Again, though, doesn't that beg the question as to what exists OUTSIDE of the known universe? Is there nothing SOMEWHERE? Is it possible? (Somewhat serious question)

[RightWhale]

There is no outside. The universe is everything, although the geometry of the everything is in doubt.

It's all inside; there is no outside. It's like Stein's Okland: there's no there there.
