Big Bounce Genesis and Possible Experimental Tests -- A Brief Review

TL;DR

This review explores how dark matter properties could serve as experimental evidence for a bounce universe scenario, proposing model-independent predictions testable by direct detection methods.

Contribution

It introduces a model-independent approach to study dark matter production in a bounce universe and suggests testable predictions for experimental verification.

Findings

Dark matter properties can indicate a bounce universe

Model-independent predictions for dark matter detection

Potential experimental tests for early universe models

Abstract

We review the recent status of big bounce genesis as a new possibility of using dark matter particle's mass and interaction cross section to test the existence of a bounce universe at the early stage of evolution in our currently observed universe. To study the dark matter production and evolution inside the bounce universe, called big bounce genesis for short, we propose a model independent approach. We shall present the motivation for proposing big bounce as well the model independent predictions which can be tested by dark matter direct searches. A positive finding shall have profound impact on our understanding of the early universe physics.
