The Signal in the Dark: What the LUX-ZEPLIN Detector's Mysterious Finding Could Mean for Physics
A single unexplained particle interaction deep underground has physicists buzzing. The LUX-ZEPLIN experiment's tantalizing blip doesn't prove dark matter exists — but it's the closest anyone has come, and the implications are enormous.

The Signal
Deep inside a former gold mine in South Dakota, nearly a mile beneath the Black Hills, something strange just happened. The LUX-ZEPLIN detector — a towering cylinder of ultra-pure liquid xenon buried in the Sanford Underground Research Facility — recorded a single particle interaction that doesn't match anything in the known physics playbook. After months of analysis, the team behind the experiment says this lone, ghostly blip could be the first direct evidence of dark matter: the...
