The universe was opaque up to about 380,000 years after the Big Bang. If the universe loops in on itself and is large enough then wouldn't we be blocked by that

The universe was opaque up to about 380,000 years after the Big Bang. If the universe loops in on itself and is large enough then wouldn't we be blocked by that? And the further you go back from there the higher the density would be.
