A loop quantum multiverse?

TL;DR

This paper discusses recent advances in loop quantum cosmology that enable the analysis of highly inhomogeneous space-times, opening the possibility of exploring multiverse scenarios within this framework.

Contribution

It introduces effective methods that improve control over inhomogeneous space-times, facilitating qualitative studies of multiverse scenarios in loop quantum cosmology.

Findings

Enhanced control over inhomogeneous models

Qualitative analysis of multiverse scenarios possible

Advances in effective methods for loop quantum cosmology

Abstract

Inhomogeneous space-times in loop quantum cosmology have come under better control with recent advances in effective methods. Even highly inhomogeneous situations, for which multiverse scenarios provide extreme examples, can now be considered at least qualitatively.
