The BB didn't expand "into" anything (in the way you're suggesting). Space(-time) itself is what was expanding, not just the matter in it. It doesn't make sense to describe it as expanding "into" something.
Getting back to this for a moment, could it not be that a void surrounded the BB which was not comprised of spacetime but rather was a simple void which had no characteristics or properties? Could multiple universes be "housed", surrounded in a void soup of sorts? It outwardly seems to me that the existance of a void of this sort could never be proven or disproven.

I love this thread, very interesting!
