Possible Dark Matter Detected at Milky Way’s Core Could Hint at New Force of Nature

There’s a surplus of gamma rays spewing forth from the center of our galaxy, and astrophysicists say they don’t know where it’s coming from. One thing is clear, though: it could not have been caused by anything we consider ordinary in our galaxy.

What it could be, according to Tracy Slatyer of MIT and her colleagues at Fermilab, Harvard, and MIT, is excess light from colliding dark matter particles. If true, this observation would be the first-ever indirect detection of dark matter in our universe.
