Here we show that the mainstream cosmology incorrectly describes evolution of the early Universe. Using the NASA/ESA Hubble Space Telescope, astronomers discovered galaxy GN-z11 that is placed close to the more distant edge of the region of reionization i.e. is placed in time distance about 13.4 Gyr. It is assumed that the reionization had begun due to the grouping of the first stars in quasars. On the other hand, we know that transformation of quasars into galaxies lasts a few gigayears (Gyr). It leads to conclusion that the mainstream-cosmology description of the early Universe is incorrect because in the field composed of the “free” first stars cannot appear galaxies during about 200 million years. The Scale-Symmetric Theory (SST) provides the correct description of evolution of the early Universe and the observed most distant Universe (they are not the same thing) and shows that the period called dark ages is an illusion. SST shows that in the most distant observed Universe there should dominate galaxies, not quasars and/or free first stars.
