Story summary
- A recent LIGO signal may indicate primordial black holes formed in the early universe, according to astrophysicists Nico Cappelluti and Alberto Magaraggia.
- These black holes would differ from stellar remnants, arising from extreme density after the Big Bang, and could explain dark matter.
- Nevertheless, the detection remains unconfirmed.
- Future detectors such as LISA and Cosmic Explorer could improve detection and cosmology.
