How many universes are necessary for an ice cream to melt?

Abstract

We investigate a quantitative consequence of the Acausal-Anthropic approach to solving the long-standing puzzle of the thermo dynamical arrow of time. Notably, the size of the required multiverse is estimated on the basis of the classical Boltzmann connection between entropy and probability, as well as the thermodynamic properties of black holes.
