Dark Matter May Be Made of Black Holes From Another Universe

"The cosmic bounce model suggests that the universe expands, contracts, and expands again in an endless cycle, with each universe arising from the ashes of the previous one."

"Structures larger than about 90 meters could survive the final collapse of a universe and endure into the next, potentially seeding the formation of giant structures in the early universe."

"The dominant explanation for dark matter has been that it is an unknown particle, but physicists are now exploring the possibility that it may be an abundant population of small black holes."

A recent cosmological model combines cyclic universes and primordial black holes to explain dark matter. This model proposes that the universe undergoes endless cycles of expansion and contraction. Structures larger than 90 meters could survive the universe's collapse and seed new formations. This challenges the traditional view of dark matter as unknown particles, suggesting instead that it may consist of small black holes. Despite its appeal, this idea faces significant challenges in proving the existence of these primordial black holes.
