After a Century of Searching, We May Have Finally Seen Dark Matter

Using gamma ray data from NASA's Fermi Space Telescope, a Japanese physicist has identified a halo of extremely energetic photons around the Milky Way's center that matches predictions for annihilating dark matter particles. If confirmed, humani...
