A Strange Ripple in Spacetime Could Be the First Fingerprint of Dark Matter
Researchers tested 28 black hole mergers and found one event, GW190728, that may show a dark matter imprint, though not a confirmed detection.

So far, dark matter is only hypothetical, but a research team wants to have developed a method to track it down.
Scientists May Have Found Dark Matter’s Fingerprint in a Black Hole Collision
Scientists have developed a new technique that could turn black hole collisions into cosmic detectors for dark matter, revealing faint traces hidden inside gravitational waves. Dark matter is believed to account for most of the matter in the universe, yet it appears to interact with ordinary matter only through gravity. Scientists think that if two [...]
Signals have been detected in gravitational waves that, according to a new study, could indicate the influence of dark matter during the merger of black holes.
A strange ripple in spacetime could be the first fingerprint of dark matter
Black holes crashing together may be revealing clues about dark matter hidden across the universe. Physicists created a new model predicting how dark matter could subtly distort gravitational waves produced during black hole mergers. When they tested the method on real LIGO data, one signal stood out as potentially carrying a dark matter imprint.
Dark matter may have left its signature in deep space seven years ago. And scientists may have only noticed it now. It is the fascinating hypothesis (still to be verified) advanced by an international team of researchers who analyzed the gravitational waves generated by the collision of two black holes. What is and how dark matter works Dark matter is one of the greatest mysteries of modern physics. It does not emit light, cannot be observed dir…
A study published in Physical Review Letters indicates that the undulations produced during certain cosmic fusions may reveal the presence of black matter around the colliding objects.

The researchers remain cautious. They …
