|
|
Longstanding theories suggest that there should be abundant small black holes—perhaps as many as 20,000—within a few light years of Sagittarius A*. This is both because small black holes likely gravitate toward their supermassive counterparts, but also due to the rich environment of dust and gas surrounding galactic cores, which provides fertile ground for the formation of huge, short-lived stars that collapse into black holes after they explode as supernovas.
