  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.
