if the universe is expanding.?

Question

The univers is expanding at the speed of light at the point of origen there must surely be a void created as matter is no longer being produced from the initial "BIG BANG" and as matter is being spread more thinly over time and space will the universe go on for ever or will it end not with a reversal of events through gravity or keep expanding into infiity until all light matter is extiguised and only dark matter remains.

Answer 1

I agree that the universe is expanding at an exponential rate in certain areas, but the are also areas on the outer reaches that are actually regressing, which suggests that there might be a series of universes and that we are just filling and consuming space that is unattained by the others.

As released by NASA's finest they suggest that this theory of a multi-verse is very possible due to the fact of very little fact proving the 'BIG BANG'. I can also say that yes at the current rate of expanding it will eventually end up being only molecules and dark matter remaining (due to metric expansion), but the fact points towards the rate of expanding slowing over a period of time "billions of years". It has already slowed down, just not significantly enough to be fully recognised.

Answer 2

Taking into account that the big bang theory is true, at the beginning the whole universe -including time and space- was compressed into a very little "thing". All the matter was there, and it keeps expanding since there, without additional creation of new substance at the point of origin. As the universe keeps expanding, the existent matter will be spreading more and more, until... we can't be sure of what's next. Actually, there are no evidence that supports the "Big crush" theory, and at this time the universe keeps expanding. There won't be a void of dark matter, but surely it will be a lot of empty spaces

Answer 3

space is a void, matter isn't created anywhere in the universe at the centre or eleswhere, no the universe is not expanding at the speed of light because matter has mass and cannot move at the speed of light.
Many ideas exist about end universe one is a big freeze where every partitical stops moving due to a lack of energy and others are colapeses due to gravity.
what is light matter besides matter cannot be destroyed so it will always remain in some form

Answer 4

Just because the universe is expanding does NOT mean there was a 'big bang'....in fact, we now know that the universe's is expanding at an accelerating rate and there is no way to explain that by postulating a 'big bang'.

Btw, it is not expanding at the speed of light.

Answer 5

The universe is only expanding because the void in understanding is...

Answer 6

YES. The universe is expanding AND accelerating!

Answer 7

listen my children we are in the garden of Eden man has destroyed the original concept look around we are the only living sell in this universe please ask your self why are we alone we are not here by chance do you think that the big Odin is going to let us all be destroyed my only worry is that the big bulb in the sky is going to go bang or worse still the electric might run out all the stars are still there its only the pollution that stops us from seeing them scientist don't we just love them enough said from the preacher man

Answer 8

No one is certain of anything in the grand scheme of the universe!

It is all theoretical, some books are accepted as fact by some however they are STILL theories, and in the case of religon, fiction

Answer 9

Simply put: It's not that kind of expansion.

Answer 10

And you think we know the answer to this on here. I think Einstein is dead and if he wasn't do you think he would be on Y/A's
