If the universe is ever expanding, what's beyond the universe?

Answer 1

Brian Green suggested thinking of it like this. Glue a number of pennies to a very large balloon and then infalte it. A tiny person on any penny would see the pennies accelerating away from him in all directions. Since the surface of the balloon is the only part of his universe that has any meaning (he cannot leave the surface or go into the interior of the balloon), he would conclude that the univserse is expanding at every point, with no point being special in any way.

Also, his universe (like ours), is finite, but without boundries, if he took a trip around the balloon, eh would wind back where he began, with no way (as a being in what is essentially a two-dimensional universe) to explain how this had happened.

Answer 2

Beyond our universe is an infinite space that contains absolutely nothing and it is this "nothingness" than our universe is expanding into.

Answer 3

other Universes shrinking at the same rate we're expanding.

Answer 4

Currently is space, there are 2 things taking up space.
1) Matter (&antimatter)
2) Space (nothing but still space)

I think something that is nothing AND non-space and not antimatter at the same time. Something where nothing can exist because there is no space. (no pun intended)
