LIGO Detects Signal Suggesting Primordial Black Holes' Existence

4/12/2026

Summary

Story summary

LIGO detected a signal labeled S251112cm that may provide evidence for primordial black holes, which could account for dark matter.
The signal suggests a merger involving a black hole with less mass than the Sun, challenging conventional astrophysics.
Researchers from the University of Miami say these primordial black holes formed after the Big Bang.
Upgrades to LIGO and new detectors may enhance search, but more detections are needed for confirmation.
