Within the lacking part of ultimate theory, i.e. the Scale-Symmetric Theory, we described the evolution of massive galaxies. Within the new cosmology, applying very simple mathematics, we can answer following questions. Why many of the oldest most massive galaxies reside in clusters? Is the gravitational redshift important for the E/S0 galaxies? What is contribution of the kinematical Doppler effect of Special Relativity to the total cosmological redshift? Is the acceleration of expansion of the Universe an illusion? Why the massive red evolved galaxies are already in place at high redshift? Why the red-sequence has a boundary at z = 0.44? When and how were produced the first-generation stars the E/S0 galaxies consist of? What was the origin of a rapid build-up of the red sequence and why it is quiescent i.e. why there do not appear numerous new stars i.e. what are the phenomena responsible for the powerful shut-down mechanism of new-star formation i.e. why E/S0 galaxies evolve in a purely passive way? Why evolution of the most massive E/S0 galaxies was quicker for lower redshift i.e. why number of massive red galaxies is greater for redshift smaller than 0.7? Why there is a significant population of massive blue galaxies at high redshift?
