Early next spring researchers will begin installing two experiments there—both of them at the leading edge of 21st-century physics. The Large Underground Xenon experiment, which already is taking test run data in a building on the surface, aims to become the world’s most sensitive detector to look for a mysterious substance called dark matter. Thought to comprise 80 percent of all the matter in the universe, dark matter remains undetected so far. The second experiment, the Majorana Demonstrator, will search for one of the rarest forms of radioactive decays—neutrinoless double-beta decay. Majorana could help determine whether subatomic particles called neutrinos can act as their own anti-particles, a discovery that could help physicists better explain how the universe evolved.No mention of LBNE, the long-baseline neutrino experiment that was in limbo and some funding trouble.
