What you described is called Continuum hypothesis[1]. Surprisingly it cannot be proven to be either true or false from(is independent of) ZFC set theory.

Indeed, and nowadays set theorists have rich experiences both in worlds where the Continuum Hypothesis holds and in worlds where it does not.

I tried to explain the resulting "multiverse philosophy" (not really related to the idea of physical alternate universes) here: https://iblech.gitlab.io/bb/multiverse.html
