Stephen HawkingThinkers

The Big bang is difficult to explain outside of the temporal presuppositions we bring to it. To ask what existed before it is like asking what is north of the north pole, a meaningless question.

Common sense is just another name for the prejudices we've been taught all our lives.

Disability is like this: one must take care not to be disabled in spirit as well as physically.

The Equation is just the boring part of mathematics. The fun part is seeing things in terms of geometry.

God is unnecessary because the very fact of a law such as the law of gravity allows (and one might say requires) the universe to create itself from nothing.

Hawking's turtles is on our radar. Try again later or consider contributing!

Intelligence is the ability to adapt to change.

Quantum theory is not only God playing dice; he sometimes even throws the dice where they cannot be seen.

Science is a discipline of romance and passion in addition to being a disciple of reason.

Time is, in general relativity, just a coordinate that labels events in the universe. It does not have any meaning outside the spacetime manifold. To ask what happened before the universe began is like asking for a point on the earth at 91 [degree] north latitude... it is just not defined.

Time is relative because it is an element of space-time.
