Imaginary time is a new dimension, at right angles to ordinary, real time. — 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
Doing a job RIGHT the first time gets the job done. Doing the job WRONG fourteen times gives you job security. — Stephen Hawking Copy Share Image
The laws of science do not distinguish between the past and the future. — Stephen Hawking Copy Share Image
A picture is worth a thousand words...and uses up a thousand times the memory. — Stephen Hawking Copy Share Image
Up until the 1920s, everyone thought the universe was essentially static and unchanging in time. — Stephen Hawking Copy Share Image
“Each exists for but a short time, and in that time explore but a small part of the whole universe.” — 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
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
I believe that the long-term future of the human race must be space and that it represents an important life insurance for… — 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
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
So next time someone complains that you have made a mistake, tell him that may be a good thing. Because without imperfection,… — Stephen Hawking Copy Share Image
“if you take a positivist position, as I do, questions about reality don’t have any meaning. All one can ask is whether… — 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
“... if we do discover a complete theory, it should in time be understandable in broad principle by everyone, not just 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
“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
In A Brief History Of Time I used the word "God" like Einstein did as a shorthand for the laws of physics.… — Stephen Hawking Copy Share Image
Many people do not like the idea that time has a beginning, probably because it smacks of divine intervention. (The Catholic Church,… — Stephen Hawking Copy Share Image
When asked, 'What did God do before he created the universe?' St. Augustine didn´t reply, 'he was preparing Hell for people who… — Stephen Hawking Copy Share Image
One can imagine that God created the universe at literally any time in the past. On the other hand, if the universe… — Stephen Hawking Copy Share Image
This required abandoning the idea that there is a universal quantity called time that all clocks measure. Instead, everyone would have his… — Stephen Hawking Copy Share Image
The increase of disorder or entropy is what distinguishes the past from the future, giving a direction to time. — Stephen Hawking Copy Share Image
“Does general relativity predict that our universe should have had a big bang, a beginning of time?” — Stephen Hawking Copy Share Image
“If time travel were possible we'd be inundated with tourist from the future.” — Stephen Hawking Copy Share Image
It now appears that the way the universe began can indeed be determined, using imaginary time. — Stephen Hawking Copy Share Image
Disorder increases with time because we measure time in the direction in which disorder increases. — 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 Image
We are the product of quantum fluctuations in the very early universe. — Stephen Hawking Copy Share Image
The human race does not have a very good record of intelligent behavior. — 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 me this… — Stephen Hawking Copy Share Image
[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 Image
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 Image
The Paralympic Games is about transforming our perception of the world. — Stephen Hawking Copy Share Image
The increase of disorder or entropy is what distinguishes the past from the future, giving a direction to time. — Stephen Hawking Copy Share Image
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 Image
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 Image
“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 Image
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 Image
