For instance, we live in the Milky Way Galaxy. We don't just call it "The Galaxy", because we know there are multiple different galaxies. So if we lived in a multiverse, it wouldn't make much sense to keep calling our universe "The Universe".

How are names for things like this created, and what would a likely name for our universe be?

Many good questions generate some degree of opinion based on expert experience, but answers to this question will tend to be almost entirely based on opinions, rather than facts, references, or specific expertise.If this question can be reworded to fit the rules in the help center, please edit the question.

@Rhys, very reasonable and good question. If questions whether pluto is a planet and alike are discussed at IAU meetings, why would it be unreasonable to speculate on the possible names for our part of the multiverse? –  Alexey Bobrick Feb 23 at 14:26
    
@AlexeyBobrick predominantly because we try to avoid things that are mainly speculation as it does not lead to constructive, source verified answers. Though I am willing to concede that I make mistakes, if the community votes to reopen then I will happily oblige –  RhysW Feb 24 at 21:48
    
@AlexeyBobrick I reclosed with hopefully a more clear close reason. I wouldn't exactly say it is off topic, but we have no reliable methodology for determining what the IAU might name our universe, especially since names for unique items in a set are usually derived from features which distinguish them from other items in the set. Since we do not know what other universes are like (if they exist), this leaves us with really nothing to work with. –  called2voyage Feb 25 at 16:30

New objects usually get some preliminary name or number according to one or more naming or numbering conventions (e.g. HR numbers for stars). If there aren't too many objects of interest, they are named by the discoverer(s) (e.g. Hubble volume), an institution (e.g. PANSTARRS), an occasional nickname liked by the public (e.g. black hole), or by a majority in a commitee or an election (e.g. Hydra).

For our universe I can only speculate; probably a notion of the respective multiverse theory would become part of the name, e.g. "Herman brane", if we take a brane cosmology as an example.
