Story summary
- Alberto Magaraggia and Nico Cappelluti from the University of Miami report evidence of primordial black holes using data from the Laser Interferometer Gravitational-Wave Observatory (LIGO).
- They detected a gravitational wave signal, S251112cm, indicating a sub-solar-mass collision.
- Primordial black holes (PBHs) may contribute to dark matter, but their small size makes detection difficult.
- Further observations are needed, with LIGO upgrades and the Interferometer Space Antenna (LISA) expected to improve detection.
