Video: Dark Matter Hunt with LUX-ZEPLIN
Researchers at the Department of Energy’s SLAC National Accelerator Laboratory are on a quest to solve one of physics’ biggest mysteries: What exactly is dark matter – the invisible substance that accounts for 85 percent of all the matter in the universe but can’t be seen even with our most advanced scientific instruments?
Symmetry: A New Search for Dark Matter 6,800 Feet Underground
Prototype tests of the future SuperCDMS SNOLAB experiment are in full swing.
Standard Model of the Universe Withstands Most Precise Test by Dark Energy Survey
SLAC and Stanford astrophysicists made crucial contributions to the galaxy survey, showing that the universe clumps and expands as predicted by our best cosmological models.
Construction of Massive Neutrino Experiment Kicks Off a Mile Underground
A unique groundbreaking ceremony marked the start of construction of the Long-Baseline Neutrino Facility – future home of the Deep Underground Neutrino Experiment, which promises to shed new light on how the universe works and why matter exists.
