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?

This would mean black holes can contain black holes, since we have also observed them inside our own universe/black hole. Which means there can be infinite universes inside each other.
😳 This toilet session turned into something else for me.
Here’s another fun fact then, any “cosmic boundary” would be surrounded on all sides by the universe, and would simultaneously exist at it’s center. Because every point in the entire observable universe is the center of the universe.
Which again sounds an awful lot like a black hole.
So maybe there is a boundary. It’s all black holes all the way down. interconnected universes all pointing to each other through black holes and Einstein-Rosen bridges all feeding off of and in to one another. The dark energy accelerating space time’s expansion coming from beyond our local event horizon in a brief moment of feeding.
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.
