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?

My theory is that the universe is a higher form of a sphere. If you travel along a straight line long enough, you end up in the same place you started.
On what do you base this theory of yours?
Nature is fractal/reflectve (leaf veins look like branches look like trees). Circles are a repeating motif in the universe. Planets and other bodies like stars are spherical. They travel in circular orbits. Bubbles expand uniformly, like the universe.
When you travel in circles and spheres you end up in the same place but it feels infinite/no beginning no end — like the universe. Ever expanding no beginning no end.
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.
