Expansion of the Universe Quotes

In the beginning the Universe was created. This has made a lot of people very angry and been widely regarded as a bad move.

I am deeply impressed with the way dark matter has explained cosmological observations.

How can a speck of a universe be physically identical to the great expanse we view in the heavens above?

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.

Because there is a law such as gravity, the universe can and will create itself from nothing.

I think it's amazing that the entire community of astronomy has done what it's done. We've been able to deduce the nature of time and space and where we all came from. It's the most amazing detective story in history.

A universe that came from nothing in the big bang will disappear into nothing at the big crunch. Its glorious few zillion years of existence not even a memory.

The success of ordinary cosmology speaks against the idea that the universe was created in a random fluctuation.

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

Radio Astronomy has added greatly to our understanding of the structure and dynamics of the universe. The cosmic microwave background radiation, considered a relic of the explosion at the beginning of the universe some 18 billion years ago, is one of the most powerful aids in determining these features of the universe.

As soon as the idea of the Big Bang was proposed in the 1920s, astronomers set about trying to work out when the bang happened. Initial estimates were, not surprisingly, wildly inaccurate, but by the 1980s it was known that the universe was 15 billion years old, give or take 5 billion years.

It seemed like my favourite kind of job - a wonderful chance to ask something absolutely fundamental: the fate of the Universe and whether the Universe was infinite or not.

We have a remarkably complete picture in many ways - and it could be that we're not accounting for something that's almost three-quarters of the entire universe.

There is nothing bigger or older than the universe.

Until the 1990s, there were few reliable observations about movement at the scale of the entire universe, which is the only scale dark energy effects. So dark energy could not be seen until we could measure things very, very far away.

They've discovered that, where all the other galaxies are moving in one direction, ours is going in another. Now, the Big Bang theory says that we're all moving outward.

Scientists - who prefer explanations subject to laboratory tests - figure that everything we see today was as inevitable as wrinkles, once the Big Bang established physics. Stars and planets were cooked up as huge clouds of matter collapsed and coalesced.

The Big Bang theory is the idea that if we go back early enough in the history of the universe - and we can do this, of course, by looking at starlight coming to us from billions of years ago - we will see a very hot and dense period where the universe was much smaller, denser, and hotter.

Hubble has really opened our eyes to what the universe is made of, its structure, and has helped us learn how little we know about the universe.

I've been working in cosmology since 1964.

We know very little about the universe. I personally don't believe it's uniform and the same everywhere. That's like saying the earth is flat.

I'm baffled all the time. We don't know what's driving 96% of the universe. Everybody you know and love and heard of and think about and see in the night sky through a telescope: four percent of the universe.

One of the great challenges of modern cosmology is to discover what the geometry of the universe really is.

We look at distant exploding stars called supernovae, and we've developed techniques to measure how far away they are and how fast they're moving away from us.

It's everywhere, really. It's between the galaxies. It is in this room. We believe that everywhere that you have space, empty space, that you cannot avoid having some of this dark energy.
