Quantum creation of an inhomogeneous unflationary universe

TL;DR

This paper explores how quantum effects can lead to the creation of an inhomogeneous universe that becomes homogeneous and isotropic on large scales during inflation, highlighting the role of quantum fluctuations near singularities.

Contribution

It demonstrates that quantum fluctuations of spatial topologies grow during universe creation, resulting in a large-scale homogeneous and isotropic universe, a novel insight into quantum cosmology.

Findings

Quantum fluctuations increase near the singularity.

Universe acquires large-scale homogeneity and isotropy.

Quantum creation process influences universe topology.

Abstract

The process of quantum creation of a qusihomogeneous inflationary universe near a cosmological singularity is considered. It is shown that during the evolution quantum fluctuations of spatial topologies increase and the universe acquires homogeneous and isotropic character on arbitrary large distances.
