Fluffy ball of darkinos could be lurking at the center of the Milky Way

9 min read

In the summer of 2014, astronomers watched with giddy anticipation as a cloud of gas, known as G2, swung dangerously close to a supermassive black hole at the center of the Milky Way. Sparks didn’t fly, nor did a feeding frenzy ensue. Instead, G2 zipped by unscathed, surviving what astronomers thought would be a near-death experience. 

But black holes are big bullies, so the fact that the gravity well ignored the gassy passerby was more than surprising. It seemed impossible. Now, astronomers are saying that the supermassive black hole in the center of our galaxy is not a black hole at all, but rather a fluffy ball of dark matter. New research suggests this strange hypothesis is able to account for the “impossible” encounter as well as all observations of the galactic center — and then some.
