De Sitter Space Without Dynamical Quantum Fluctuations
We argue that, under certain plausible assumptions, de Sitter space settles into a quiescent vacuum in which there are no dynamical quantum fluctuations. Such fluctuations require either an evolving microstate, or time-dependent histories of out-of-equilibrium recording devices, which we argue are absent in stationary states. For a massive scalar field in a fixed de Sitter background, the cosmi...
متن کاملCan the Higgs Boson Save Us From the Menace of the Boltzmann Brains?
The standard ΛCDM model provides an excellent fit to current cosmological observations but suffers from a potentially serious Boltzmann Brain problem. If the universe enters a de Sitter vacuum phase that is truly eternal, there will be a finite temperature in empty space and corresponding thermal fluctuations. Among these fluctuations will be intelligent observers, as well as configurations tha...

Quantum fluctuations require time-dependent histories of out-of-equilibrium recording devices, which are absent in stationary states.

متن کاملWhy Boltzmann Brains Are Bad
Some modern cosmological models predict the appearance of Boltzmann Brains: observers who randomly fluctuate out of a thermal bath rather than naturally evolving from a low-entropy Big Bang. A theory in which most observers are of the Boltzmann Brain type is generally thought to be unacceptable, although opinions differ. I argue that such theories are indeed unacceptable: the real problem is wi...
متن کاملFreak observers and the measure of the multiverse
I suggest that the factor pj in the pocket-based measure of the multiverse, Pj = pjfj, should be interpreted as accounting for equilibrium de Sitter vacuum fluctuations, while the selection factor fj 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 obser...
