# Bouncing cosmology from warped extra dimensional scenario

## TL;DR

This paper investigates how warped extra dimensions in a two-brane model can induce non-singular bouncing cosmologies on our visible brane, potentially resolving the big-bang singularity.

## Contribution

It demonstrates that warped extra dimensions can produce non-singular bounces in brane cosmology, a novel mechanism for avoiding the big-bang singularity.

## Key findings

- Warped extra dimensions lead to non-singular bounces.
- Parametric regions for bouncing are identified.
- Bouncing cosmology removes the big-bang singularity.

## Abstract

From the perspective of four dimensional effective theory on a two brane warped geometry model, we examine the possibility of "bouncing phenomena"on our visible brane. Our results reveal that the presence of warped extra dimension lead to a non-singular bounce on the brane scale factor and hence can remove the "big-bang singularity". We also examine the possible parametric regions for which this bouncing is possible.
