“In space, no one can you scream; an in a black hole, no one can see you disappear” — Stephen Hawking Copy Share Image
Think of our DNA. In the last million years, our DNA hasn't changed at all. It's really much the same as it… — 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
Bodies like the earth are not made to move on curved orbits by a force called gravity; instead, they follow the nearest… — Stephen Hawking Copy Share Image
Our population and our use of the finite resources of planet Earth are growing exponentially, along with our technical ability to change… — Stephen Hawking Copy Share Image
It surprises me how disinterested we are today about things like physics, space, the universe and philosophy of our existence, our purpose,… — Stephen Hawking Copy Share Image
I don't think the human race will survive the next thousand years, unless we spread into space. There are too many accidents… — Stephen Hawking Copy Share Image
I have wanted to fly into space for many years, but never imagined it would really be feasible. — Stephen Hawking Copy Share Image
Gravity is so strong that space is bent round onto itself, making it rather like the surface of the earth. If one… — Stephen Hawking Copy Share Image
Please join me in applauding the ESA - European Space Agency’s historic efforts with the Rosetta Mission and landing a spacecraft on… — Stephen Hawking Copy Share Image
If we can avoid disaster for the next two centuries, our species should be safe as we spread into space. If we… — Stephen Hawking Copy Share Image
Before 1915, space and time were thought of as a fixed arena in which events took place, but which was not affected… — 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
