Nonsingular cosmological models

TL;DR

This paper introduces nonsingular cosmological models that transition smoothly from a collapsing phase to an expanding universe without encountering singularities.

Contribution

It presents a class of cosmological models that avoid singularities by describing a smooth transition from collapse to expansion.

Findings

Models successfully avoid singularities

Transition occurs smoothly without divergences

Provides a framework for nonsingular cosmology

Abstract

A short introduction to cosmological models that go from an era of accelerated collapse to an expanding era without displaying a singularity is presented.
