This isn't that new. There's long been speculation that our universe is like the inside (the eaten part) of a donut. Other "parallel" universes would be the same. It would even be possible for these universes to interlock without touching, forming a chain or loop. If they touch, that would be where travel could happen from one universe to another.

Last time I formally studied Math, it was established that there's nothing inconsistent with this theory, or contradictory to what we know.

The nice thing (or horrible?) about this is it's possible other universes aren't as far away as we assume.

We have pics of galaxies merging, and their aftermath.

Universes would be a ‘problem’...................
