Cosmological measure with volume averaging and the vacuum energy problem

TL;DR

This paper proposes a volume averaging measure as a solution to the cosmological constant problem, explaining why the observed vacuum energy is non-zero, contrasting with traditional volume weighting approaches.

Contribution

It introduces an alternative volume averaging measure that resolves the incoherent predictions of volume weighting regarding the cosmological constant.

Findings

Volume averaging predicts a non-zero cosmological constant.

Traditional volume weighting predicts a probability of 1 for zero cosmological constant.

The new measure offers a coherent explanation for observed vacuum energy.

Abstract

In this paper, we give a possible solution to the cosmological constant problem. It is shown hat the traditional approach, based on volume weighting of probabilities, leads to an incoherent onclusion: the probability that a randomly chosen observer measures $\Lambda=0$ is exactly equal to 1. Using an alternative, volume averaging measure, instead of volume weighting can explain why the osmological constant is non-zero.
