Physicists Go Way Underground to Hunt for Dark Matter http://ifttt.com/images/no_image_card.png

Dark matter makes up about 90 percent of the universe's mass—but it's invisible. How do you detect the invisible? First you have to figure out what you're looking for. One theory says that dark matter exists alongside normal matter in the form of weakly interacting massive particles (WIMPs). So researchers built this thing, the DarkSide-50. It's one of the most sensitive dark matter detectors on the planet, and it will be switched on early next year at Gran Sasso National Laboratory, a sprawling subterranean playground for particle physicists northwest of Rome.
