Recent observations suggest that the models of synchronized co-evolution of supermassive black holes (SMBHs) and their host galaxies in the early Universe are partially incorrect - Trakhtenbrot et al. (10 July 2015). They found in the galaxy CID-947, which is placed in time distance about 12 Gyr (z = 3.328), a black hole with a mass of about 10 % of the total galactic mass. On the other hand, the SMBH in such a normal-size galaxy achieves up to about 0.2 to 0.5 % of the host galaxy mass in the present day i.e. their mass is about 20 to 50 times smaller (!). This observational fact is consistent with the cosmology described within the Scale-Symmetric Theory (SST). Here we present a revised scenario for the evolution of galaxies. We can see all galaxies but we cannot see the initial period 7.75 Gyr of their 21.61 Gyr evolution (the Ludwig et al. data (2009) suggest that the Universe is about 22 Gyr old but within the Scale-Symmetric Theory we showed that we can see only the last period about 13.8 Gyr). During the unseen period, due to the inflows of dark matter and next of the turbulent inflows of dark energy, evolution of the initial protogalaxies had been differentiated. The SST shows that in the visible period of evolution of the Universe, the ratio of mass of the central black hole to total mass of galaxy (it concerns the quasars also) should be equal to or lower than 0.583 and this result is consistent with new data.
