You may see a cup of tea fall off a table and break into pieces on the floor... But you will never… — Stephen Hawking Copy Share Image
I had not expected 'A Brief History of Time' to be a best seller. It was my first popular book and aroused… — Stephen Hawking Copy Share Image
Now, radical forward thinking is offering hope for the future: Replacement body parts to order. A team of scientists in California believe… — Stephen Hawking Copy Share Image
In the past, there was active discrimination against women in science. That has now gone, and although there are residual effects, these… — Stephen Hawking Copy Share Image
Time travel used to be thought of as just science fiction, but Einstein's general theory of relativity allows for the possibility that… — Stephen Hawking Copy Share Image
“You can't afford to be disabled in spirit as well as physically. People won't have time for you.” — Stephen Hawking Copy Share Image
Even if it turns out that time travel is impossible, it is important that we understand why it is impossible. — Stephen Hawking Copy Share Image
The past, like the future, is indefinite and exists only as a spectrum of possibilities. — Stephen Hawking Copy Share Image
Time travel was once considered scientific heresy, and I used to avoid talking about it for fear of being labelled a 'crank.' — Stephen Hawking Copy Share Image
I was not a good student. I did not spend much time at college; I was too busy enjoying myself. — Stephen Hawking Copy Share Image
There are no black holes - in the sense of regimes from which light can't escape to infinity. There are however apparent… — Stephen Hawking Copy Share Image
We each exist for but a short time, and in that time explore but a small part of the whole universe — Stephen Hawking Copy Share Image
In real time, the universe has a beginning and an end at singularities that form a boundary to space-time and at which… — Stephen Hawking Copy Share Image
Most people don't have time to master the very mathematical details of theoretical physics. — Stephen Hawking Copy Share Image
Or in other words, why does disorder increase in the same direction of time as that in which the universe expands? — Stephen Hawking Copy Share Image
I think the human race doesn't have a future if we don't go into space. We need to expand our horizons beyond… — Stephen Hawking Copy Share Image
I put a lot of effort into writing 'A Briefer History' at a time when I was critically ill with pneumonia because… — Stephen Hawking Copy Share Image
“Quantum physics might seem to undermine the idea that nature is governed by laws, but that is not the case. Instead it… — Stephen Hawking Copy Share Image
“Our very existence imposes rules determining from where and at what time it is possible for us to observe the universe. That… — Stephen Hawking Copy Share Image
Just like a computer, we must remember things in the order in which entropy increases. This makes the second law of thermodynamics… — Stephen Hawking Copy Share Image
It is a waste of time to be angry about my disability. One has to get on with life and I haven't… — Stephen Hawking Copy Share Image
Because imaginary time behaves like another direction in space, histories in imaginary time can be closed surfaces, like the surface of the… — Stephen Hawking Copy Share Image
“We have finally found something that doesn’t have a cause, because there was no time for a cause to exist in. For… — Stephen Hawking Copy Share Image
At times, I get very lonely because people are afraid to talk to me or don't wait for me to write a… — Stephen Hawking Copy Share Image
We lived in a tall, narrow Victorian house, which my parents had bought very cheaply during the war, when everyone thought London… — Stephen Hawking Copy Share Image
The doctor who diagnosed me with ALS, or motor neuron disease, told me that it would kill me in two or three years. — Stephen Hawking Copy Share
The human race does not have a very good record of intelligent behavior. — Stephen Hawking Copy Share
“We have finally found something that doesn’t have a cause, because there was no time for a cause to exist in. For me this… — Stephen Hawking Copy Share
[On President Bush's plan to get to Mars in 10 years] Stupid. Robots would do a better job and be much cheaper because you… — Stephen Hawking Copy Share
I believe the simplest explanation is, there is no God. No one created the universe and no one directs our fate. This leads me… — Stephen Hawking Copy Share
The increase of disorder or entropy is what distinguishes the past from the future, giving a direction to time. — Stephen Hawking Copy Share
Most sets of values would give rise to universes that, although they might be very beautiful, would contain no one able to wonder at… — Stephen Hawking Copy Share
There is a fundamental difference between religion, which is based on authority, and science, which is based on observation and reason. Science will win… — Stephen Hawking Copy Share
“In the eighteenth century, philosophers considered the whole of human knowledge, including science, to be their field and discussed questions such as: Did the… — Stephen Hawking Copy Share
A model is a good model if first it interprets a wide range of observations in terms of a simple and elegant model, and… — Stephen Hawking Copy Share
