Depending on where we look, the universe is expanding at different rates. Now, scientists using the James Webb and Hubble space telescopes have confirmed that the observation is not down to a measurement error.
The only thing spherical is the visible universe from earth that we can see. Both in time and distance. Due to the expansion of space that volume is increasing.
The entire universe could be infinite and take on any number of infinite shapes. Our local universe could be completely different from the rest of the universe and we’ll never be able to know…it’s wild.
Recent experiments trying to determine what the curvature of space-time is in the visible universe has concluded that it’s pretty much flat
But it’s entirely possible that we’re just on a very very very large (infinite?) curved surface of spacetime that just looks flat to us…

I would bet on it in fact. It makes logical sense to from my perspective.
