To help anyone silly enough to listen, understand what I'm going on about, Imagine two stars orbiting each other. A binary i think you call it. If a third star was orbiting the two, would it orbit the biggest star or would it orbit the center of mass of the two stars. And how would this work if we added a million stars.
If this sounds like rubbish to you please tell me why and have a good laugh at my limited understanding.

Black holes have signatures that a centre of mass doesn't.
For example one doesn't get accretion matter forming around a centre of mass.
Particles of accretion matter falling into a black hole can collide prior to passing through the event horizon and are a source of X-ray radiation.
While this phenomena can also occur with other massive objects such as neutron stars and white dwarfs, since accretion matter is colliding onto a
surface, the surface warms up and emits infra-red radiation.
Black holes by their nature are defined by an event horizon and not a surface and as such cannot emit infra-red radiation. Any form of radiation (except Hawking radiation) cannot pass through the event horizon back into space.
