The discussion explores the concept of multiple universes, drawing analogies to solar systems and galaxies. Participants consider terminology, definitions, and implications of having more than one universe, touching on theoretical and conceptual aspects.
Participants express differing views on the definition of "universe" and whether multiple universes can exist. There is no consensus on terminology or the implications of having multiple universes.
Discussions include assumptions about the nature of universes and the implications of physical laws, but these remain unresolved. The definitions and boundaries of what constitutes a universe are also debated without clear conclusions.

If there were many universes like there are solar systems in a galaxy and like there are many galaxies in the universe, What would you call it?

A term already coined for this is "multi-verse".

Actually, I think Multiverse is being used specifically as the term that describes the different Universes produced by Schrödinger's Cat effect.
As far as there being may Universes, much like there are many solar systems, galaxies, etc... I say it's not possible, since "Universe" means "everything" or "all that exists", and you can't have more than one of those.

I'd say that if the same physics laws work there, it's still our universe. I'd define another universe as one where the same laws do not work.
And I'd call it the parauniverse... :):)
