# A Bouncing Cosmology from VECROs

## TL;DR

This paper proposes that a gas of VECROs in a contracting universe can prevent a Big Crunch, leading to a nonsingular bouncing cosmology, similar to how VECROs prevent singularities in black holes.

## Contribution

It introduces a novel cosmological model where VECROs induce a bounce, avoiding singularities in contracting universes, extending their known role from black holes.

## Key findings

- VECROs can form in a contracting universe to halt collapse.
- VECROs prevent the formation of a Big Crunch singularity.
- The model suggests a nonsingular bouncing cosmology.

## Abstract

We argue that, in the same way that in a black hole space-time VECROs will form in order to cancel the gravitational effects of a collapsing mass shell and prevent the formation of a singularity, in a contracting universe a gas of VECROs will form to hold up the contraction, prevent a Big Crunch singularity, and lead to a nonsingular cosmological bounce.
