It sounds like the title of a new James Bond movie, but Darkside 50 is actually one of 25 experiment-based searches around the world for dark matter. We believe that dark matter makes up one-fourth of the energy in the universe but, so far, have been unable to prove its existence. This particular experiment is based on the theory that dark matter is made of WIMPS (weakly interacting massive particles) (story, video): http://www.globalpost.com/dispatch/news/science/130524/on-location-video-mystery-universe-dark-matter
