Some of the biggest black holes ever picked up through gravitational waves may not have formed in a single stellar collapse ...

The biggest black holes in the Universe may be built through chains of violent mergers deep inside crowded star clusters.

According to the study, this creates a forbidden mass range for stellar-mass black holes formed from collapsing stars.

About 28,000 light-years away, the globular cluster M80 is home to hundreds of thousands of stars bound together by gravity. Crowded environments like this can help drive the growth of black holes ...
