within half-a-billion years of it being possible, which is short compared to the 10-billion-year lifetime of an Earth-like planet.
This would suggest either panspermia or that the probability of life appearing independently is reasonably high. If it was very low, one would have expected it to take most of the 10 billion years available. If it is panspermia, any life in the solar system or in nearby stellar systems will also be DNA based.
While there may be primitive life in another region of the galaxy, there don't seem to be any advanced intelligent beings. We don't appear to have been visited by aliens. I am discounting reports of UFOs. Why would they appear only to cranks and weirdos?
[Laughter.]
DR. HAWKING: If there is a government conspiracy to suppress the reports and keep for itself the scientific knowledge the aliens bring, it seems to have been a singularly ineffective policy so far.
Furthermore, despite an extensive search by the SETI project, we haven't heard any alien television quiz shows. This probably indicates that there are no alien civilizations at our stage of development within the radius of a few hundred lightyears. Issuing an insurance policy against abduction by aliens seems a pretty safe bet.
Why haven't we heard from anyone out there? One view is expressed in this Calvin cartoon. The caption reads: "Sometimes I think that the surest sign that intelligent life exists elsewhere in the universe is that none of it has tried to contact us."
More seriously, there could be three possible explanations of why we haven't heard from aliens. First, it may be that the probability of primitive life appearing on a suitable planet is very low.
Second, the probability of primitive life appearing may be reasonably high, but the probability of that life developing intelligence like ours may be very low. Just because evolution led to intelligence in our case, we shouldn't assume that intelligence is an inevitable consequence of Darwinian natural selection.
It is not clear that intelligence confers a long-term survival advantage. Bacteria and insects will survive quite happily even if our so-called intelligence leads us to destroy ourselves.
This is the third possibility. Life appears and in some cases develops into intelligent beings, but when it reaches a stage of sending radio signals, it will also have the technology to make nuclear bombs and other weapons of mass destruction. It will, therefore, be in danger of destroying itself before long.
Let's hope this is not the reason we have not heard from anyone. Personally, I favor the second possibility that primitive life is relatively common, but that intelligent life is very rare. Some would say it has yet to occur on Earth.
[Laughter.]
DR. HAWKING: Can we exist for a long time away from the Earth? Our experience with the ISS, the International Space Station, shows that it is possible for human beings to survive for many months away from Planet Earth. However, the zero gravity aboard it causes a number of undesirable physiological changes and weakening of the bones, as well as creating practical problems with liquids, et cetera.
One would, therefore, want any long-term base for human beings to be on a planet or moon. By digging into the surface, one would get thermal insulation and protection from meteors and cosmic rays. The planet or moon could also serve as a source of the raw materials that would be needed if the extraterrestrial community was to be self-sustaining independently of Earth.
What are the possible sites of a human colony in the solar system? The most obvious is the Moon. It is close by and relatively easy to reach. We have already landed on it and driven across it in a buggy.
On the other hand, the Moon is small and without atmosphere or a magnetic field to deflect the solar radiation particles, like on Earth. There is no liquid water, but there may be ice in the craters at the north and south poles. A colony on the Moon could use this as a source of oxygen with power provided by nuclear energy or solar panels. The Moon could be a base for travel to the rest of the solar system.
Mars is the obvious next target. It is half as far, again, as the Earth from the Sun and so receives half the warmth. It once had a magnetic field, but it decayed 4 billion years ago, leaving Mars without protection from solar radiation. It stripped Mars of most of its atmosphere, leaving it with only 1 percent of the pressure of the Earth's atmosphere.
However, the pressure must have been higher in the past because we see what appear to be runoff channels and dried-up lakes. Liquid water cannot exist on Mars now.
It would vaporize in the near-vacuum. This suggests that Mars had a warm wet period during which life might have appeared either spontaneously or through panspermia. There is no sign of life on Mars now, but if we found evidence that life
once existed, it would indicate that the probability of life developing on a suitable planet was fairly high.
NASA has sent a large number of spacecraft to Mars, starting with Mariner 4 in 1964. It has surveyed the planet with a number of orbiters, the latest being the Mars Reconnaissance Orbiter. These orbiters have revealed deep gullies and the highest mountains in the solar system.
NASA has also landed a number of probes on the surface of Mars, most recently the two Mars Rovers. These have sent back pictures of a dry desert landscape. However, there is a large quantity of water in the form of ice in the polar regions. A colony on Mars could use this as a source of oxygen.
There has been volcanic activity on Mars. This would have brought minerals and metals to the surface which a colony could use.
The Moon and Mars are the most suitable sites for space colonies in the solar system. Mercury and Venus are too hot, while Jupiter and Saturn are gas giants with no solid surface.
The moons of Mars are very small and have no advantages over Mars itself.
Some of the moons of Jupiter and Saturn might be possible. In particular, Titan, a moon of Saturn, is larger and more massive than other moons and has a dense atmosphere.
The Cassini-Huygens Mission of NASA and ESA has landed a probe on Titan which has sent back pictures of the surface. However, it is very cold, being so far from the sun, and I wouldn't fancy living next to a lake of liquid methane.
What about beyond the solar system? Our observations indicate that a significant fraction of stars have planets around them. So far, we can detect only giant planets like Jupiter and Saturn, but it is reasonable to assume that they will be accompanied by smaller Earth-like planets. Some of these will lay in the [inaudible] zone where the distance from the stars is the right range for liquid water to exist on their surface.
There are around a thousand stars within 30 lightyears of Earth. If 1 percent of each had Earth-size planets in the [inaudible] zone, we would have 10 candidate new worlds. We can revisit it with current technology, but we should make interstellar a long-term aim. By long term, I mean over the next 200 to 500 years. The human race has existed as a separate species for about 2 million years.
Civilization began about 10,000 years ago, and the rate of development has been steadily increasing.
If the human race is to continue for another million years, we will have to boldly go where no one has gone before.Solar Dynamics Observatory
SpaceCraft
*** April 21, 2010: Warning, the images you are about to see could take your breath away.At a press conference today in Washington DC, researchers unveiled "First Light" images from NASA's Solar Dynamics Observatory, a space telescope designed to study the sun.
"SDO is working beautifully," reports project scientist Dean Pesnell of the Goddard Space Flight Center. "This is even better than we could have dreamed."
Launched on February 11th from Cape Canaveral, the observatory has spent the past two months moving into a geosynchronous orbit and activating its instruments. As soon as SDO's telescope doors opened, the spacecraft began beaming back scenes so beautiful and puzzlingly complex that even seasoned observers were stunned.

***NASA's New Eye on the Sun Delivers Stunning First Images 04.21.10
View related briefing materials here.
NASA's recently launched Solar Dynamics Observatory, or SDO, is returning early images that confirm an unprecedented new capability for scientists to better understand our sun’s dynamic processes. These solar activities affect everything on Earth.
Some of the images from the spacecraft show never-before-seen detail of material streaming outward and away from sunspots. Others show extreme close-ups of activity on the sun’s surface. The spacecraft also has made the first high-resolution measurements of solar flares in a broad range of extreme ultraviolet wavelengths.
"These initial images show a dynamic sun that I had never seen in more than 40 years of solar research,” said Richard Fisher, director of the Heliophysics Division at NASA Headquarters in Washington. "SDO will change our understanding of the sun and its processes, which affect our lives and society. This mission will have a huge impact on science, similar to the impact of the Hubble Space Telescope on modern astrophysics.”

