We learned that it's accelerating.

So we say the universe is expanding.

The universe is expanding for the last 10 billion years or so.

For one thing, the universe will expand forever.

Then it was discovered that the universe was expanding.

He didn't know about the Big Bang. He didn't know about the expansion of the universe.

Back when I was your age, we didn't know what the universe was going to do.

Or larger, what's the role of dark matter in the expansion of the universe?

Because dark energy, unlike matter or radiation, does not dilute away as the universe expands.

And at that point, the universe mysteriously starts accelerating its expansion and cuts off the formation of larger scale structure.

And it keeps forming until the universe is roughly about half the size it is now, in terms of its expansion.

Individual galaxies are speeding away from us faster and faster so we say the universe is accelerating.

But if there's dark energy, and the dark energy does not go away, the universe is just going to keep expanding forever and ever and ever.

Space may be finite or infinite, but because the universe is accelerating, there are parts of it we cannot see and never will see.

As a result, the cosmological term that has been reinstated to account for the new observations is not quite the one that Einstein proposed and retracted. It is larger, for it now has to explain not just why the universe isn t collapsing, but why its expansion is accelerating.

(c) Twelve satellites from the Cosmos series (Cosmos 2337 to Cosmos 2348)

17 artificial Earth satellites from the Cosmos series (Cosmos 2306 to Cosmos 2322)

Eight artificial Earth satellites from the Cosmos series (Cosmos 2327 to Cosmos 2334)

And we go through a period of accelerating expansion, and the universe expands and cools until it gets to the point where it becomes transparent, then to the Dark Ages, and then the first stars turn on, and they evolve into galaxies, and then later they get to the more expansive galaxies.

The standard explanation is that the universe somehow sprang into existence, full of a strange kind of energy inflationary energy which blew it up.

I'm going to show you a movie simulation 16 powers of 10 faster than real time, which shows a patch of the universe where the expansions have subtracted out.

7 March three satellites (Cosmos 2307 to Cosmos 2309) and

24 July three satellites (Cosmos 2316 to Cosmos 2318).

In December 2004, GLONASS gained three more satellites Cosmos 2411, Cosmos 2412 and Cosmos 2413.

And then suddenly, bang! A universe appears, an entire universe.

Cosmic Strings

Maybe the universe comes out of a universal chicken.

It was cosmic radiation left over from the very birth of the universe.

Unlike the occupants of the universe, the universe itself is not wasteful.

The story of whyEinstein proposed the cosmological term, whyhe dropped it, and whycosmologists today have reintroduced it illustrates this process. Einstein sought to avoid the implication of unmodified general relativity that the universe cannot be static that it can expand (slowing down, against its own gravity), collapse, or be instantaneously at rest, but that it cannot hang unsupported.

The universe is in our mind, and our minds are in the universe.

How did the universe come into being?

Parallel universes.

Upwards to the space!

Somehow, 13 billion years ago there was a Big Bang, and you've heard a little bit about, you know, the origin of the universe.

Here is the universe that we tell you about, versus the universe that really exists.

And if we kind of ponder on that, then perhaps cymatics had an influence on the formation of the universe itself.

Because our home is the universe, and we are the universe, essentially.

OXFORD It was recently discovered that the universe s expansion is accelerating, not slowing, as was previously thought. Light from distant exploding stars revealed that an unknown force (dubbed dark energy ) more than outweighs gravity on cosmological scales.

The universe is really big.

The universe is a contradiction.

...and immensity of our universe.

If the universe is not a fluctuation, why did the early universe have a low entropy?
