A Quote by Stephen Hawking

If it [the universe] 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.

The original project began because we know the universe is expanding. Everybody had assumed that gravity would slow down the expansion of the universe and everything would come to a halt and collapse. The big surprise was it was actually speeding up.

Observations indicate that the universe is expanding at an ever increasing rate. It will expand forever, getting emptier and darker.

Stephen Hawking

The universe is expanding, and every second that you're alive, the universe is bigger than it was a second before. There's nothing in front of us, exactly, other than the future, and there's no space for the size, the density of the universe to go. Because it's expanding at every point simultaneously.

Ariel Pink

If the universe is everything, and scientists say that the universe is expanding, what is it expanding into?

Steven Wright

The world has become a larger place. The universe has been expanding, and Perl's been expanding along with the universe.

Larry Wall

We've known for a long time that the universe is expanding. But about 15 years ago, my colleagues and I discovered that it is expanding faster and faster. That is, the universe is accelerating, and that was not expected, but it is now attributed to this mysterious stuff called dark energy which seems to make up about 70 percent of the universe.

Adam Riess

We would look up at the night sky together, and although Stephen wasn't actually very good at detecting constellations, he would tell me about the expanding universe and the possibility of it contracting again and describe a star collapsing in on itself to form a black hole in a way that was quite easy to understand.

Jane Hawking

One can imagine that God created the universe at literally any time in the past. On the other hand, if the universe is expanding, there may be physical reasons why there had to be a beginning. One could imagine that God created the universe at the instant of the big bang, or even afterwards in just such a way as to make it look as though there had been a big bang, but it would be meaningless to suppose that it was created before the big bang. An expanding universe does not preclude a creator, but it does place limits on when he might have carried out his job!

Stephen Hawking

Einstein wrestled with a problem back before we even knew the universe was expanding, and he was looking for a way to keep the universe from collapsing. And so he discovered, in his theory of gravity, something like this dark energy - he called it a cosmological constant - could play this role, pushing things away.

Adam Riess

For many artists the universe is expanding; for some it is contracting.

Robert Smithson

Observations indicate that the universe is expanding at an ever-increasing rate. It will expand forever, getting emptier and darker. Although the universe doesn’t have an end, it had a beginning in the Big Bang. One might ask what is before that but the answer is that there is nowhere before the Big Bang just as there is nowhere south of the South Pole.

Stephen Hawking

You might expect gravity would slow it down, but it's just expanding faster and faster.

Saul Perlmutter

If knowledge isn't self-knowledge it isn't doing much, mate. Is the universe expanding? Is it contracting? Is it standing on one leg and singing 'When Father Painted the Parlour'? Leave me out. I can expand my universe without you. 'She walks into beauty, like the night of cloudless climes and starry skies, and all that's best of dark and bright meet in her aspect and her eyes.

Tom Stoppard

You are not here to fix anything, because nothing is broken, but everything is continually changing and expanding. Release your struggle, and seek joy and fun, and in doing so, you will align with the fantastic expanding rhythm of this Universe.
