Interesting thought. I wonder, though, what makes those places separate from the universe? The universe including those other places, metaphysical and scientific, would be even bigger and more mind-boggling.
Well, you have to define the universe at some point, and the most common definition on people's minds it's "this thing which our galaxy is in". I would presume that common perceptions don't include such notions as "separate reality split-universes" and sets of multi-verses, and what have you.
