On Sagittarius A* - Theory and Observations

Massive and supermassive dust spheres (with a zero internal pressure) collapse to full globes of finite volumes, whose surfaces have the properties of the event horizon around a mass-point. This fact explains the observational data concerning Sagittarius A* (SgrA*). By virtue of Hilbert’s repulsive effect, both the event horizon of a mass-point and the event horizon of a full globe cannot swallow anything.
