Record-Setting Dark Matter Detector Comes Up Empty -- and That's Good News
An anonymous reader quotes a report from Gizmodo: WIMPs (weakly interacting massive particles) are one of the most serious contenders for dark matter -- the "missing" mass supposedly constituting 85% of our universe. Given its elusiveness, dark matter tests the patience and creativity of physicists....
An anonymous reader quotes a report from Gizmodo: WIMPs (weakly interacting massive particles) are one of the most serious contenders for dark matter -- the "missing" mass supposedly constituting 85% of our universe. In a recent Physical Review Letters paper, scientists analyzed 280 days' worth of data from LUX-ZEPLIN, reporting the tightest ever upper limit on the interaction strength of WIMPs. The chemical element's high atomic mass and density make it potentially easier for scientists to detect any unknown particles that may pass through the detector.
