Bouncing cosmology inspired by regular black holes

TL;DR

This paper proposes a bouncing cosmological model inspired by regular black holes, featuring scale-dependent, nearly homogeneous universe that deviates from the cosmological principle at smaller scales.

Contribution

It introduces a novel bouncing cosmology model influenced by regular black holes with scale-dependent and anisotropic features.

Findings

Universe exhibits bounce behavior avoiding singularities

Model aligns with large-scale homogeneity observations

Deviates from perfect homogeneity at smaller scales

Abstract

In this article, we present a bouncing cosmology inspired by a family of regular black holes. This scale-dependent cosmology deviates from the cosmological principle by means of a scale factor which depends on the time and the radial coordinate as well. The model is isotropic but not perfectly homogeneous. That is, this cosmology describes a universe almost homogeneous only for large scales, such as our observable universe.
