We think not. The universe is currently conceived of as either infinite in size or as finite but boundless, meaning it has no edge or center, any more than the surface of the Earth can be considered to have an edge or center. The trick is that in a finite, boundless universe, the whole thing must come round to meet itself in a higher dimension (like a 4th spatial dimension outside the realm of our perception).

The English word "universe" means "everything that exists". So if there were a wall, then the wall and everything behind it would be part of the universe. Which means that the wall couldn't be at the end of the universe. So there can not be "a wall at the end of the universe".

As far as we know there is no wall. We can't really see to the end of the universe, though.

Some theories say that there are multiple universes, separated from each other by event horizons - you might call that a "wall."

No wall. No edge at all. Just like Earth has no edge.

Please don't look. That's where God goes when he has to go.
