Stephen Hawking

Science is not only a disciple of reason but, also, one of romance and passion.

The whole history of science has been the gradual realization that events do not happen in an arbitrary manner, but that they reflect a certain underlying order, which may or may not be divinely inspired.

I believe the simplest explanation is, there is no God. No one created the universe and no one directs our fate. This leads me to a profound realization that there probably is no heaven and no afterlife either.

Even if there is only one possible unified theory, it is just a set of rules and equations. What is it that breathes fire into the equations and makes a universe for them to describe?

The universe is not indifferent to our existence — it depends on it.

I think computer viruses should count as life. I think it says something about human nature that the only form of life we have created so far is purely destructive. We've created life in our own image.

Work gives you meaning and purpose and life is empty without it.

I have so much that I want to do. I hate wasting time.

The downside of my celebrity is that I cannot go anywhere in the world without being recognized. It is not enough for me to wear dark sunglasses and a wig. The wheelchair gives me away.

I believe that the long-term future of the human race must be in space.

The human race is just a chemical scum on a moderate-sized planet, orbiting around a very average star in the outer suburb of one among a hundred billion galaxies.

So Einstein was wrong when he said, 'God does not play dice.' Consideration of black holes suggests, not only that God does play dice, but that he sometimes confuses us by throwing them where they can't be seen.

Black holes ain't as black as they are painted.

It would not be much of a universe if it wasn't home to the people you love.

The radiation from black holes is not dependent on the details of the collapse, only on the mass, angular momentum, and charge. This suggests that black holes have entropy, and that they are hot.

Science predicts that many different kinds of universe will be spontaneously created out of nothing. It is a matter of chance which we are in.

The human capacity for guilt is such that people can always find ways to blame themselves.

I don't think the human race will survive the next thousand years, unless we spread into space.

When one's expectations are reduced to zero, one really appreciates everything one does have.

The boundary condition of the universe is that it has no boundary.
