If the Universe in infinite?

Question

how can it be proven that it is expanding???

Answer 1

I've started to wonder if it's possible it's rotating around a center point possibly, maybe from our point of view we assume it's expanding.

Answer 2

According to my knowledge the universe is still expanding from The Big Bang. So therefore if you consider the universe being all the stars, planets, and matter created from The Big Bang then it is not infinite.
If you include what's beyond the expanding mass to be the universe too then it may well be infinite.

As no earthly object has been to the edge of the universe, nor actually witnessed The Big Bang, it's all best guess.

Make up you're own opinion. :)

Answer 3

I think you're quibbling over words. Technically, it is "space" that is infinite. the clusters of universes are basically innumerable by the human mind's comprehension - (perhaps?) - but would have a limited number at some point down that trail.

These scattered clusters of stars, planets and gases are expanding outward. While the Earth is not the central point of that expansion - calculations hypothesis were are not far from that point. I cant prove the Earth is dead center - but personally I think she is. But then I am getting off topic just a smidge, arent I.

Answer 4

The universe isn't infinite. If something is infinite, it can't be expanding - they're mutually exclusive ideas.

Answer 5

Physicists theorize that the universe is expanding because of the light radiating toward the earth that we see, is becoming either sightly lighter(other galaxies moving closer to ours) or slightly dimmer( other galaxies moving away from ours)........

Hope this helps :-)

Answer 6

It can't be. The expansion comes from a finite universe theory.
