  A brief discussion on the pseudo-complex General Relativity is presented. It
is shown that this theory is a viable extension of GR, with deviations centered
near to the event horizon. The theory introduces a dark energy accumulation,
due to the coupling to the central mass. Predictions of this theory are
resumed, as for example the structure in an accretion disk, with a dark ring
followed by a bright ring further in. The current Event Horizon Telescope
observation of M87 is not able to discriminate between GR and pcGR, due to a
low resolution. Further predictions are also discussed, as the physics of
neutron stars, the redshift at the surface of the star and Quasi Periodic
Object.
