There is only one Entire Universe; it's not a multiverse. And we observe it as a sphere, sized by the speed of light in every direction.
Trying to see beyond the edge would be like trying to peer out of a black hole. It would probably look blue, like Cherenkov radiation. (but I'm biased, due to having blue eyes).
If the Entire Universe is infinite, then it's eternal in time. And then we get philosophical again.

Most estimates put the Actual Universe as ~250x larger than the Observable Universe, if it is finite at all.
