Abstract
On our galactic centre an unusually strong radial magnetic field has been found near our Galactical Center. It is an important implication that the observed radiation from the GC cannot be emitted by the gas of the accretion disk due to accretion plasma fluid being hard to transfer across the magnetic field line by the Lorentz force. This is the first dilemma of the standard accretion disk model of black hole at the GC. The second dilemma is that the magnetic field with a lower limit of 8 mg near the GC is hardly produced by turbulence dynamo mechanism. Then author would like to talk about the strong radial magnetic field detected in the vicinity of the GC is consistent with the prediction from our model of supermassive object with magnetic monopoles. This is a strong evidence of both no black hole at the GC and existence of magnetic monopoles. Taking the RC effect (nucleons may decay catalyzed by MM) as an energy source, besides, we have proposed a unified model for many supernova explosion. In our model, the remnant of the distorted core of supernova is still a neutron star rather than a black hole no matter how huge of the supernova mass. That means black holes with stellar mass are impossible to be formed through supernova explosion. Query on the black hole models for other quasars and active galactic nuclei: The key dilemma of the black hole model is the question on the BH mass at the centre of AGNs.
