Stephen Hawking Quotes

Physics grapples with the largest questions the universe presents. 'Where did the totality of reality come from?' 'Did time have a beginning?'

About the 50th hour, I was going to start thinking about the edge of the universe. Is there an edge? Is this an envelope we're living inside of, or no, does it go onto infinity in both time and space? And there's nothing like swimming for 50 hours in the ocean that gets you thinking about things like this.

When we understand string theory, we will know how the universe began. It won't have much effect on how we live, but it is important to understand where we come from and what we can expect to find as we explore.

And what we know, or think we know, about the universe of space and time is changing very quickly.

The universe never did make sense; I suspect it was built on government contract.

The limitless content of our universe might be only one instance of a large (and possibly infinite) number of other universes.

People have contemplated the origin and evolution of the universe since before the time of Aristotle. Very recently, the era of speculation has given way to a time of science.

At the same time, new concepts and abstractions flow into the picture, taking up the task of describing the universe without reference to such time or space - abstractions for which our language lacks adequate terms.

For most people, the major hurdle in grasping modern insights into the nature of the universe is that these developments are usually phrased using mathematics.

Evolutionary cosmology formulates theories in which a universe is capable of giving rise to and generating future universes out of itself, within black holes or whatever.

Most gravity has no known origin. Is it some exotic particle? Nobody knows. Is dark energy responsible for expansion of the universe? Nobody knows.

Why is there space rather than no space? Why is space three-dimensional? Why is space big? We have a lot of room to move around in. How come it's not tiny? We have no consensus about these things. We're still exploring them.

The word 'universe' is obviously not intended to have a plural, but science has evolved in such a way that we need a plural noun for something similar to what we ordinarily call our universe.

Philosophically, the universe has really never made things in ones. The Earth is special and everything else is different? No, we've got seven other planets. The sun? No, the sun is one of those dots in the night sky. The Milky Way? No, it's one of a hundred billion galaxies. And the universe - maybe it's countless other universes.

According to 'M' theory, ours is not the only universe. Instead, 'M' theory predicts that a great many universes were created out of nothing.

Heisenberg, Max Plank and Einstein, they all agreed that science could not solve the mystery of the universe.

It is rather fantastic to realize that the laws of physics can describe how everything was created in a random quantum fluctuation out of nothing, and how over the course of 15 billion years, matter could organize in such complex ways that we have human beings sitting here, talking, doing things intentionally.

One of the weird things about modern physics is that we do find there are apparently these other dimensions that we don't directly experience that explain some aspects of the overall geometry and reality of our universe.

Although we don't know what is outside our universe, astronomers still wonder. Several pictures of what there might be have been dreamed up. An interesting one, called multiverse, has lots of universes. Picture it as a foam of bubbles. Our universe would be one bubble, and we'd be surrounded by lots of other bubbles.

I think my proper response is complete amazement and awe at the universe that we are in, and how it works is just far more complicated than humans will ever properly understand.

The beauty of science is to imagine more than we can prove. And string theory gives you a radically different interpretation of the universe.

I would like to uncover the secrets of the universe.

I like science fiction and physics, things like that. Planets being sucked into black holes, and the various vortexes that create possibility, and what happens on the other side of the black hole. To me it's the microcosmic study of the macrocosmic universe in man, and that's why I'm attracted to it.

It now appears that the way the universe began can indeed be determined, using imaginary time.

From a scientific point of view, our mission is to seek answers to the fundamental questions about the universe. Many are open - we don't know about dark matter, which accounts for a quarter of the universe's matter, nor do we know why there's antimatter.
