Milky Way's Black Hole a Gamma Source?
eldavojohn writes "A paper recently accepted for publication (preprint here) proposes a sound explanation for the source of the gamma rays that permeate our galaxy. The Milky Way's central object Sagittarius A*, widely believed to be a supermassive black hole, is now suspected to be the source. To test this theory, two scientists created a computer model to track the protons, flung outward with energies up to 100 TeV by the intense magnetic fields near the event horizon, as they make a random walk through the plasma environment. It can take thousands of years for them to travel 10 light-years from the black hole, where they collide with lower-energy protons to form pions. These decay into gamma radiation emanating from a torus-shaped region around the central object."

Would that make it an "A-Hole" ?????
Agent K: A *person* is smart. People are dumb, stupid, panicky animals, and you know it.

Well now I'm thinking of heating up a frozen BBQ sandwich. Thanks.
