Physicists have floated numerous theories to explain what dark matter might be, but to date, no experiment has turned up compelling evidence to support any of them. An international team of physicists, including 91自拍ers from the UW, is now working on a new kind of dark matter detector with the goal of capturing the first direct observation of the puzzling material. Results from the detector鈥檚 prototype have already ruled out one of the leading theories of how dark matter originated.
