"Did Scientists Actually Spot Evidence Of Another Universe?" (see here, and a recent arXiv paper)
There is a problem with that view, what does "other" really means. Since there are traces of "others" that can be detected, this suggests at least a "scheme" of laws that applies to "this" and all the "others" as well. Like a moduli space? In which case there is only one (albeit "generalized" of sorts) Universe.
