Black holes older than the Big Bang could explain dark matter
Some black holes roaming the Universe today may actually be older than the Big Bang. A new cosmic “bounce” model suggests the Universe expanded from an earlier contracting phase, allowing ancient black holes to survive the transition as cosmic fossils. These relics could potentially explain dark matter and why surprisingly massive objects appeared so early in cosmic history.
Research from the University of Portsmouth suggests black holes that formed before the Big Bang may still exist today as cosmic fossils. These ancient objects could help explain dark matter, the mysterious substance shaping galaxies. The study explores the idea that the Universe did not begin with a single Big Bang but rather a cosmic bounce, where an earlier universe contracted and then reversed to expand.
If correct, these primordial black holes could provide clues to dark matter's nature and the formation of the earliest galaxies.
