I asked Super what sterile neutrino's had to do with big bang and origin of life on Earth, he replied thus:

But this has not been shown in any conclusive way. The fertile neutrino, now, that's another story. Never been detected, but it could nicely explain the origin of life on earth and the universe. They would be able to penetrate deep into anything they encountered and thus spawn life almost anywhere.
Those are my ideas. ”
My reply:
you are winding me up, never mind
I just found this:
http://www.sciencedaily.com/release...30128075950.htm
"Neutrinos are invisible, uncharged, nearly massless particles that, unlike other kinds of radiation, speed through the universe unhindered by planets, stars, magnetic fields or entire galaxies.
The particles are emitted by phenomena scientists believe can help them understand the origins of the universe. "
and this for your reference re 'sterile' neutrino's
"The possibility of sterile neutrinos — neutrinos which do not participate in the weak interaction but which could be created through flavor oscillation (see below) — is unaffected by these Z-boson-based measurements, and the existence of such particles is in fact supported by experimental data from LSND. The correspondence between the six - currently known - quarks in the Standard Model and the six leptons, among them the three neutrinos, provides additional evidence that there should be exactly three types. However, conclusive proof that there are only three kinds of neutrinos remains an elusive goal of particle physics."
They are a 'missing ingredient' of that I am sure.
