I’m not sure if the death of the multi-verse theory described in this obituary is correct, or if correct, whether that kills off the possibility of any other universe (shy of all the layers of the multi-verse).  I’m also not convinced that “other universe” is an adequate synonym for “alternate plane of reality” even though we use the former phrase to mean the latter all the time. If these two concepts are not identical, then having no other universes would not necessarily be problematic for those who post ETs are from another dimension, or those Christians who opt for aliens as “spiritual entities” (demons for the most part; note that the “spiritual world” needs to be another plane of reality).  Perhaps there are several reality planes within our single universe – ? Or maybe the problem is *this particular theory* of the multi-verse.

Any thoughts on the terminology problem or the general issue?
