If we lived in a multiverse, what would our universe most likely then be named? We live in the Milky Way Galaxy, but we don't just call it &quot;The Galaxy&quot;, 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 &quot;The Universe&quot;.
How are names for things like this created, and what would a likely name for our universe be?
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.
