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."

I always knew I was more powerful because of my astrological sign. Now I have proof!
Or proof that my life sucks... either way, it's something!

And about Gamma Rays...

What does the Gay Married Men Association have to do with this A*-hole? Oh, wait, never mind...
