Phys. Rev. Lett. 97, 191302 (2006) [4 pages]Holographic Probabilities in Eternal InflationReceived 8 June 2006; published 6 November 2006 In the global description of eternal inflation, probabilities for vacua are notoriously ambiguous. The local point of view is preferred by holography and naturally picks out a simple probability measure. It is insensitive to large expansion factors or lifetimes and so resolves a recently noted paradox. Any cosmological measure must be complemented with the probability for observers to emerge in a given vacuum. In lieu of anthropic criteria, I propose to estimate this by the entropy that can be produced in a local patch. This allows for prior-free predictions. © 2006 The American Physical Society URL:
