The multiverse theory is, in my opinion, a mathematical construct with no basis in reality. The suggestion that there may be a huge number of ‘parallel’ universes is uneconomic, and absurdly extravagant, especially in light of the fact that we see before us only one universe, and that no empirical evidence whatever supports the existence of any others. I’m more comfortable with the possibility that multiple universes exist only as superpositions of an unresolved quantum reality, and that, for reasons we may not understand, our singular universe is the one which has precipitated from an infinitely large number of possible (but unrealized) formulations.

How do zero-mass black holes form?