If weirdos include Apollo astronauts, airline pilots, RCMP officers, and US presidents, then we're in trouble for sure.
I agree with Ed Mitchell on this question. The coverup since 1947 has been largely ineffective. Information about UFOs has been leaked to the public for decades. It's not a secret anymore.
But Dr Kaku likens SETI's search of radio spectrum at or near the frequencies of hydrogen to a drunk who's lost his keys at night in the street. He chooses to look only near the lamp post where it's illuminated. The lost keys could be anywhere else in the darkened street.
And we've been a technically advanced civilization for a few hundred years. Broadcast radio and TV and spaceships have been our advanced technologies for merely a few decades - a very tiny slice of time in the larger unversal scheme of things. And now the ten thousand watt blowtorch radio stations and analog TV broadcasts are giving way to digital over analog, fibre and cable transmissions. At some point when over the air TV and radio broadcasts are fully digitized over fiber trunklines, the noise emitted by our own doing will have mostly stopped. That leaves a very tiny time window of wide broadcast era for aliens to have tuned in to planet earth. Our planet will become relatively quiet before long.
I think Arthur Clarke received better scientific advice on his 2001: A Space Odyssey, sci-fi novel. Scientists suggested to Clarke that advanced civilizations probably wouldnt be listening to radio waves from space for a superimposed message from beyond the solar system. They would likely send out self-replicating "von Neumann probes", and perhaps even construct monoliths on planetary moons for perhaps a type I or II civilization to discover. Upon discovery of the monolith, the type III or IV civilization(according to Kardashev's and Dyson's estimates) would then become aware of the newly evolving civilization from afar, and perhaps even have something important to say to them at that point in time.
Carl Sagan said that an advanced civilization one-million years old would be as incomprehensible to us as we are comparable to macaque monkeys. What would they have to say to us at this point in human evolution?
Is that not a sobering thought ? To me, that is both awesome and saddening. As far as awe is concerned, of course there is no need to explain it. But there is sadness too: for imagine the incredible, unfathomable number of things that we will never be able to know, constrained in our tiny planet, during our insignificant lives. Masterpieces, inventions, acts of bravery, adventures. But also wars, atrocities, catastrophes. The history of the universe will never be written - but it would be quite a read, I am sure.Tommaso Dorigo
Hi Fidel, My point, given the parameters of any way in which to engage such a discussion may not be relevant to what we can conclude having meet a Extraterrestrial Intelligence. Tommaso used the Drake Equation and expanded the probability by "increasing the parameters?"
Also given the parameters of what we know how can we even formulate the right question about it's existence. Any attempt to do so is "a guess by best estimates" so if one wanted to add their take, it is just as easily feasible to think about their statements? What do you think?
I mean we want to be responsible citizens about the context of the question, then how in such responsibility can this question be framed? I believe Drake thought of it in this way.
So I will give you a fictional scenario to contemplate. A different take on Cleopatra?
James Cameron's AVATAR
This post will indeed seem quite odd. But as I told Phil I wanted to explain a principal behind all the language I used here as if it would appear to another if we assume another perspective.
James Cameron's AVATAR
Now we know how some of us who go the the extreme in science like to think the basis of what we explain as a fictional story is correlative in the context of what we relay, knows there is science that is factually represented to unfold.
Temple of Hathor,DenderaSo I have to present something in story like form as was presented in the latest movie Avatar. This is to spark a historical look back in our own history, so as to know that we existed in cohabitation with beings that hold the basis of a thought pattern, that is the basis of this blog. See how quickly one can move?
Temple of Hathor, Dendera
(click on image and take note of columns)
You have to look very carefully now throughout these artifacts in architectural design as to understand something quite unique about the the times and what some of these statue faces actually represented. See how these images are denoted amongst the Gods and Goddesses to understand that images reveal something unique about what the Sun and Moon mean in relation to each other and who was the Mother of them.
.....................
I highlighted a statement about the basis of the blog I write.
Typing in "sound" in search feature might help one to get an idea on how it is I see science in concert with. The way in which taking such a basis, as to see in another analogistic way. Gives one a way in which to see, given a different parameter.
It may help one see the cosmos in the way we do our science. Questions about how we can see gravity. Enclosing a parameter about which, the whole process we are involved is exemplified in such a way as to think about the very question of our articulations. The topic of Intelligent extraterrestrial can mean in that context?
Yes, a grand total of two technically advanced civilizations in the Milky Way is not very impressive and would seem highly improbable that the only other one would still exist in order for us to hook up with them at some point. And that's if they haven't destroyed themselves or are even paralleling our own rate of progress. It might take a while to locate them.
And Carl Sagan was a little more optimistic with his example of N~10. But Sagan also said about Drake's parameters, what if only one percent of civilizations were to survive their own technological adolescence? He said that would make parameter F sub big L not one-one-huundred millionth but simply 1/100. N then becomes approximately millions, if ALL advancing civilizations DO NOT ALWAYS destroy themselves. Sagan's seems like a reasonably logical statement to make, and I tend to favor it over that of Fermi's. Drake's equation can be thought of as an English sentence and the verb being equals to. And the sentence can be constructed in many, many different ways. And if I was a gambler and the wager could be collected on, I would bet high stakes that we are not alone in this galaxy.
Very thoughtful and interesting question, and you know that I don't have a proper answer. But I can imagine that perhaps there are a number of civilizations that have been in communication with each other for some time. Perhaps it's a clique of advanced civilizations that only have interesting things to ask of and answer to one another. Perhaps they perceive what we have to say as baby talk, or perhaps they even think of our language and what we express with it as akin to a macaque with outstretched paws demanding a grape or banana or something. Perhaps it's as the more democratic of us here on earth think of third world developing countries. Malalai Joya has said to Canadians and Americans several times that we cannot donate democracy to the people of her country. Perhaps advanced civilizations feel similarly in that we must either tread water by ourselves or make way for another species here on earth to take over the path of evolution where we might fail some day. I don't know and truly wish that I could. Perhaps they feel we are a dead end in the Darwinian scheme of things and simply refuse to invest anything in communicating with us. Would we invite monkeys into our homes and places of work? Sign out a macaque from the local petting zoo for an hour or so on Fridays? Perhaps it would be a pointless exercise in zoological study for them. Perhaps they are able to appreciate mankind from afar and in their own way. Perhaps the crop circles, the ancient statues, massive stone structures and aerial sightings are to keep us guessing and wondering about the possibilities.
Hi Fidel,
I was taken back by that statement too when you pointed this out in reference to Stephen's comments. Knowing the matter of fact of and all that was supplied as to the reasoning, was information, that had been around for a while and really had nothing new to offer except the same ole argumentative debates about credibility. Not that we dispense with it , but that we take seriously the efforts in order to question the existence of.
I mean let's say that if that extraterrestrial intelligence did not want you to identify the encounter, how would they mask it? In our everyday psychological make up, maybe, to have it appear that we were dreaming, and they supplied the "facets of imagery" to mask the experience? The face of the extraterrestrial while it's eyes may appear yellow may refer the experience to have an image of a bird(an owl let's say) superimposed over that experience to have the physical interaction falsified.
The extraterrestrials would have to know the general consensus of experience can be clouded by fact and not unsupportable facts of existence?
This bird
SEE:Hinterland Who's Who
So you see, this is one way in which to approach the question, that may not have been looked at before.
Avatars, are a subject within themself. Raises question about the "inhabitant of the body we now exist in" and how such occupants can converse given that they are from different locations of the universe? You see? Let's say the extraterrestrials wanted to make a hybrid human form from the alien form that could pass scrutiny and do their work as "busy worker bees?"
A lot of genetic engineering and false starts that take a long time to perfect. They have this offspring culture their building because of all the mistakes and have to form a new colony of the rejects?:) Maybe they have an extermination project to those that do not meet the human standard?
IN no way have I supplied an answer to the question about the existence of , only that given the understanding that such parameters of thinking had are limited in our discussion , and referred back to some scientific understanding, how could we really know , if you did not push the boundaries of thinking?
The extraterrestrials would have to know the general consensus of experience can be clouded by fact and not unsupportable facts of existence?
Yes, and I tend to believe that it's possible they may come here not from tens of millions of light years distant galaxies, but possibly from other dimensions or parallel universes. Dr Michio Kaku says that ten years ago, such theories of other universes were scoffed at by mainstream scientists but no so today. Kaku remembers visiting a Japanese tea garden in San Jose when he was a boy. He remembers watching fish in a pond and thinking they only knew a two dimensional world of side to side, up and down within limits, and that the fish knew nothing of an entire world immediately above the level of the water. Some scientists believe today that we are the fish in that scenario, and that our universe is an inflationary bubble existing in what could be an ocean of universes and expanding all the time. I think that nay sayers tend to think of other possible civilizations as being no more than one or two hundred years more technically advanced than us. We find it difficult to imagine civilizations that are thousands and even millions of years more advanced. Perhaps they exist and have developed the technical means of a type III or even IV civilization according to Kardashev's theoretical civilizations. Perhaps they are able to leap bounds of distance, time, and even travel through multiverses and megaverses of reality, like the snowy owl is able to deceive competitors and other animals in nature. Perhaps we are the field mice unaware of our own surroundings as youve suggested. Thanks Spectrum. Really good post.
Understanding other worlds came naturally to him. Perhaps it was an inevitable consequence of being the child of Japanese Americans. His parents, though born in California, spent World War II behind barbed wire, guarded by people with machine guns: incarcerated by their own country as enemy aliens. Afterwards his father worked as a gardener, his mother a maid: two of the few jobs that were available to Japanese Americans. Kaku grew up poor, but one of the family treats was to visit the Japanese Tea Garden in San Francisco's Golden Gate Park. It turned out to be the place of a childhood epiphany. Wondering in the way that only a child does, Kaku looked at the carp swimming in a weedy pond and imagined how they would not be able to conceive of other worlds. "A carp engineer would believe that was all there is; but a carp physicist would see the ripples on the surface and start thinking about unseen dimensions," Kaku told me, laying the first of many lashes on his token engineer.
Perspective of the Theoretical Scientist
A look at the higher dimensions By Michio Kaku
"Why must art be clinically “realistic?” This Cubist “revolt against perspective” seized the fourth dimension because it touched the third dimension from all possible perspectives. Simply put, Cubist art embraced the fourth dimension. Picasso's paintings are a splendid example, showing a clear rejection of three dimensional perspective, with women's faces viewed simultaneously from several angles. Instead of a single point-of-view, Picasso's paintings show multiple perspectives, as if they were painted by a being from the fourth dimension, able to see all perspectives simultaneously. As art historian Linda Henderson has written, “the fourth dimension and non-Euclidean geometry emerge as among the most important themes unifying much of modern art and theory."

