Early galaxies may contribute to the ‘afterglow’ of the universe

The “afterglow” of the universe is an important piece of evidence for the Big Bang. This background radiation also provides important answers to the question of how the first galaxies were able to form. Researchers at the Universities of Bonn, Prague and Nanjing calculate that the strength of this radiation has probably been overestimated up to now. If the results prove to be accurate, it would call into question the theoretical foundation of the standard model of cosmology.
