Earliest Dimension theory?

[Crodley]

Hi folks,

 

Got a science fiction story running through my head (they always run, they never seem to sit down on paper, heh) about other dimensions/alternate universes. But I want to set it back in time, perhaps the old west or so. My stumbling block is when did the idea of alternate universes first appear? Before the old shoot-em up days of the west or after?

 

I'm hoping you can adjust my fantasies appropriately. Thanks in advance.

Coeval "Other Worlds" have been a staple of human imagination for Milena, however any serious scientific thought on the matter wasn't done until the latter half of the Twentieth Century

Well, the thing I want is for my main character to explain to his apprentice about alternate universes and he can't very well do that if it wasn't known at that time...hmmm. (of course, since it's fantasy it doesn't have to be that accurate...but...) Latter part of the 20th too eh...darn can't make it a noir set in the 30's either, heh... My main problem is I need it to take place before the atom was split...

 

Ahh well. I'll keep working on it, thanks TONS for the info
