“We still don’t know what dark matter is,” said John Terning, professor of physics at UC Davis, one of two theoretical physicists at the University of California, Davis who have a new candidate for dark matter, and a possible way to detect it. They presented their work June 6 at the Planck 2019 conference in Granada, Spain. “The primary candidate for a long time was the WIMP, but it looks like that’s almost completely ruled out.”
