How many universes in the multiverse?


Talking about the multiverse created by eternal inflation here, versus the quantum mechanical Many Worlds multiverse.

The authors discuss the possibility that the primary constraint on the number of countable, distinguishable universes lies within the limitations of the observer to distinguish differences among universes versus the constraints on the numbers of universes allowed by the properties of the multiverse. In other words, the multiverse allows more universes than the differences observers would be able to distinguish and remember among these universes.
