Hmm obvious but non-intuitive realization about individual universes within multiverses: they cannot have names/addresses like “Earth C137 in central finite curve” (our world in Rick and Morty multiverse) to inhabitants who aren’t multiverse travelers. They have to be unaware

It’s worse than that. If you think about it seriously there is the cardinality issue (finite, countable, uncountable). There is the geometry issue (why should the topology, ie the “nearness” be 1, or 2, or N-dimensional).

Isn't this kind of always true for locations of any kind? If all you've known in life is a single village, and you don't know other villages exist, would it have a name?
