A Strange Ripple in Spacetime Could Be the First Fingerprint of Dark Matter The search for dark matter, which makes up an estimated 85% of the universe's mass, has been a long and arduous journey.
Scientists have inferred its presence from gravitational lensing and cosmic microwave background radiation, but direct observation remains elusive.
A recent study by MIT and European researchers offers a promising lead, suggesting that colliding black holes might hold the key to detecting dark matter's faint signature in spacetime.
