GoKawiilLUX-ZEPLIN Detector Records Unexplained Xenon Nucleus Recoil, Possible Dark Matter Signal
Physicists at the Sanford Underground Research Facility in South Dakota detected an anomalous energy signature inside a liquid xenon tank, caused by something striking a xenon nucleus and making it recoil. Researchers cannot yet identify the source of the collision, but they say it could represent the strongest physical evidence yet for dark matter, potentially a Weakly Interacting Massive Particle (WIMP) passing through Earth.
