Scientists just built the ultimate underground lair—no joke, it’s a mile under the French Alps—to hunt for dark matter, the mysterious stuff making up most of the universe. Their new detector is so sensitive, it can spot signals from particles way lighter than anything we’ve looked for before (think: electron-sized). If dark matter’s out there, this gadget might finally catch it—or at least rule out some suspects. It’s like CSI: Universe, but way nerdier. #Science #DarkMatter #ScienceNews
