Summary

Story summary

The LIGO-Virgo collaboration observed gravitational waves from event S251112cm, where one object had a mass too small for known black holes or neutron stars.
The observation could indicate the existence of primordial black holes and their possible role in dark matter.
Researchers caution that the signal could be a false alarm because the likelihood of such detections is low.
Confirmation of primordial black holes remains uncertain without further similar events.
