I'm having trouble with this usage of the world "universe". Can't you call it "timeline" or "plane" or something?

No, because that's not at all what I mean. What I mean is much closer to "mathematical structure", but potentially much wider, up to and including logical impossibilities and the like.

I think my brain just quit on me. I'm asking it to come back and not be scared, but I'll need some help here. Could you present this in more palatable terms, and in more detail? Examples are good; my brain is much better at inference than deduction.

Being scared shitless is a perfectly normal and justified reaction. Quick examples don't really work, but I do recommend reading Permutation City, which handles some of these issues, but not the more exotic ones.

Hm. The only thing I know about Perm City is that there's this guy who keeps building chair legs. Over and over. EY seems to think it's a sad fate.
