What’s the Reality Behind Multiverses and Alternate Realities?
The idea of a multiverse rubs some members of the scientific community the wrong way. Multiverse theory is, by definition, unfalsifiable and outside the realm of experimentation. It flies in the face of the scientific method and therefore, some would argue, should be left to the realm of philosophy, not science. That being said, the case for the multiverse is not solely within the province of fantasy.
