This is not how orbits work in galaxies. Every star is attracted to every other star in the galaxy. (Plus the dark matter halo, which we will ignore for now.) A SMBH can put 10,000,000 solar masses into the volume of our solar system, which is a much larger average density than the rest of...

This isn't all that uncommon in observational astronomy. Its really tough to get an idea of what is going on.

And that is why people say "almost every." They seem to be present in a large fraction of major galaxies.

As far as I understand, Relativity, as a classical theory, is known to be woefully incomplete on the scale of the singularity. Quantum mechanics will have something to say about confining huge amounts of mass to small volumes and yet it does not inform the model of the classical singularity. So...
