Stationary Measure in the Multiverse

TL;DR

This paper evaluates the stationary measure in the string landscape, showing it avoids common paradoxes and effectively predicts local experimental outcomes like proton decay.

Contribution

It demonstrates that the stationary measure avoids the Boltzmann brain problem and the youngness paradox, and accurately predicts local experimental results.

Findings

Does not suffer from Boltzmann brain problem

Avoids the youngness paradox

Successfully predicts local experiment outcomes

Abstract

We study the recently proposed "stationary measure" in the context of the string landscape scenario. We show that it suffers neither from the "Boltzmann brain" problem nor from the "youngness" paradox that makes some other measures predict a high CMB temperature at present. We also demonstrate a satisfactory performance of this measure in predicting the results of local experiments, such as proton decay.
