People here often state that black holes aren't real.
What are the massive, dark and compact objects at the core of galaxies then?
I've heard people say that pic rel is just stars orbiting something akin to the eye of a hurricane, that there is no mass there.
I could be wrong but the orbits seem too extreme for it to be an eye, such a thing would be larger given the size of the galaxy.

What is the star going around bros?
