My goal is simple. It is a complete understanding of the universe, why it is as it is and why it exists at all
Stephen Hawking

 

The mass of the sun curves space-time in such a way that although the earth follows a straight path in four-dimensional space-time, it appears to us to move along a circular orbit in three-dimensional space.
Stephen Hawking

 

Common sense is just another name for the prejudices we've been taught all our lives

Stephen Hawking

 

The usual approach of science of constructing a mathematical model cannot answer the questions of why there should be a universe for the model to describe. Why does the universe go to all the bother of existing?

Stephen Hawking

 

The nearest star, called Proxima Centauri, is found to be about four light-years away, or about twenty-three million million miles. Most of the other stars that are visible to the naked eye lie within a few hundred light-years of us. ³⁷
Stephen Hawking

 

The whole history of science has been the gradual realization that events do not happen in an arbitrary manner, but that they reflect a certain underlying order, which may or may not be divinely inspired
Stephen Hawking

 

We now know that our galaxy is only one of some hundred thousand million that can be seen using modern telescopes, each galaxy itself containing some hundred thousand million stars... We live in a galaxy that is about one hundred thousand light-years across and is slowly rotating; the stars in its spiral arms orbit around its center about once every several hundred million years. ³⁸
Stephen Hawking

 

We are just an advanced breed of monkeys on a minor planet of a very average star. But we can understand the Universe. That makes us something very special
Stephen Hawking

 

There is no prescribed route to follow to arrive at a new idea. You have to make the intuitive leap. But the difference is that once you've made that intuitive leap you have to justify it by filling in the intermediate steps

Stephen Hawking

 

Newton, and others, should have realized that a static universe would soon start to contract under the influence of gravity. But suppose instead the universe expanding. If it was expanding fairly slowly, the force of gravity would cause it eventually to stop expanding and then to start contracting. However, if it was expanding at more than a certain critical rate, gravity would never be strong enough to stop it, and the universe would continue to expand forever.
Stephen Hawking
