That always astounded me: Neutrinos hardly interact at all, but as I understand supernovas it is the neutrinos that cause all the outer layers of the star to blow off at high speed. Supposedly some of the elements heavier than iron get formed by fusion during that explosion. That's a lot of energy transferred to a lot of mass just from neutrinos. So, that's a LOT of neutrinos.
The actual source of the neutrinos is what, something about making a neutron star out of the iron core of the star? Would that be too many neutrinos for just the iron core?
