I find it weird that black holes would be moving throughout the galaxy because most are stationary.

A fluffy cluster of stars spilling across the sky may have a secret hidden in its heart: a swarm of over 100 stellar-mass black holes.

The star cluster in question is called Palomar 5. It’s a stellar stream that stretches out across 30,000 light-years, and is located around 80,000 light-years away.

Such globular clusters are often considered ‘fossils’ of the early Universe. They’re very dense and spherical, typically containing roughly 100,000 to 1 million very old stars; some, like NGC 6397, are nearly as old as the Universe itself.
