It really seems you need to taboo "real" here, and instead ask some related questions such as:
which types of universes could observe which other types of universe (an universe which can observe you you can also, obviously, "travel" to)? Which universes could trade, in the broadest senses of the word, with which other universe? What types of creatures in which types of universes are capable of consistently caring about things in what types of universes?
Specifically it seems likely that your usage of "real" in this case refers to "things that humans could possibly, directly or indirectly, in principle care about at all.", which is the class of universes we must make sure to include in our priors for where we are.
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.
