A measure of the multiverse
arXiv:hep-th/0609193 · doi:10.1088/1751-8113/40/25/S22
Abstract
I review recent progress in defining a probability measure in the inflationary multiverse. General requirements for a satisfactory measure are formulated and recent proposals for the measure are clarified and discussed.