The appearance of figures in cubist art --- which are often viewed from several direction simultaneously --- has been linked to ideas concerning extra dimensions:* H. S. M. Coxeter, Regular Polytopes (New York: Dover, 1973) is the great classic text by a great creative force in this beautiful area of geometry (A polytope is an n-dimensional analog of a polygon or polyhedron. Chapter V of this book is entitled 'The Kaleidoscope'....)"
The other reason is just that the complete mapping of E8 is the largest mathematical structure ever mapped out in full detail by human beings. It takes 60 gigabytes to store the map of E8. If you were to write it out on paper in 6-point print (that's really small print), you'd need a piece of paper bigger than the island of Manhattan. This thing is huge.
So if ET does exist near other star systems, say, zeta reticula 1 and 2, and governments here are aware of them, then why would the feds want to keep it a secret? Because we've been told by skeptics that it is impossible for governments to keep secrets, and therefore, UFOs must not be real. At least, this is the line of reasoning they use, And they can typically be very clever and educated people who say these things.
Why would religious fanatics like Falwell and Robertson declare that UFOs are the work of satan? As far as I can tell, our governments and the people who influence them want us to believe that UFOs are either a hoax or the work of the devil. Someone's lying.

I finally broke and got a credit card. The other day I was looking at the MUFON website and almost became a member. There, that is my terrible admission for the month.
And Fidel, I agree with you 100%. Local news should carry UFO reports and blurry videos all the time! I have been crushed by the lack of great paranormal things on the market lately. No more good tabloids at the super market...without them I have no idea who the Loch Ness monster is dating (is it Ogopogo or the Shagharbor thing?). Local news should pick up the slack and give me the ultimate in poor journalism. Sensationalist fluff pieces about UFOs and Big Foot sightings in the GTA area with blurry videos and horridly great interviews with MUFON field reporters, UFOlogists and the like.
As for the alien threat? I for one welcome our robot overlords.
I agree with David Brin when he says that scientists should be consulted, and that this topic needs discussing at a high levels. Five years ago, we knew of no planets outside our solar system. Today about 500 have been identified. SETI has scanned the heck out of earth's neighbors within 100 light years. The galaxy though is a 100,000 light years across. They need to search elsewhere and using a lot more radio telescopes.
....Five years ago, we knew of no planets outside our solar system....
Just to nitpick: I believe the first exosolar planets were confirmed in 1992, and we had a fairly good idea that they were since the latter part of the nineteenth century.
http://www.nature.com/nature/journal/v355/n6356/abs/355145a0.html
Well that's a good nit to pick.
I'm guessing that with solar orbits as short and as near the central star as they are, they will be hot gaseous masses as opposed to planets like this one.
I was reading something on Canadian physicist Stanton Friedman's website. Friedman went to school with Carl Sagan and was friends with him. Friedman says of the Drake equation that the parameters should take into consideration the number of stars created per year. There are no parameters for possible explorations and colonizations by any number of advancing civilizations over time.
And there is no factoring for lifetime of a civilization. We are but one example among 100 billion stars in this galaxy alone. It's not a very accurate sample because: one, we have no idea how long our own civilization will survive, and two, we don't know how long it's possible for other civilizations to have survived thus far.
Zeta reticula 1&2, according to Friedman, are "just down the road" relatively speaking at 39 light years. And they are one-billion years older than our sun. Very interesting star system. And Friedman sounds a lot like Dr Kaku when it comes to naysayers suggesting that communicating and even travelling from there to here is wrought with physical impossibilities. Why would they even try to contact us - why aim a signal in our direction? Would they say, Here we are. What can we do for you, earthlings? It doesn't make sense. And receiving a message back 500 years later would make even less sense.
Friedman suggests, as Kaku does, that advanced space travel technology is only a matter of time. Today we are able to fly from east to west coast in a matter of hours. Before passenger planes, people would have thought that intercontinental travel in a matter of hours was an absurd idea. And as Friedman says, there is work being down outside of academia all the time. Friedman himself did work on advanced space propulsion systems and nuclear technologies that just weren't discussed in academic circles for many years until now.
Fidel, I thought you might be interested on how some see space travel and how some of the factors of satellite travel have to take in consideration of Lagrangian.Quote: LTool
A "freeway" through the solar system resembling a vast array of virtual winding tunnels and conduits around the Sun and planets, as envisioned by an engineer at NASA's Jet Propulsion Laboratory (JPL), Pasadena, Calif., can slash the amount of fuel needed for future space missions. Called the Interplanetary Superhighway, the system was conceived by Martin Lo, whose software was used to help design the flight path for NASA's Genesis mission, which is currently using this "freeway in space" on its mission to collect solar wind particles for return to Earth. Most missions are designed to take advantage of the way gravity pulls on a spacecraft when it swings by a body such as a planet or moon. Lo's concept takes advantage of another factor, the Sun's pull on the planets or a planet's pull on its nearby moons. Forces from many directions nearly cancel each other out, leaving paths through the gravity fields in which spacecraft can travel. Each planet and moon has five locations in space called Lagrange points, where one body's gravity balances another's. Spacecraft can orbit there while burning very little fuel. To find the Interplanetary Superhighway, Lo mapped some possible flight paths among the Lagrange points, varying the distance the spacecraft would go and how fast or slow it would travel. Like threads twisted together to form a rope, the possible flight paths formed tubes in space. Lo plans to map out these tubes for the whole solar system. Lo's research is based on theoretical work begun in the late nineteenth century by the French mathematician Henri Poincare. In 1978, NASA's International Sun-Earth Explorer 3 was the first mission to use low energy orbits around a Lagrange point. Later, using low energy paths between Earth and the Moon, controllers at NASA's Goddard Space Flight Center, Greenbelt, Md., sent the spacecraft to the first encounter with a comet, Comet Giacobini-Zinner, in 1985. In 1991, another method of analyzing low energy orbits was used by engineers from JPL and the Japanese Space Agency to enable the Japanese Hiten mission to reach the Moon. Inspired by this pioneering work and research conducted by scientists at the University of Barcelona, Lo conceived the theory of the Interplanetary Superhighway. Lo and his colleagues have turned the underlying mathematics of the Interplanetary Superhighway into a tool for mission design called "LTool," using models and algorithms developed at Purdue University, West Lafayette, Ind. The new LTool was used by JPL engineers to redesign the flight path for the Genesis mission to adapt to a change in launch dates. Genesis launched in August 2001. The flight path was designed for the spacecraft to leave Earth and travel to orbit the Lagrange point. After five loops around this Lagrange point, the spacecraft will fall out of orbit without any maneuvers and then pass by Earth to a Lagrange point on the opposite side of the planet. Finally, it will return to Earth's upper atmosphere to drop off its samples of solar wind in the Utah desert. "Genesis wouldn't need to use any fuel at all in a perfect world," Lo said. "But since we can't control the many variables that occur throughout the mission, we have to make some corrections as Genesis completes its loops around a Lagrange point of Earth. The savings on the fuel translates into a better and cheaper mission." Lo added, "This concept does not guarantee easy access to every part of the solar system. However, I can envision a place where we might construct and service science platforms around one of the Moon's Lagrange points. Since Lagrange points are landmarks for the Interplanetary Superhighway, we might be able to shunt spacecraft to and from such platforms." A team at NASA's Johnson Space Center, Houston, working with the NASA Exploration Team, proposes to someday use the Interplanetary Superhighway for future human space missions. "Lo's work has led to breakthroughs in simplifying mission concepts for human and robotic exploration beyond low-Earth orbit," said Doug Cooke, manager of Johnson's Advanced Development Office. "These simplifications result in fewer space vehicles needed for a broad range of mission options." The work on the Interplanetary Superhighway for space mission design was nominated for a Discover Innovation Award by Discover magazine editors and an outside panel of experts. JPL is managed for NASA by the California Institute of Technology, Pasadena. For more information on the Genesis mission, visit the Internet at: http://www.genesismission.org

This stylized depiction of the ITN is designed to show its (often convoluted) path through the solar system. The green ribbon represents one path from among the many that are mathematically possible along the surface of the darker green bounding tube. Locations where the ribbon changes direction abruptly represent trajectory changes at Lagrange points, while constricted areas represent locations where objects linger in temporary orbit around a point before continuing on
This book describes a revolutionary new approach to determining low energy routes for spacecraft and comets by exploiting regions in space where motion is very sensitive (or chaotic). It also represents an ideal introductory text to celestial mechanics, dynamical systems, and dynamical astronomy. Bringing together wide-ranging research by others with his own original work, much of it new or previously unpublished, Edward Belbruno argues that regions supporting chaotic motions, termed weak stability boundaries, can be estimated. Although controversial until quite recently, this method was in fact first applied in 1991, when Belbruno used a new route developed from this theory to get a stray Japanese satellite back on course to the moon. This application provided a major verification of his theory, representing the first application of chaos to space travel.
Since that time, the theory has been used in other space missions, and NASA is implementing new applications under Belbruno's direction. The use of invariant manifolds to find low energy orbits is another method here addressed. Recent work on estimating weak stability boundaries and related regions has also given mathematical insight into chaotic motion in the three-body problem. Belbruno further considers different capture and escape mechanisms, and resonance transitions.
Providing a rigorous theoretical framework that incorporates both recent developments such as Aubrey-Mather theory and established fundamentals like Kolmogorov-Arnold-Moser theory, this book represents an indispensable resource for graduate students and researchers in the disciplines concerned as well as practitioners in fields such as aerospace engineering.

