A new study suggests the universe may have undergone a contraction phase before the Big Bang, proposing a "bouncing" cosmology model. Researchers hypothesize that dark matter could consist of primordial black holes formed during this contraction. Approximately 80% of the universe's matter is dark matter, which remains unidentified. Future gravitational wave observatories may detect waves from black hole formations, potentially confirming this theory.
