Hawking on God
Physicist Stephen Hawking says God wasn't necessary for the creation of the universe.
In his new book, "The Grand Design," the British scientist says unraveling a complex series of theories will explain the universe. The book, written with American physicist and author Leonard Mlodinow, will be published Sept. 9.
In an extract published Thursday in The Times, Hawking wrote that it was "not necessary to invoke God."
