Originál: (en) 'To ask what happened before the universe began is like asking for a point on the Earth at 91 degrees north latitude; it just is not defined. Instead of talking about the universe begin created, and maybe coming to an end, one should say:"The universe is."

Stephen Hawking: Citáty anglicky
“Disorder increases with time because we measure time in the direction in which disorder increases.”
Zdroj: A Brief History of Time (1988), Ch. 9
Kontext: Just like a computer, we must remember things in the order in which entropy increases. This makes the second law of thermodynamics almost trivial. Disorder increases with time because we measure time in the direction in which disorder increases. You can’t have a safer bet than that!
“God abhors a naked singularity.”

Kontext: Many people would claim that the boundary conditions are not part of physics but belong to metaphysics or religion. They would claim that nature had complete freedom to start the universe off any way it wanted. That may be so, but it could also have made it evolve in a completely arbitrary and random manner. Yet all the evidence is that it evolves in a regular way according to certain laws. It would therefore seem reasonable to suppose that there are also laws governing the boundary conditions.
“Women. They are a complete mystery.”

“The greatest enemy of knowledge is not ignorance. It is the illusion of knowledge.”

In his comment that he "used to think that information was destroyed in black holes", he is referring to the black hole information paradox.
Heard in person by this contributor when Hawking showed-up in a Caltech physics class taught by Robert Christy in 1980 or '81; when asked about collapse of the state-vector he whispered to his assistant Chris (surname unknown) something at which point Chris stood up and said 'Stephen is paraphrasing Herman Göring by saying "When I hear the words 'Schrödinger's Cat' I reach for my gun."'.
