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.
Spherical? We don’t know if the universe is of finite size.
As far as we know, it could just as well be infinite, and the expansion happens everywhere.
Everything is relative so the only thing we know is that the distance between galaxies increases. But we don’t know if there’s a “border” of the universe or not.
