The discussion centers on the concept of multiple universes, often referred to as the "multiverse." Participants debate the implications of the term "universe," with Mentat asserting that it denotes "everything" and thus cannot have multiples. Jeff highlights that "multiverse" is specifically linked to phenomena like Schrödinger's Cat, while Tail proposes the term "parauniverse" for realms governed by different physical laws. Doctor Luz emphasizes that a universe must be a closed system, where events in one cannot affect another.
PREREQUISITESAnyone interested in theoretical physics, cosmology, or philosophy, particularly those exploring the nature of universes and the implications of the multiverse theory.

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... :):)

But what defines a universe? How can we define the universe limits?
