However, a team of astrophysicists have recently discovered black holes in these groups of stars, challenging what we now know about these clusters and where and how black holes develop.

These globular star clusters could have possibly up to tens of millions of stars that can collide with each other. Because of this, it was originally thought that any black holes that formed in a cluster would be ejected. Scientists believe that these stars are continuously playing bumper cars with each other and slinging black holes out of their area until they no longer exist. However, scientists recently discovered black holes in these clusters, disproving 40 years of theories.
