Hello.
I wonder - is the CνB energy curve expected to follow the Boltzmann distribution?
In the 2 seconds neutrinos were in equilibrium with matter, did they bounce off enough to even out the energy?
I'm asking because a back-of-envelope computation gives cosmic neutrino speeds of ~0.09c, whereas neutrinos from solar events, geoneutrinos, supernovas etc. travel so close to c we can't distinguish them.
So is there a clear distinction, CνB radiation is slow, and modern neutrinos are fast?
