interesting, but no i dont think its a hyper sphere
Why not? Its a nice idea ... actually it might be a pretty good explanation of all the controversy around expansion / contraction etc... of the universe.
Though, since our event horizon (the furthest that light has reached, thus the furthest we can see into space) is relatively small compared to the universe -- I doubt scientists would be looking back at our own galaxy billions of years ago.
The only thing is, is it consistent with general relatively? Is a hypersphere even mathematically possible?
