Is There a Simple Proof For a Vast Multiverse?
Season 11
Episode 10

Weinberg was foundational in establishing the standard model of particle physics, but his little 1987 paper, though more obscure, may tell us something about how the multiverse works, and can even be thought of as evidence for the existence of an enormous number of other universes.
