Reply to comment by Andromeda321 in Gaia discovers a new family of black holes: astronomers studied the orbits of stars and noticed that some of them wobbled on the sky, as if they were gravitationally influenced by massive objects. No light could be found using several telescopes, leaving only one possibility: black holes. by Andromeda321

> This is super exciting because it now implies that these black holes in orbits are actually rather common in space- more common than ones where the black hole and star are closer at this rate!- and the trouble is detecting them.

If it turns out that galaxies contain far more black holes than previously assumed, what ramifications might that have, e.g. for understanding galaxies' masses, rotations, dark matter complements, etc.?
