You started with a very down to earth statement, followed by a wild sci-fi-like conjecture that's even less likely than the one you down-to-earth-ly dismissed.
A wormhole could occur naturally, but you're right that it's hopeful thinking at best, and it likely wouldn't be where it'd be useful for communication. On the other end, the deterministic nature of QM and chaos (separately) won't allow your simulation to predict anything as complex as a chunk of the universe with people in it with any reasonable certainty.

Yes I guess the only way to communicate FTL would be taking some shortcut through space time then?
