Well I was thinking, space (in the human abstraction) is the paradigm that there is space between two different objects creating the conception of there is quantity for things to be separated by location and event. Since spacetime quantity outside of the universe doesn't exist, how can there be more than one universe? Is spacetime then a fabric outside our universe in which our universe takes a grasp of? What difference does that make? That just means all the universes are existing inside another super "universe". People say that this inflated world is infinite with super spacetime. I don't see how that's possible since there was a "time" in which "each" universe was created.

If you're talking about this idea in the context of cosmic inflation, then the answer is fairly simple: the visible universe is not the Universe. Not the entirety of it, anyway. What we know as the universe would merely be a pocket of a much larger Universe, a bubble in a far greater sea. Thinking in terms of there being "more than one universe" or "spacetime outside of the universe" makes the idea needlessly complicated, in that those phrases don't quite accurately capture what's going on. It might be helpful to think of it merely as reconsidering what we define as "the universe"--is it everything we see out to the furthest quasar or could it be far more expansive than that?

You mean other sub-space domains?

Then if our universe is an entity simply inside another universe, where is "the Universe" since it has spacetime for our universe to expand into, what does "the Universe" have in position inside spacetime?" A multiverse theory would simply make it more complicated and meaningless therefore.

So what about pocket universes? Oh and since every galaxy has a black hole at it's center just where is the other end? Is there a universe with white holes spewing matter into it?
