Black hole may be 'particle accelerator'

U.S. and Australian scientists said they have discovered how a black hole in the center of the galaxy is emitting gamma rays with extraordinary energies. Scientists said they were startled when they discovered in 2004 that the center of the Milky Way galaxy is emitting gamma rays with energies in the tens of trillions of electronvolts. But now astrophysicists at The University of Arizona, the Los Alamos National Laboratory and Australia's University of Adelaide said the black hole might be working like a cosmic particle accelerator, revving up protons that smash at incredible speeds into lower energy protons, creating high-energy gamma rays.

That's because the speed of dark is at least one mile per second faster than the speed of light. When you turn on the light, you never see dark leaving the room.

Have you seen these alternate theories on the Speed of Dark here?.
