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?

You are the center of the universe. A star, 2 billion light years away is also at the center of the universe.
Everything that is everywhere originated from the same infinitesimally small point that stretched out in to the universe we observe today. It’s not like a grenade going off, where you can point to a center and an edge. It’s more like proofing dough.
IF that is true, that means any “edge” to the universe must also exist at it’s center, and therefore be surrounded on all sides by the universe. It would look more like a 3 dimensional hole than a bubble we’re inside of.
Hmm. Does it make sense to say that two different points are the center? We can’t all be the center if we’re in different positions. In this case it makes more sense to me to say that there is no center. No?
