Creation of Ring Galaxy and the general movement of Stars

 Galaxies 'die' from the centre, creating an empty space that gets bigger and bigger, suggesting the general movement of matter is away from the Core forming Ring Galaxies. Dying from the middle indicates stars are spiralling from the central object, thought to be a Super Massive Black Hole, as matter close to this thing is generally moving away. For galaxies to remain active requires stars to be replaced at the centre were matter arrives around this central object forming concentrations of stars called the Torus - making it the fulcrum of galaxy evolution. When this system fails the stars moving away are not replaced and a hole appears which gets bigger. Thus, the movement of stars across the Galactic Plane is an outward spiral.
This process is impossible to associate to a Black Hole as the Core. It’s physical properties and connection to outward drift of matter may be better associated to a different object.
