Does how black holes inside galaxies orbit around the central black hole tell us anything useful? Could be my noobness, but the idea of a bunch of black holes orbiting a central black hole just seems messy. ha. Have we got the jist of what would happen if a black hole ate another black hole? if another black hole grew larger than the central one in our galaxy? or can we explain most other black hole on black hole interactions??

Black hole on black hole. New type of fetish.
Gravitationally, black holes are no different than any other massive object such as a star. If the sun were replaced with a black hole of similar mass, Earth happily continue orbiting without knowing the difference.

You could replace each star in the galaxy one by one with a black hole of the same mass and they would continue to orbit as before.
