Evidence of Dark Matter Found?

  Gamma-ray photons seen emanating from the center of the Milky Way galaxy are consistent with the intriguing possibility that dark-matter particles are annihilating each other in space, according to research submitted by UC Irvine astrophysicists to the American Physical Society journal Physical Review D. 360-degree panorama view of the Milky Way Galaxy (an assembled [continue reading]
