God abhors a naked singularity.
Stephen Hawking

If any one of about 40 physical qualities had more than slightly different values, life as we know it could not exist.
Stephen Hawking
Image
I'm not afraid of death, but I'm in no hurry to die. I have so much I want to do first.
Stephen Hawking

One can't predict the weather more than a few days in advance.
Stephen Hawking
Image
When I get to heaven I'm gonna find the guy in charge of the weather and kick his rear.
Stephen Hawking

There are too many accidents that can befall life on a single planet.
Stephen Hawking
Image
One can't prove that God doesn't exist. But science makes God unnecessary. The laws of physics can explain the universe without the need for a creator.
Stephen Hawking
Image
I believe things cannot make themselves impossible.
Stephen Hawking

I think the brain is essentially a computer and consciousness is like a computer program. It will cease to run when the computer is turned off. Theoretically, it could be re-created on a neural network, but that would be very difficult, as it would require all one's memories.

People who boast about their I.Q. are losers.
Stephen Hawking

One, remember to look up at the stars and not down at your feet. Two, never give up work. Work gives you meaning and purpose and life is empty without it. Three, if you are lucky enough to find love, remember it is there and don't throw it away.

Not to leave planet Earth would be like castaways on a desert island not trying to escape...Sending humans to other planets ... will shape the future of the human race in ways we don't yet understand, and may determine whether we have any future at all.

To my mathematical brain, the numbers alone make thinking about aliens perfectly rational.
Stephen Hawking
Image
As a child, I wanted to know how things worked and to control them. With a friend, I built a number of complicated models that I could control. It was a natural next step to want to know how the universe works.
Stephen Hawking

We each exist for but a short time, and in that time explore but a small part of the whole universe
Stephen Hawking
Image
A picture is worth a thousand words...and uses up a thousand times the memory.
Stephen Hawking

It is generally recognised that women are better than men at languages, personal relations and multi-tasking, but less good at map-reading and spatial awareness. It is therefore not unreasonable to suppose that women might be less good at mathematics and physics.
Stephen Hawking

In effect, we have redefined the task of science to be the discovery of laws that will enable us to predict events up to the limits set by the uncertainty principle.

The beatings will continue until morale improves.

If you lined up all the cars in the world end to end, someone would try to pass them.