I had some conversation with Paul Karl Hoiland according to the dates and time as his interest was how one may have used scenarios to accomplish some method of application to space travel.
My Picture in Jest with some of the Journal Group
Paul Karl Hoiland - Feb 10, 2004 7:20 am In 1994 a Mexican mathematician, Miguel Alcubierre, discovered solutions to Einstein's equations which allow warps in the space-time metric to travel faster than the speed of light. But the proposal Dr. Alcubierre made was unrealistic on three basic grounds:
1.) It required a huge amount of negative energy. 2.) It displayed no casual connection of the ship with the field itself. 3.) The exotic energy states involved violated certain quantum energy conditions like the AWEC.
The ESAA group was founded with the ever present human nature of exploration in mind. The ultimate goal of the group is to physically explore the outer most human reaches, with an emphasis on intellectual exploration to achieve such goals.
ESAA was founded by Fernando Loup, Edward Halerewicz, and David Waite to begin investigations into plausible methods to probe the outer reaches of known science. Fernado Loup a mathematician by trade was interested in exploring mathematical possibilities which may allow for superluminal travel. Edward Halerewicz a beginning physics student was primarily interested in popularizing advanced physical theories to encourage "outside the box thinking." David Waite a seasoned physics student was also interested in exploring the limits of known science and kept radical proposals grounded in real world physics. These three thinkers came together and discussed a recent theory within general relativity which would allow for serious superluiminal discussions.
These discussions were opened in December 2000 to all that were interested within a yahoo discussion forum called the "Alcubierre Warp Drive" Club, named for the proposed superluimnal theory. The active members of the yahoo club then christened a name for themselves which became ESAA. The name ESAA was created by a club supporter named Simon Jenks, which is a Greek acronym for E Somino Ad Astra, or "From a Dream to the Stars." ESAA is an open and diverse group of individuals who are interested in seeking out nature's secrets to make some of mankind's most profound dreams come true.
The ESAA group consist of physicists, mathematicians, engineers, students, and layman whose members are spread throughout the globe. All members have an equal say on group developments and collectedly the group has worked on three separate modifications to "Warp Drive" theories alone. In more recent times Dr. Paul Hoiland has become a valuable member of the ESAA group. Bringing much needed experience and wisdom to the group as well as creating the Journal of Advanced Theoretical Propulsion, based on the ESAA philosophy.
ESAA History on the Warp Drive
The online discussion forum the Alcubierre Warp Drive, began as a novel experiment, where members would answer questions that interested parties had for the new science. The early discussions within the Alcubierre Warp Drive began with philosophical debates, random brain storming, and slowly evolved to include mathematical discussions. It was during this new phase where Waite joined the club discussion, and we carefully began discussing the ramifications of his proposed warp drive. Unfortunately as soon as the mathematics became the bulk of the discussion, most of the philosophical debates were lost, but at this point Fernando Loup and Edward Halerewicz began to describe the possible consequences of Waite's space-time. During the discussion of Waite's idea the club was very grateful to receive advice and guidance from the very busy but gracious Dr. Alcubierre. And it was at this point that simply entertaining the idea of a new warp drive became a much more formal process, and a new theory of its own right began to form.
The three early founders put together a paper which tried to levitate some of the problems with the "Alcubierre Warp Drive," (gr-qc/0009013) specifically reducing the amount of negative energy required within the theory. The paper was posted at the LANL ArXiv and was entitled "Reduced Total Energy Requirements for a Modified Alcubierre Warp Drive Space-time" (gr-qc/0107097). The paper also was not accepted for publication in established journals do to the inexperience of the authors in writing for academia. Also the paper was later found to have a few problems, e.g. the lapse function used to lower the energy requirements distorted time within the "warp bubble."
Since the energy problem was dealt in more creative ways such as varying the warp bubbles parameters as suggested by Chris Van Den Broeck (gr-qc/9905084), the ESAA group decided to attack another problem. One of the problems raised with the Alcubierre Warp Drive was that its superluminal nature would be impossible to control. If this were the case then using Warp Drives for superluminal travel would be out of the question, new members joined the ESAA group and decided to construct another paper.
The group wanted to know how superluminal motion would affect null geodesics and how this might be used as a clue to have control with a superluminal warp drive. The second paper put fourth by ESAA was entitled "A Causally Connected Superluminal Warp Drive Space-time (gr-qc/0202021), which proposed varying null geodesics to counter the superluminal problem. With this work several esteemed physicists gave there opinion on the paper, they largely argued against it because horizons will always form with superluminal motion. However ESAA argued against this reasoning as the horizons are still present they are simply moved by a dual light cone interpretation for space-time, the horizons just occur at another place. Expert opinion on this matter was that even if that held up, we couldn't show that a dual light cone interpretation is possible.
From this point ESAA has had some heated arguments, which gained some enemies and made a few friends. It was however mutually agreed that such a paper would never be accepted in an existing journal and so no additional publication was pursed on this paper.
The next paper proposed by the ESAA group was a paper to explore how Warp Drive space-time affect the geodesics of photons. From Alcubierre's original paper it is not to difficult to realize how the geodesics of photons become affected as was shown by Clarke, et. al (gr-qc/9907019). However a Portuguese researcher named Jose Natario showed that energy of the photons distorted by a warp drive would be lethal if traveling near the speed of light (gr-qc/0110086). This proved to be troubling as the popular press picked up on it as being the "Warp Drives are impossible," so ESAA decided to show how Warp Drives could still be possible with these "lethal" photons. It was found that a properly chosen dynamic space-time in several layers could act to slow the dynamic nature of the photons.
This solution ESAA proposed was entitled "On the Problems of Hazardous Matter and Radiation at Faster than Light Speeds in the Warp Drive Space-time" (gr-qc/0207109). However some of the excited authors mistook the slowing dynamics for velocity, when in reality it is the energy that is reduced, so the photons are non lethal.
Further inspection by ESAA and others have shown the lethal photons are fictitious as they exist with a Cauchy Surface, the photons energy doesn't change in the "warp bubble." There's just a frequency shift caused by the Cauchy region, since there is little interest in Warp Drives do the "toy" Alcubierre model ESAA has been slow in correcting this error. For these reasons this paper has not been considered for further publication, but again have shown that warp drives are mathematically feasible. However the ESAA solution dubbed a "shield" from its science fiction counter part does indicate the possibility of a dual light cone region as suggested by the second work which might warrant further investigation.[/i]
Fernando's general idea was to use certain effects to escape off the brane. But while his proposed testing of such with high energy particles could open the door to testing out aspect of the RS model in general, he basically discovered that it does not allow matter to escape the brane. I'm not sure who exactly pointed this out to him since he tended to exit our group again. During his time in our group I had discovered what he was looking at was a brane lensing effect. In studying such I discovered it modifies gravity and the path of particles on and off the brane.Doctor Paul Karl Hoiland - Jan 27, 2004 4:26 pm
In the case of the extra dimension the length or volume is determined by the bulk cosmological constant(1) on both a local and global level. Gravity becomes higher dimensional at scales where
1/r �¨ 1/r^1+N.
But little has ever been mentioned of its modification of the on the brane Minkowski metric as well as the AdS one. Generally, what Fernando had noticed is that if you adjust the local Israel condition you can change the "warp factor" and that regular positive matter can adjust this. Its almost a pity he withdrew that third paper from GRG. With a bit of modification he had a perfect way to alter gravity in any local region which would have been a great test bed for certain Brane Models in general even if it did not support his hyperdrive idea.
I think after looking at this idea one could achieve what to a remote observer was faster travel times even though you never exceed C in the local frame. It literally was the original ST style warp drive. You could travel through a Universe that is smaller with no violations of the laws of physics in either the local or remote region.
Very interesting, Spectrum. It will take me some time to read through, and I almost feel like I'm mucking up the thread with no-so interesting commentary. You've really outdone all of us in this and similar threads.
If I can say anything, it's something I remember reading something of Stanton Friedman's who says that propulsion and energy systems researched and investigated by independent companies where he has worked is often not what is discussed and taught by academia. He talks in terms of space travel and what may be possible for advanced civilizations who have had time to evolve and develop technical capabilities which only seem impossible for man but really would not violate laws of physics that we may not be aware of today. Hawking, fopr example, searched for the last ten years of his life for a law of physics which declares time travel impossible. He still hasn't discovered it and merely says now that time travel would no be practical. On the other hand, Einstein said nothing apparently about travel at speed of light or near light being an impossibility. The physics of it though suggests increasingly large amounts of energy required as velocity approaches light speed. Energy required. And this is at the centre of Kardashev's theory of advanced civilizations based on energy consumption driven by average rate of growth of a modest one per-cent per year. Where would the immense energy be drawn from? Friedman(and Kardashev I suppose) says the answer showers down on us every day, nuclear fusion. A civilization advanced enough would be able to harness the energy of the sun to a much greater degree than we are able to in this day and age. At some point, though, their energy needs would exceed the power of their own sun, at which some point just two and one-half millenia later and advancing technologically at the same modest rate, they could be harnessing the energy of a galaxy. I'll read about Lagrangian points of orbit now though. Fascinating.
Hi Fidel,
As a layman, my interest has been mainly focused on gravity and a means to defy it. How one can see in different ways. I do like to be taken seriously and not as some crank.
The Lagrange Points
Seeing space in a different light helps one to adjust perspective abut the universe and the possibilities of travel. There is indeed a abstractness to such ideas that when one sees the universe in a geometrical way, it helped to push my perspective about tunnels in space. How sound may be used to image WMAP. The three body problem application toward identification of those L positions.
What position is the Space Station occupying?
The bad news is that the bulk of scientific knowledge that we have accumulated to date concludes that faster than light travel is impossible. This is an artifact of Einstein’s Special Theory of Relativity. Yes, there are some other perspectives; tachyons, wormholes, inflationary universe, spacetime warping, quantum paradoxes...ideas that are in credible scientific literature, but it is still too soon to know if such ideas are viable.
One of the issues that is evoked by any faster-than-light transport is time paradoxes: causality violations and implications of time travel. As if the faster than light issue wasn’t tough enough, it is possible to construct elaborate scenarios where faster-than-light travel results in time travel. Time travel is considered far more impossible than light travel.
I believe Einstein was a realist when it came to quantum mechanics, as was Planck et al - they rejected the indeterministic world view of Heisenberg, Bohr, Born etc. And even some of them were realists, like Schrodinger, who developed wave mechanics. But then in 1957, physicist John Stewart Bell demonstrated that some forces must travel faster than speed of light in order to account for observable quantum states. And since this is at odds with Einstein's Theory of Relativity, many physicists today reject the realist position.
This is of course raised my interest when I had heard of "Spooky Action at a Distance." This was the start of "entanglement history" as it is was historically lead from, too today.
Quantum physics questions the classical physical conception of the world and also the everyday life understanding, which is based on our experiences, in principle. In addition, the experimental results lead to new future technologies, which a revolutionizing of communication and computer technologies, how we know them, promise.Further Links for Consideration

