Scientists May Have Found Dark Matter’s Fingerprint in a Black Hole Collision

MIT-led researchers built a method to model how black hole merger signals could change if the holes pass through dense dark matter.

They tested the approach on 28 clear LIGO-Virgo-KAGRA events and found one, GW190728, with a possible dark matter-related hint.

The team is not claiming a detection, but says the result shows gravitational waves could become a new way to probe dark matter.

The work was published in Physical Review Letters and could help study a substance seen only through its gravitational effects.
