Notice that Wells said that Earth-X wasn't counted because 'Who would ever go there?'

Perhaps there ARE infinite universes, but they're so messed up that no-one would ever want to go there, or they're simply unliveable, and only 52 of them are places you'd actually want to go.

Just a thought I had.
