All Possible Worlds?

I think I now see the role of the many universes hypothesis, assuming that these universes are linked at the quantum level, for given enough universes, all of them logically unique, temporally parallel, and finite in time, so that an infinite regress of the sort identified by the Kalam Argument is avoided, every logically possible universe can develop, our own universe being one of them.

I think that's what cosmologists like the late Stephen Hawking are getting at, though whether these cosmologists can get all the way to that "at" is the big question.