Quantity of experiment and the Foundations OF Physics
Professor Anton Zeilinger
In order to exhaust this technical innovation potential, the project "Quantenteleportation was brought over long distances" in a co-operation between WKA and the working group by Professor Anton Zeilinger into being. In this experiment photons in the duct system "are teleportiert" of Vienna, i.e. transferred, the characteristics of a photon to another, removed far. First results are to be expected in the late summer 2002.
Quantum Entanglement Benefits Exist after Links Are BrokenBy Charles Q. Choi
In experiments with quantum entanglement, which is an essential basis for quantum computing and cryptography, physicists rely on pairs of photons. Measuring one of an entangled pair immediately affects its counterpart, no matter how far apart they are theoretically. The current record distance is 144 kilometers, from La Palma to Tenerife in the Canary Islands.
In practice, entanglement is an extremely delicate condition. Background disturbances readily destroy the state—a bane for quantum computing in particular, because calculations are done only as long as the entanglement lasts. But for the first time, quantum physicist Seth Lloyd of the Massachusetts Institute of Technology suggests that memories of entanglement can survive its destruction. He compares the effect to Emily Brontë’s novel Wuthering Heights: “the spectral Catherine communicates with her quantum Heathcliff as a flash of light from beyond the grave.”
The insight came when Lloyd investigated what happened if entangled photons were used for illumination. One might suppose they could help take better pictures. For instance, flash photography shines light out and creates images from photons that are reflected back from the object to be imaged, but stray photons from other objects could get mistaken for the returning signals, fuzzing up snapshots. If the flash emitted entangled photons instead, it would presumably be easier to filter out noise signals by matching up returning photons to linked counterparts kept as references.
Still, given how fragile entanglement is, Lloyd did not expect quantum illumination to ever work. But “I was desperate,” he recalls, keen on winning funding from a Defense Advanced Research Projects Agency’s sensor program for imaging in noisy environments. Surprisingly, when Lloyd calculated how well quantum illumination might perform, it apparently not only worked, but “to gain the full enhancement of quantum illumination, all entanglement must be destroyed,” he explains.
Lloyd admits this finding is baffling—and not just to him. Prem Kumar, a quantum physicist at Northwestern University, was skeptical of any benefits from quantum illumination until he saw Lloyd’s math. “Everyone’s trying to get their heads around this. It’s posing more questions than answers,” Kumar states. “If entanglement does not survive, but you can seem to accrue benefits from it, it may now be up to theorists to see if entanglement is playing a role in these advantages or if there is some other factor involved.”
As a possible explanation, Lloyd suggests that although entanglement between the photons might technically be completely lost, some hint of it may remain intact after a measurement. “You can think of photons as a mixture of states. While most of these states are no longer entangled, one or a few remain entangled, and it is this little bit in the mixture that is responsible for this effect,” he remarks.
If quantum illumination works, Lloyd suggests it could boost the sensitivity of radar and x-ray systems as well as optical telecommunications and microscopy by a millionfold or more. It could also lead to stealthier military scanners because they could work even when using weaker signals, making them easier to conceal from adversaries. Lloyd and his colleagues detailed a proposal for practical implementation of quantum illumination in a paper submitted in 2008 to Physical Review Letters building off theoretical work presented in the September 12 Science. See: more here
There are currently a few experiments that simulate faster than light capabilities given "a medium through which this effect travels." ICECUBE and Pierre Auger experiments all simulate cosmic particle collisions, as does Muon detection experimentation in the LHC Gran Sasso experiment.
Tscan
It was designed to be simple ("trivial") internally, and to have a simple user interface. A lot of importance was given to giving the user a large choice of options to display events in many different ways.
Tscan proved to be a very useful tool for the development of fitters. A particularly useful feature is the ability to show custom data for every photpmultiplier tube (PMT). Instead of the usual time and charge, it can show expected charge, scattered light, likelihood, chi-squared difference, patches, and any other data that can be prepared in a text format.

Within the IceCube collaboration the Univ. of Uppsala and the Univ. of Berkeley have joined the DESY initiative. The DESY team is also in close contact to the groups in Europe, the USA and Asia which are working on acoustic detectors for Neutrino-Telescopes installed in water. Details on the different projects have been presented on the First Workshop on Acoustic Cosmic Ray and Neutrino Detection held at Stanford in September 2003.
The muon will travel faster than light in the ice (but of course still slower than the speed of light in vacuum), thereby producing a shock wave of light, called Cerenkov radiation. This light is detected by the photomultipliers, and the trace of the neutrinos can be reconstructed with an accuracy of a couple of degrees. Thus the direction of the incoming neutrino and hence the location of the neutrino source can be pinpointed. A simulation of a muon travelling through AMANDA is shown here (1.5 MB).
In an interview with Boyd Bushman, he refers to Paul Dirac's theory of a neutrino universe in which matter is non-polarized. In theory, he says, if it was possible to be at one with a neutrino universe, we could travel anywhere in zero time, or iow's, speed of thought.
Michio Kaku on Planck energy propulsion(physics of the impossible at this point in time):
Such technical capabilities may just be a matter of evolution and time, a relatively small amount of time within the larger scheme.
Spooky action at a distance, if I'm not wrong, has actually been observed, so it's not theoretical. So Ursula K. Leguin's "Ansible" from "Left Hand of Darkness" is less fantasticle.
Theoretical physics has been driving things since Einstein, and if anything I've learned as engineering physicists catch up and find ways to test some pretty wacked out ideas like spooky action at a distance it's not to dismiss their ideas no matter how conter intuitive they might be.
Particularly to a guy who likes to live in a Newtonian universe.
That all being said, imagining faster than light travel, or other fantastic ways which would bring a Stark Trek type universe we may want in line with a possible reality doesn't really further debate for me in any satisfying way.
I don't think, based on what we know, that Hawking has anything to worry about. Anything that we earthlings might have can certainly be found closer to our alien overlords. We wouldn't even be of any value as physical slaves.
Love slaves perhaps. I still hold out hope for a race of Betty Page aliens on the planet Latexia.
Hey. With all those planets out there, there's surely to be at least one such planet.
Our knowledge is so limited, and so confined to our experience that we don't even know if we are looking in the right places with the Ceti program.
We keep looking at "earth like stars", based on, well, that we live on earth. And we keep listening on radio. A format that most of us here regard as something of an anachronism.
My thinking is that the only thing another alien species might want from us or give to us is information, because that's about all that can be sent at the speed of light or faster economically, meaning in terms of energy expenditure.
So, maybe we should be looking for some signal from some galactic "library of Alexandria" that's orbiting a stable and long lived brown dwarf or similar star.
The fact that I'm as likely to be correct as any scientist should give us all pause for thought, and illuminate just where we stand on these questions at the moment.
"Former federal defence minister Paul Hellyer, 86, believes not only that aliens have visited Earth but also that they have contributed greatly to human advances.."
Canny aliens, they manage to give us these advances right when other discoveries put us on the very cusp of discovering them ourselves, so as to not tip us off to their existance.
What's even spookier is this. Some of Steven Greer's disclosure project witnesses have stated that they have seen and were made aware of technologies that must be centuries more advanced than what exists in military and public domains today. Yes, there are former US Military officials and other government workers saying that, yes, there is a massive cover up, and that the cover up is ongoing.
These people are, in effect, whistle blowers. And there has been a trend for whistle blowing in the US in recent years. Their's have been the most secretive governments in world history.
And this is so X Files. There is an unconfirmed quote circulated on the internet and attributed to Ben Rich, who allegedly said to a graduating class at UCal: ≈We already have the means to travel among the stars. We can take ET home.
Scientists create artificial mini 'black hole'

