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

Understand

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.
