Category talk:Universes and dimensions

Why was this category created? Is there any distinction other than something being called a "universe" or "dimension," because those words are sometimes used interchangeably. And more pages would have to be relocated from "Other realities." That category seemed to cover everything pretty well, but I understand wanting to specify and categorize more.
