Robert J. Marks on why there cannot be an infinite number of universes
The Big Bang Theory sitcom’s Sheldon Cooper insists that in no universe would he dance with Penny.

Even if there were, Cantor’s theory of the infinite shows that, if there were an infinite number of contingencies, not all contingency combinations could be accounted for by an infinite number of universes.
