Dark matter could be masquerading as a black hole at the Milky Ways core

Astronomers propose that an ultra-dense clump of exotic dark matter could be masquerading as the powerful object thought to anchor our galaxy, explaining both the blistering speeds of stars near the center and the slower, graceful rotation of material far beyond. This dark matter structure would have a compact core that pulls on nearby stars like a black hole, surrounded by a broad halo shaping the galaxys outer motion.
