Thus the term “observable universe”. Everything beyond our observable universe is being expanded away from us at faster than the speed of light, so nothing outside will ever reach us. Causality is completely and irrevocably severed at those distances so, arguably, anything outside the observable universe is not part of “our” universe.
My point is, it doesn’t reveal anything about the nature of the universe only about the limited view we can observe. As far as form goes the form of a sphere is meaningless because it is true of anything in a 3d space that is looking out from a fixed point.
