Does space has end? If the answer is in the affirmative, the follow up question would be what goes beyond it?

Answer 1

No; it is unbounded. At first glance, if you were to travel 13.6 billion light years, you would reach the point at which the Big Bang occurred (you could go in any direction -- makes no difference). But it would take 13.6 billion years to do so, and by that time, the point is no longer there. Hence, we are in a cosmic Roach Motel: we have checked in, but we can't check out.

Answer 2

Questions involving the age, origin, and/or fundamental components of the "universe" (such as outer perimeter) are unaswerable, except by the ultimate implementation of blind faith. So pick the two cosmogenies you like the best, and flip a coin.

Personally, I favor the Biblical cosmology, but a supportive elaboration would be far too lengthy for this post.

Answer 3

You should look into reading "The Elegant Universe" It answers a ot of these sorts of questions in a very visual, easily understood way and it is a great piece. Sorry that's not much of an answer, I'm not very eloquent with these things.

Answer 4

your second question answers the first - space is inifite by definition

if you want a carzu theory, I think out space is on a 4-dimensional sphere, so if you keep going straight, you will just come back to where you started.

Answer 5

no it doesn't.
there's a possibility that space is looped, like the surface of a sphere, but in 3-dimentions... however modern astronomical data seems to favor it being infinitely long instead...

Answer 6

beyond that there is something that has no space and no time, some call that GOD

Answer 7

It probably curves back on itself so although it does not end it is limited
