Stephen Hawking Quotes

We must develop as quickly as possible technologies that make possible a direct connection between brain and computer, so that artificial brains contribute to human intelligence rather than opposing it.

~ Stephen Hawking

As Irving Good realised in 1965, machines with superhuman intelligence could repeatedly improve their design even further, triggering what Vernor Vinge called a 'singularity.'

~ Stephen Hawking

People won't have time for you if you are always angry or complaining.

~ Stephen Hawking

Even if it turns out that time travel is impossible, it is important that we understand why it is impossible.

~ Stephen Hawking

It's time to commit to finding the answer, to search for life beyond Earth. Mankind has a deep need to explore, to learn, to know. We also happen to be sociable creatures. It is important for us to know if we are alone in the dark.

~ Stephen Hawking

Women. They are a complete mystery.

~ 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

I would like nuclear fusion to become a practical power source. It would provide an inexhaustible supply of energy, without pollution or global warming.

~ Stephen Hawking

I think we have a good chance of surviving long enough to colonize the solar system.

~ Stephen Hawking

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.

~ Stephen Hawking

Not only does God play dice, but... he sometimes throws them where they cannot be seen.

~ Stephen Hawking

A few years ago, the city council of Monza, Italy, barred pet owners from keeping goldfish in curved bowls... saying that it is cruel to keep a fish in a bowl with curved sides because, gazing out, the fish would have a distorted view of reality. But how do we know we have the true, undistorted picture of reality?

~ Stephen Hawking

Time travel was once considered scientific heresy, and I used to avoid talking about it for fear of being labelled a 'crank.'

~ Stephen Hawking

I entered the health care debate in response to a statement in the United States press in summer 2009 which claimed the National Health Service in Great Britain would have killed me off, were I a British citizen. I felt compelled to make a statement to explain the error.

~ Stephen Hawking

I don't have much positive to say about motor neuron disease, but it taught me not to pity myself because others were worse off, and to get on with what I still could do. I'm happier now than before I developed the condition.

~ Stephen Hawking

I don't have much positive to say about motor neurone disease. But it taught me not to pity myself because others were worse off, and to get on with what I could still do.

~ Stephen Hawking

It was Einstein's dream to discover the grand design of the universe, a single theory that explains everything. However, physicists in Einstein's day hadn't made enough progress in understanding the forces of nature for that to be a realistic goal.

~ Stephen Hawking

Success in creating AI would be the biggest event in human history. Unfortunately, it might also be the last, unless we learn how to avoid the risks.

~ Stephen Hawking

Look up at the stars and not down at your feet. Try to make sense of what you see, and wonder about what makes the universe exist. Be curious.

~ Stephen Hawking

However difficult life may seem, there is always something you can do and succeed at.

~ Stephen Hawking

God is the name people give to the reason we are here. But I think that reason is the laws of physics rather than someone with whom one can have a personal relationship. An impersonal God.

~ Stephen Hawking

I have noticed even people who claim everything is predestined, and that we can do nothing to change it, look before they cross the road.

~ Stephen Hawking

The radiation left over from the Big Bang is the same as that in your microwave oven but very much less powerful. It would heat your pizza only to minus 271.3*C - not much good for defrosting the pizza, let alone cooking it.

~ Stephen Hawking

The past, like the future, is indefinite and exists only as a spectrum of possibilities.

~ Stephen Hawking
