Universe Expansion Quotes

Only two things are infinite, the universe and human stupidity, and I'm not sure about the former.

The universe is very large, and its boundaries are not known very well, but it is still possible to define some kind of a radius to be associated with it.

There are two things that are infinite: The universe and human folly. And sometimes I am not sure about the universe.

If the rate of expansion one second after the Big Bang had been smaller by even one part in a hundred thousand million million, it would have recollapsed before it reached its present size. On the other hand, if it had been greater by a part in a million, the universe would have expanded too rapidly for stars and planets to form.

Dark energy is incredibly strange, but actually it makes sense to me that it went unnoticed, because dark energy has no effect on daily life, or even inside our solar system.

In the far, far future, essentially all matter will have returned to energy. But because of the enormous expansion of space, this energy will be spread so thinly that it will hardly ever convert back to even the lightest particles of matter. Instead, a faint mist of light will fall for eternity through an ever colder and quieter cosmos.

One of the most exciting things about dark energy is that it seems to live at the very nexus of two of our most successful theories of physics: quantum mechanics, which explains the physics of the small, and Einstein's Theory of General Relativity, which explains the physics of the large, including gravity.

We've gotta become the Martians. I'm a Martian - I tell you to become Martians. And we've gotta go to Mars and civilize Mars and build a whole civilization on Mars and then move out, 300 years from now into the universe. And when we do that, we have a chance of living forever.

We will build new ships to carry man forward into the universe, to gain a new foothold on the moon and to prepare for new journeys to the worlds beyond our own.

Game creation keeps on expanding, just like the Universe. That is why I keep making games

The universe will finally become a ball of radiation, becoming more and more rarified and passing into longer and longer wave-lengths. The longest waves of radiation are Hertzian waves of the kind used in broadcasting. About every 1500 million years this ball of radio waves will double in diameter; and it will go on expanding in geometrical progression for ever. Perhaps then I may describe the end of the physical world as-one stupendous broadcast.

I cannot possibly conceive of my planet Earth as the centre of a three-tiered universe. I know rather that the sun, around which my planet Earth revolves, is a middle sized star in a galaxy called the Milky Way that has over a hundred billion other suns or stars within it.

I can feel the universe expanding and making things be further apart.

The gravitational constant, if it were off by one part in a hundred million million, then the expansion of the universe after the Big Bang would not have occurred in the fashion that was necessary for life to occur. When you look at that evidence, it is very difficult to adopt the view that this was just chance.

We need to spread out now in the universe. I think in 100 years we'll be living on other planets.

If you're puzzled by what dark energy is, you're in good company.

We may, perhaps, imagine that the creation was finished long ago. But that would be quite wrong. It continues still more magnificently, and at the highest levels of the world.

When you buy a jacket, you pick the size to ensure it fits. Similarly, we live in a universe in which the amount of dark energy fits our biological make-up. If the amount of dark energy were substantially different from what we've measured, the environmental conditions would be inhospitable to our form of life.

Pure science - this vision of the universe as 15 billion light years across - I am bedazzled and awed by it.

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.

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.

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!

Out of all the ridiculous religion stories - which are greatly, wonderfully ridiculous - the silliest one I've ever heard is, 'Yeah, there's this big, giant universe, and it's expanding, and it's all going to collapse on itself, and we're all just here, just 'cuz. Just 'cuz.' That to me, is the most ridiculous explanation ever.

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.

The immensity of the universe didn’t suddenly change, but our ability to see and understand this truth changed dramatically. And with that greater light, mankind was introduced to glorious vistas we had never before imagined.
