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 expected. Scientists are not claiming a discovery yet, but additional data could show whether this single mysterious event is the first hint of a long-sought dark matter particle.

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…

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

An unknown material fills the universe.
