Our Galaxy's Center is Full of Black Holes

NASA's Chandra X-ray Observatory has discovered thousands of black holes surrounding the supermassive black hole at the center of our galaxy (Sagittarius A*).

According to NASA:

Theoretical studies of the dynamics of stars in galaxies have indicated that a large population of stellar mass black holes — as many as 20,000 — could drift inward over the eons and collect around Sgr A*. This recent analysis using Chandra data is the first observational evidence for such a black hole bounty.
