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?

Maybe it would be more accurate to say that the universe is an ellipse? Since most orbits and planets and stars are not actually circles or spheres.
Still though, just because many things are elliptical doesn’t mean the universe is.
But it might be! Would be super cool.
