“Instead the idea that the universe is perhaps one of infinitely many is derived from current theories like quantum mechanics and string theory.”
This article is pop sci fluff. Yes, it’s based mainly on string theory, but string theory is not really a theory, under the scientific definition. It’s an untested (and probably untestable) hypothesis that isn’t based on any experiments or observation, but merely on some interesting mathematical artifacts that have been noticed.
