It is shown that the temperature of the MW background radiation might be directly connected with the details of the quark-hadron phase transition. In fact, at temperatures just above 10 GeV the universe has no room to contain the present baryon number in hadron form. This temperature might be smaller, even by a large factor, if a part of the present entropy originated at a redshift of from 10 to 100.

Abstract
It is shown that the temperature of the MW background radiation might be directly connected with the details of the quark-hadron phase transition. In fact, at temperatures just above 10 GeV the universe has no room to contain the present baryon number in hadron form. This temperature might be smaller, even by a large factor, if a part of the present entropy originated at a redshift of from 10 to 100.
