Creation of Ring Galaxy and the general movement of Stars

Galaxies seem to fail from the centre, creating an empty space that may get 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 their formation close to the central object, thought to be a Super Massive Black Hole, as matter close to this thing is generally moving away. For this process to continue 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.
If this system fails the stars moving away are not replaced and a circular space appears which gets bigger. Thus, the general movement of stars across the Galactic Plane is an outward spiral and the entire galaxy is made by growth.

This process associates to Relativity as a Black Hole is the Core. It’s physical properties and the connection to the mass of the Galaxy as a causal link are exclusively explained in growth.
