(a) The phenomenological model of AGN with the central stationary black hole. The meaningless singularity occurs at the center inside the black hole. (b) The microscopic model of AGN with the central stable SPC. In due course, the neutrinos of huge energies may escape through the vista to outside world. Accepted notations: EH = event horizon, AD = accretion disk, SPC = superdense protomatter core, PC = protomatter core.
