Since you guys keep posting about conners and getting no where with this thoery im going to share some info, logic and idea on your theory.
I've currently tested this a few times and have no produce any evidence that there is muli worlds.
I've followed the rim.
I've made alts and sent em' throw vortex only to find the alt a few maps away.
BUT in logic means. J&L are putting in seasons. loftar old idea was bad. but I can see with muli worlds. as being a good fix to his old (time) idea.

if there is currently 2 multi worlds.
it likely very hard to cross over with only 1% chance with a vortex.
Likely also IP locked so that you only spawn in the same world with alts.
if someone going to prove multi worlds
then stop posting corners.
the world is a diamond, you're welcome.