IN THE FUTURE Prototypes of Bigelow Aerospace’s Sundancer habitat, which has an inflated volume of 180 cubic meters, at a hangar in North Las Vegas.
By KENNETH CHANG
NORTH LAS VEGAS, Nev. — At the Bigelow Aerospace factory here, the full-size space station mockups sitting on the warehouse floor look somewhat like puffy white watermelons. The interiors offer a hint of what spacious living in space might look like.
“Every astronaut we have come in here just says, ‘Wow,’ ” said Robert T. Bigelow, the company founder. “They can’t believe the size of this thing.”
Four years from now, yada-yada blah blah ...
His space stations are not his only interest in space. “I’ve been a researcher and student of U.F.O.’s for many, many years,” Mr. Bigelow said. “Anybody that does research, if people bother to do quality research, come away absolutely convinced. You don’t have to have personal encounters.”
He added: “People have been killed. People have been hurt. It’s more than observational kind of data.”
This billionaire entrepreneur is fairly broad in his thinking, wouldn't you say?
Universe’s Dark Side Debated
What if the universe is not expanding as fast as astronomers believe that it is? What if dark matter and mysterious dark energy do not exist? Scientists say that if true, it would be shocking. The standard model might be wrong.
Alien hunters 'should look for artificial intelligence'
But Seti astronomer Seth Shostak argues that the time between aliens developing radio technology and artificial intelligence (AI) would be short.
Writing in Acta Astronautica, he says that the odds favour detecting such alien AI rather than "biological" life.
Ufologists have said that it's possible some UFO's could be non-biological or even biological AI entities, and perhaps a type of von Neumann probe sent from other worlds. Are they self-replicating? One has to have an imagination to even think it. I think younger babblers may not think it so fantastic with some being the enthusiasts of modern sci-fi that they are. OTOH, there are a number of scientists today who have suggested the same thing.
New French aerospace report endorses reality of UFOs
"Mr. Mulder, they have been here for a long, long time."
Exploring our dark universe is often the domain of extreme physics. Traces of dark matter particles are searched for by huge neutrino telescopes located underwater or under Antarctic ice, by scientists at powerful particle colliders, and deep underground. Clues to mysterious dark energy will be investigated using big telescopes on Earth and experiments that will be launched into space.
But an experiment doesn’t have to be exotic to explore the unexplained. At the International Conference on High Energy Physics, which ended today in Paris, scientists unveiled the first results from the GammeV-CHASE experiment, which used 30 hours’ worth of data from a 10-meter-long experiment to place the world’s best limits on the existence of dark energy particles. CHASE, which stands for Chameleon Afterglow Search, was constructed at Fermilab to search for hypothetical particles called chameleons. Physicists theorize that these particles may be responsible for the dark energy that is causing the accelerating expansion of our universe.
“One of the reasons I felt strongly about doing this experiment is that it was a good example of a laboratory experiment to test dark energy models,” says CHASE scientist Jason Steffen, who presented the results at ICHEP. “Astronomical surveys are important as well, but they’re not going to tell us everything.” CHASE was a successor to Fermilab’s GammeV experiment, which searched for chameleon particles and another hypothetical particle called the axion.

NASA finds dozens of planets that might support life The Kepler mission has discovered 1,235 possible planets, including 54 in the 'Goldilocks range' — just far enough from their stars to be neither too hot nor too cold for liquid water.

UN must prepare for close encounters with aliens, says scientist
Might there be ET's who were smart enough long ago not to have designed an economy based on dead plants as an energy source? What if they are tens of thousands of years more technically advanced than us? A million years more advanced? Hundreds of millions of years more evolved than us? Will they have known about our existence for a long time?
I don't have much of an opinion on aliens or the rest of the cosmos, but....if there are any Aliens coming here to Earth, I would assume they are far more advanced then us. Why or why not make direct contact with us is totally coming from them knowing this, I would surmise.

Yep, I wonder if for aliens that coming to earth wouldn't be like a visit to the zoo. I've been to the zoo, and I've wondered if I would be able to help the chimpanzees break out of prison or something. lol Give them an oxy-acetylene blow torch, a map and GPS, some black pygamas, repelling equipment and a pep talk. Would they understand me or eventually figure out how to use the high technology intended to boost their odds a little? Or would the odds be better that chimps evolved into a technically advanced species on some other planet?
The USA only needs Will Smith to fly into the Mothership and save the planet. All this money spent on the moon is waste. Or you know, these aliens will die because of the bacteria on earth that they are not immune to.
And besides, that aliens would come all the way here to exploit our resouces and us, for their form of Capitalism. Cause Capitalism is the best.
So what's out is Space? They're working on it I guess? But I do love looking at all those picture they take, quite amazing really.
I love when humans do extrodinary things like lounch rockets and put men on the moon.
I wonder where they got the wild idea that motherships are like a mile or two in length? Astronauts and cosmonauts would surely see something that size. Crazy.
That could be one reason why aliens aren't socializing with the general population, they're avoiding bacterial infections. I think there was a book written about it, Guns, Germans and Steel or something.
So that's why Darwin packed his bags and went on long voyages to remote islands. He needed money and so joined an exotic bird smuggling ring? I knew it. That capitalist dog!
I always like to imagine that some day we will discover we are just in the middle of a big petri dish.
NASA FINDS EARTH-SIZE PLANET CANDIDATES IN HABITABLE ZONE, SIX PLANET SYSTEM
MOFFETT FIELD, Calif. -- NASA's Kepler mission has discovered its first Earth-size planet candidates and its first candidates in the habitable zone, a region where liquid water could exist on a planet's surface. Five of the potential planets are near Earth-size and orbit in the habitable zone of smaller, cooler stars than our sun.
Candidates require follow-up observations to verify they are actual planets. Kepler also found six confirmed planets orbiting a sun-like star, Kepler-11. This is the largest group of transiting planets orbiting a single star yet discovered outside our solar system.
"In one generation we have gone from extraterrestrial planets being a mainstay of science fiction, to the present, where Kepler has helped turn science fiction into today's reality," said NASA Administrator Charles Bolden. "These discoveries underscore the importance of NASA's science missions, which consistently increase understanding of our place in the cosmos."
Bill Borucki, Kepler PI
The discoveries are part of several hundred new planet candidates identified in new Kepler mission science data, released on Tuesday, Feb. 1. The findings increase the number of planet candidates identified by Kepler to-date to 1,235. Of these, 68 are approximately Earth-size; 288 are super-Earth-size; 662 are Neptune-size; 165 are the size of Jupiter and 19 are larger than Jupiter. Of the 54 new planet candidates found in the habitable zone, five are near Earth-sized. The remaining 49 habitable zone candidates range from super-Earth size -- up to twice the size of Earth -- to larger than Jupiter.
The findings are based on the results of observations conducted May 12 to Sept. 17, 2009, of more than 156,000 stars in Kepler's field of view, which covers approximately 1/400 of the sky.
"The fact that we've found so many planet candidates in such a tiny fraction of the sky suggests there are countless planets orbiting sun-like stars in our galaxy," said William Borucki of NASA's Ames Research Center in Moffett Field, Calif., the mission's science principal investigator. "We went from zero to 68 Earth-sized planet candidates and zero to 54 candidates in the habitable zone, some of which could have moons with liquid water."
Among the stars with planetary candidates, 170 show evidence of multiple planetary candidates. Kepler-11, located approximately 2,000 light years from Earth, is the most tightly packed planetary system yet discovered. All six of its confirmed planets have orbits smaller than Venus, and five of the six have orbits smaller than Mercury's. The only other star with more than one confirmed transiting planet is Kepler-9, which has three. The Kepler-11 findings will be published in the Feb. 3 issue of the journal Nature.
Jack Lissauer, Kepler Co-Investigator
"Kepler-11 is a remarkable system whose architecture and dynamics provide clues about its formation," said Jack Lissauer, a planetary scientist and Kepler science team member at Ames. "These six planets are mixtures of rock and gases, possibly including water. The rocky material accounts for most of the planets' mass, while the gas takes up most of their volume. By measuring the sizes and masses of the five inner planets, we determined they are among the lowest mass confirmed planets beyond our solar system."
All of the planets orbiting Kepler-11 are larger than Earth, with the largest ones being comparable in size to Uranus and Neptune. The innermost planet, Kepler-11b, is ten times closer to its star than Earth is to the sun. Moving outward, the other planets are Kepler-11c, Kepler-11d, Kepler-11e, Kepler-11f, and the outermost planet, Kepler-11g, which is half as far from its star as Earth is from the sun.
The planets Kepler-11d, Kepler-11e and Kepler-11f have a significant amount of light gas, which indicates that they formed within a few million years of the system's formation.
"The historic milestones Kepler makes with each new discovery will determine the course of every exoplanet mission to follow," said Douglas Hudgins, Kepler program scientist at NASA Headquarters in Washington.
Kepler, a space telescope, looks for planet signatures by measuring tiny decreases in the brightness of stars caused by planets crossing in front of them. This is known as a transit.
Since transits of planets in the habitable zone of sun-like stars occur about once a year and require three transits for verification, it is expected to take three years to locate and verify Earth-size planets orbiting sun-like stars.
Debra Fischer
The Kepler science team uses ground-based telescopes and the Spitzer Space Telescope to review observations on planetary candidates and other objects of interest the spacecraft finds. The star field that Kepler observes in the constellations Cygnus and Lyra can only be seen from ground-based observatories in spring through early fall. The data from these other observations help determine which candidates can be validated as planets.
Fidel,
"The United States military are preparing weapons which could be used against the aliens, and they could get us into an intergalactic war without us ever having any warning...The Bush Administration has finally agreed to let the military build a forward base on the moon, which will put them in a better position to keep track of the goings and comings of the visitors from space, and to shoot at them, if they so decide."
They would be in contravention of the Treaty of 1967 which states,
From what i've read I was beginning to think the end of man would be caused by plagues or by nano-weaponry, chemical or biological WMD. And that's an increasingly realistic danger. I've read where nuclear weapons are considered passe by modern militarists and would-be megalomaniacs. Not nuclear? Not again, I thought. Way too messy and damages too much real estate in trying to imagine myself one of the most insane people ever to be in charge of things.
And I wish it was true. I, too, thought that since the end of cold war international leaders have finally come to their senses and began to realize that nuclear weapons should be decommissioned, dismantled, and scrapped for all time. And lots of people believe that this must surely be the case today after such a costly cold war that almost resulted in the end of habitable earth. But it's not true. Star Wars plans to weaponize space during the Reagan era was a reality, and it looks as if space is the final frontier for world domination. The irony of it is that the country with the most to lose in space are the cold war victors. Their economic and forward operating military dependence on satellite communications makes the US the most vulnerable to disruptions by relatively cheap methods of anti-satellite weaponry. I believe we've reached the edge and staring over the abyss. This is the last window of opportunity to end the madness. Mankind is now standing before the dreaded precipice.

