Dark matter is an invisible form of matter believed to make up about 85% of all matter in the universe. Scientists have never directly detected it, but its gravitational effects on galaxies provide strong evidence that it exists. The mystery has gained fresh attention after the LUX-ZEPLIN experiment in a former South Dakota gold mine recorded a rare particle interaction that could potentially be linked to a dark matter candidate called a WIMP. However, researchers say the single event is not enough to confirm a discovery.

The LUX-ZEPLIN experiment has detected a rare particle interaction that looks unusually difficult to explain as ordinary background noise and appeared where dark matter might be…

Scientists used Earth’s magnetic field and atmosphere as a planet-sized detector to search for some of the lightest proposed forms of dark matter. The approach dramatically…

The world’s biggest dark matter search saw a particle it cannot explain

Until now, evidence for dark matter has come from observing its apparent gravitational effects.
