What does it even expand into like in terms of displacing the presumably “Nothing” that previously existed or didnt exist when the universe expanded and should have displaced or subsumed it?

If our universe exists inside a black hole, does that mean it would be potentially subject to collapse if “parent” black hole loses matter converted to energy and lost to the “parent universe” via Hawking radiation? Would this be our “big crunch”?
How do you know that isn’t already happening?
I don’t. I’m asking by applying what we know of physics in our universe, and assuming the same physics work in others (a big assumption I know). As in, I’m asking if my application is correct.