Will we ever look up at the skies again in the same way? Are there intelligent beings out there looking back at us right now? I think this is the beginning of what will be the most important event in history for mankind. And I really don't think we have to worry about them coming to raid what's left of our oil and gas reserves. I think it is ridiculous to assume an intelligent species is still dependent on oil or was ever. Hawking was surely pulling our legs with his warning. If they do come here or contact us, then I think it will be for a much more important purpose than imperialism.

Explanation: Here's a familiar shape in an unfamiliar location! This emission nebula is famous partly because it resembles Earth's continent of North America. To the right of the North America Nebula, cataloged as NGC 7000, is a less luminous Pelican Nebula. The two emission nebula measure about 50 light-years across, are located about 1500 light-years away, and are separated by a dark absorption cloud. The nebulae can be seen with binoculars from a dark location. Look for a small nebular patch north-east of bright star Deneb in the constellation of Cygnus. It is still unknown which star or stars ionize the red-glowing hydrogen gas.

Okay so we line up all duplicates of you, babbler you, yourself, thee and so on , and ask them, Will the real you please step forward? Which of them will answer, 'Yo! Here I am, you fools!' ?
I understand a bit of what Greene and others suggest when they talk about duplicates of our universe. But I don't understand what they are implying when they go so far as to suggest duplicates of our individual selves. I do totally agree that our underrstanding of the size, or boundary, of the universe has always been expanding. And I can understand how the expansion of our knowledge is taking us to theories on multiverses. But, like you, I also have trouble resolving how repreatable, mirror-like, or multiversal human nature can be. Brings new meaning to the phrase "we think as one".
This is an interesting article on dark energy and how it relates to multiverse theories. I think understanding dark-matter, dark-energy or dark-forces could go a long way to resolving Einstein's conundrum.
I have no idea, but it's fascinating just the same. A man and wife astronomer team in the US recently compared dark flow of the universe to a partial carton of milk. The contents of the carton seem to be sliding in one direction at a million miles per hour, they said. It's suggested that there is something very large out there beyond the edge of the universe and pulling all of the galaxies in its direction. I think the article you pointed us to, Sknguy, suggests something similar. Could it be another universe? Or is there a simpler explanation? In any event, it looks like they are stuck with dark energy for a while. Mysterious dark energy apparently makes up some large percentage of the matter in the universe, and they know very little about it. Does DE represent Einstein's cosmological constant? Some physicists think so.
There's a lot more in the palms of our hands than we realize. And the "edge of the universe" could be just a metaphor for something that's likely not far from our reaches. Dark-whatever is likely the link to the multiverse. Einstein couldn't link the relationship between space-time and matter, or general and special relativity, into a theory of everything. What flavour of string theory holds true will likely resolve that. And I think DE is very much a part of the relationship. On an aside, at anoither forum I posted a newbee question about wanting to understand the relationship between matter and space-time. And the best response I got was "Most people spend their lives trying to understand that relationsiip."
That's a good question. I don't know either other than to repeat what I've read. Space-time, according to Einstein and so on, is like a flowing river. It can have branches and fork into new paths. And space-time can result in whirlpools apparently. I think the whirlpools may be black holes or perhaps wormholes. Einstein said, through his equations, that it may be possible to travel in time through hyperspace by way of wormholes. No one knows if this would ever be possible. It may be possible in the distant future given a certain amount of human evolution and plenty of technological advancement. We haven't been a technically advanced species for very long at all.
UFO sightings have been made public by the FBI BBC interview with Nick Pope. Nothing astounding about the FBI releases. Something for skeptics and believers alike, and a lot of the reports were nonsense as well.
Space is the boundless, three-dimensional extent in which objects and events occur and have relative position and direction.[1] Physical space is often conceived in three linear dimensions, although modern physicists usually consider it, with time, to be part of the boundless four-dimensional continuum known as spacetime. In mathematics one examines 'spaces' with different numbers of dimensions and with different underlying structures. The concept of space is considered to be of fundamental importance to an understanding of the physical universe although disagreement continues between philosophers over whether it is itself an entity, a relationship between entities, or part of a conceptual framework.
The definitions of Space are a necessary part of workng toward what others may be saying. Is Greene talking about symmetry?
I think he's talking about curved space(Einstein), curvilinear space, "D branes", "flops", phase diagrams etc. He's talking about compact dimensions far too small to see with the human eye and perhaps dimensions which may be far too large to observe with the human eye. I dunno about all those fancy ideas. But I think he is definitely not describing things in terms of flat world Euclidean geometry.
I think some of these modern day theoretical physicists believe that study of the very small, the sub-atomic and quantum, is a model of the universe all around us. And I don't really understand what they are talking about. Not a lot.
I'm not sure. My understanding of symmetry is what existed at the moment before big bang. Everything there is in the universe today was once compressed into an infinitely small and hot tiny bit of something or other called the singularity. 14 billion years ago, nothing existed outside of it, not gravity, time nor light or anything else that they know of. And ever since then everything is increasingly non-symetrical since expansion of the universe began. And now they realize there is a mysterious force causing everything to expand at a greater rate than they can account for given the previously estimated amount of matter in the universe. There is something else out there, and they think it's dark energy and representing Einstein's cosmological constant. I think Einstein made it up for the sake of making his equations balance, but now it's thought to be real.

By recording the traces cosmic rays make as they pass through, the AMS might uncover a universe that is now invisible. Although Ting is hesitant to make predictions about what the instrument will find, he said the instrument was designed with dark matter and antimatter in mind. Very little is known about dark matter although it makes up an estimated 90 percent of the mass in the universe.Although Earth-based facilities have been built to create powerful streams of subatomic particles, Ting said their limits are more than 14 million times weaker than the power produced by cosmic rays in space.
"No matter how large an accelerator you build, you're not going to compete with space," Ting told reporters recently. Ting offered the news media a close look at the AMS before it was packed for loading into Endeavour's cargo bay for launch.

