ACTUALLY, the majority of existence is on the other side of the Source Wall!
This was literally what Slott did with The Barrens which was the destroyed nine-tenths. The Watchers put up a barrier at the edge of the universe to keep the rest out because it was that much of a wasteland after the Ultimate Nullifier was used, and at the end of the event Utau brings down the barrier.
It was dumb when DC did it, it was dumb when Slott copied it. But then Slott sucks in general so that's par for the course.
