Infinite Universe?
I have a question for the astrophysicists amongst us:

One of the primary arguments against an infinite universe is that if it were infinite, it would be filled with light from distant suns (It would be solid light instead of dark). I believe that the big bang created our local universe. What I am wondering is that is it possible that the forces released by the big bang were so incredibly powerful that they prevented light (photons) from these distant stars from entering into our "local" universe?

I realize that this may be a stupid question.

That seems to assume that light from elsewhere could enter our local universe - that would make our universe not local.

Skepticism is not a position; it is an approach to claims.

Not an astrophysicist, but it would seem if a universe has curved space-time then any light would be within its space-time realm. We wouldn't be able to see anything outside of it.

If the universe were infinite and traversable, there would be an infinite number of alien lifeforms arriving at your house at all times.

Or something...

Are you asking about Olbers' Paradox?

Essentially, he (?) is. But that only holds if we're assuming present observable conditions to extend infinitely in space and time.

And we already know that that's not the case. The observable universe has a horizon and a clear starting point and history.

... this is my signature!

I didn't realize it, but, yes, I am.

Maybe "local" is not the right term. I meant the universe that we can observe.

Is it possible, then, for other universes to exist outside of our own (within an infinite universe).

That would be true only if it were traversable.