If you follow many earth based experiments going on with regard to the idea of cosmic particle collisions this is a project well in hand and in relation to the man-made experiments going on at the LHC, ICECUBE and SNO etc.
(Filed: 07/09/2001) By colliding gold nuclei at huge energies, the RHIC is investigating "quark-gluon plasma", a state of matter in which the fundamental sub-nuclear particles, called quarks and gluons, become unstuck and swill around in a kind of particle soup that should have been around shortly after the Big Bang.
Dr Allanach warned that if experiments with the RHIC go wrong, it could produce a new hypothetical kind of particle called the killer strangelet.
In a catastrophic chain reaction, the killer strangelet would gobble up nuclei until it had eaten a million billion, when its weight would pull it towards the centre of the earth.
Something disturbing though is what is speculated about strangelets with which I thought had been long resolved according to LHC investigations? It seems to have reappeared, is quite shocking really for me considering the responses to the disaster scenarios speculated by court challenges not so long ago.
The creepy part of these kind of discussions is that one doesn't say that RHIC collisions "create" black holes, but that nucleus-nucleus collisions, and even proton-proton collisions, are in some sense black holes, albeit black holes in some sort of "dual" space which makes the theory easier.
The statements made by proponents of the LHC to quell the fear mongering that went on as long as those disaster scenarios played out n in experimental backdrops revealed in the collision process.
The study of high energy physics, also known as particle physics, grew out of nuclear and cosmic ray physics in the 1950’s, and measured the properties and interactions of fundamental particles at the highest energies (millions of electron-volts) then available with a relatively new technology, particle accelerators. Today that technology has advanced so that forefront particle accelerators produce exquisitely controlled beams with energies of trillions of electron-volts and intense enough to melt metal. The science has advanced with the technology to study ever-higher energies and very rare phenomena that probe the smallest dimensions we can see and tell us about the very early history of our universe. While the science has revolutionized our understanding of how the universe works, elements of the technology have helped transform other fields of science, medicine, and even everyday life. The science and its impacts will be remembered as one of the highlights of the history of the late 20th century.
Gamma-ray bursts. We tend to think of them as big explosions - but it has been suggested that they might actually be Small Bangs. Credit: NASA.
Short duration gamma-ray bursts more often occur in regions of low star formation and are not associated with supernovae. Their duration is technically less than 2 seconds, but a duration of only a few milliseconds is not unusual. These are assumed to result from collisions between massive compact objects – perhaps neutron stars or black holes – producing a short, sharp outburst of energy.

3-day Solar-Geophysical Forecast issued May 27 22:00 UTC Solar Activity Forecast: Solar activity is expected to be low with a chance for C-class events, and a slight chance for an M-class event, as regions on the disk continue to evolve.
Geophysical Activity Forecast: The geomagnetic field is expected to be predominately unsettled with occasional active periods, including isolated minor storm conditions at high-latitudes for day one (28 May). This is expected due to effects from the recurrent coronal hole high speed stream (CH HSS). In addition there are possible effects from the disappearing filament observed on 25 May. Quiet to unsettled conditions, with isolated active levels, are expected for days two and three (29-30 May) with continued CH HSS effects. See: Today's Space Weather

Into the Antiworld was originally staged at CERN inside the underground cavern that houses the Delphi experiment, in which collisions between electrons and their antiparticles - positrons - are studied. That setting must have been awe-inspiring, particularly as the show closed. The audience would have been whisked from the wonder and novelty of Dirac's theory over 70 years ago to the sophisticated particle physics experiments of today that the discovery inspired. At CERN, the curtain behind the stage ripped apart to reveal the Delphi detector the performance ended - but the gigantic photograph of the Delphi experiment that concluded the show at the Bloomsbury worked surprisingly well.

Ah Mike it's really not that difficult to think outside of the way you've always thought? With a "little more information" things change, and perspective can change.
I think market ideology "is a algorithm" that was developed to see if it could fly, and of course, with us as consumers we make it happen?:) Does it ever fail.....we may not yet all recognize the signals.....yet some may, and do.
Strange things can still happen out of the norm in the world that defies our logic and reasoning? Why would one question one's reality based on spirituality, or, if they talk to plants. Speak to animals, or, fly in their dreams. if it works for them...... why are there are some scientists who can work outside of that mainstream and feel okay with that....I wish I had examples. They leave room for the subjectivity of experience with the hopes people can bring something out of it.
I believe it would be a serious mistake not to have some grounding factor, as an inductive/deductive relationship with the world. Something that we all can test and try. Would you throw out the Justice system?
Well the problem with the grounding factor is the aristotalianisation of it that we are currently caged in spec, the idiot in that painting pointing his finger downward and subsequently debasing the imagination and the possibilities of transfiguration. I very much agree with Nietzsche's call to defy gravity within as much practicality as possible, this is not to say that conratized aspects of our existence should be ignored untill they are possibly dissolved. Imagine if these intesified technological adendums based on the technics of the printing press and the steam engine+oil had been made to iching or vedic or mayan based discourses as opposed to the boring groudless grounding of aristotalian assumptions backed by the roman ordering machine that it played surrogate to, perhaps we'd be playing with wormholes by now or doing the post earth colony thing. As Jared Diamond descriptively points out, these things come down to happy or tragic accidents, but we have the hindsight to see these tragedies and simply start flying yesterday already, give those inductive/deductive aristotalian usefull fiktions some wings and the scientists something to be gay about.
To answer you're last Q, I would never have brought it in in the first place, terms like justice are perfect examples of overlocalised inside-outside organizational definitions and assumptions that are devoid of emergent spatial twists and turns.
PLato said,"Look to the perfection of the heavens for truth," while Aristotle said "look around you at what is, if you would know the truth"
Ah yes you can see the relationship between Plato and Aristotle in the painting by Raphael? Because it resides in the signatory's room in the Vatican does not give credence to the Catholic church itself but is a recognition by Raphael of what is current as a grounding factor proposed by Aristotle.
It is a Socratic method of approach, not only in Justice, but of education itself. Would you overhaul both. Do you have some technological means? Sports?
Well on plato I tend to think that for the most part you can look at his analysis as simply a metophorical explanation of the world, I prefer how the taoist do it compared to him but I do think adendums to his thought like North whitehead bring more to the table then you're run of the mill reductionists, at the end of the day you cant avoid things like metaphor as a means of explaining the world so lets awknowledge this and bring back some aesthetics and imagination into the process, I tend to think the mind based view of phenomena has been proven the more correct analysis and seems to be backed up in such things as quantum mechanics and over all has provided better analysis and thinkers respectively.
Would I overhaul justice and education, yes at least in their in-out intentional forms, I think that an emergence theory and practice of human relations can better make up for these things, I posted a video displaying the power of emergent education in another thread, I think you can apply that to anything in human relations, organizational theory should be after the fact concerning emergent things on the ground.

"Well other than the fact that improper replication of the DNA molecule causes disease, we've understood nothing else".
Apparently they did understand something very important. And they hadn't studied English. Amazing.
Our attempt to justify our beliefs logically by giving reasons results in the "regress of reasons." Since any reason can be further challenged, the regress of reasons threatens to be an infinite regress. However, since this is impossible, there must be reasons for which there do not need to be further reasons: reasons which do not need to be proven. By definition, these are "first principles." The "Problem of First Principles" arises when we ask Why such reasons would not need to be proven. Aristotle's answer was that first principles do not need to be proven because they are self-evident, i.e. they are known to be true simply by understanding them.Yes no doubt. But as you look through the experiment present by Youtube something very important is realized that as a "data base" and Google's connection to it, allow an excursion for children that we would want applied to "all thinking beings" as a vast resource made available to them, having considered the Grandmothers as part of the cloud of encouragement toward progressing and developing. Teachers can come in many forms?
So yes I see education in this way as well...but imagine if such a data base is taken away......imagine being devoid of the technology?
You want to see the children apply such a tool .....being devoid of the technology as to a method inherent in their own design and makeup which will grant them the same benefits as you would have, having gone through such an experiment?
What did they learn that was algorithmic pleasing that Arthur C Clarke might embrace as to all teachers? Replace teachers with Grandmother Cloud?
These things are being considered now in the future development of education as I have research it.....but there is something deeper that must be transmitted that can only be done with the interaction of the teachers....while still accessing that data, you still need the teachers there.
Imagine a "gogle search feature" as the very last "self evident question." This is internal and not attached to the keyboard computerized developer algorithmic code, but is a feature of the human being searching, looking for answers, and becoming their own teachers as well as students. This the independence you want transmitted to children from teachers, as well as too, adults in my view. The teacher, and student are one.
You of course recognize the grounding factor...all I am saying is this inductive /deductive process is part of the need for individuals to excel, regardless of that technology.

Space: What's out there!
One has to assume a foundational perspective from which one can look at the universe?
Did Plato' summation reveal attributes of the Near Death Experience? I wonder?
It seems logical to me if you study from that standpoint, then this too would appear as if it is a subject "outside of time." The assumption is that in order to remember we have to remove "the coat... we put on in order to strip away how forgetfulness is changed by our immersion into the matter states? If everythng already exists in the universe that ever was, and ever will be, then this too would include, birth and death?
Everything then, exists in this space? You try to tap into that?
"Well other than the fact that improper replication of the DNA molecule causes disease, we've understood nothing else".

I think what was meant, is the kids found out how to use google translator?
Yes, probably. They were twelve at the time.
I think the one on the left taught herself to be the teacher. Such noble faces.
