Freak observers and the measure of the multiverse
Nov, 2006Citations per year
Abstract:
I suggest that the factor in the pocket-based measure of the multiverse, , should be interpreted as accounting for equilibrium de Sitter vacuum fluctuations, while the selection factor accounts for the number of observers that were formed due to non-equilibrium processes resulting from such fluctuations. I show that this formulation does not suffer from the problem of freak observers (also known as Boltzmann brains).- fluctuation: vacuum
- bubble: nucleation
- multiverse
- measure
