Say a god got mad and could and did turn off the nuclear fires in our sun. About how long till earth freezes? We read that it takes an incredibly long to for the average photon produced in near the center of the sun until the time it scatters for the last time and leaves the sun, does that mean the sun will take a while to cool down, that time lengthened somewhat by the slow gravitational collapse of a shut down sun? Say we look only at the volume of the sun where most energy is produced. Particles leave this volume (photons and anti neutrinos). The number of particles in this volume reduces, four protons and two electrons go to one helium nucleus. Does this change in particle number have thermodynamic consequences? We know that a large flux of neutrinos can blow a star apart that goes supernova? Does this flux of neutrinos tend to polarize the positively charged matter and the negativley matter? If so are large electric fields generated in a supernova? From this does it follow that the constant flux of neutrinos in our sun give rise to some very small but constant outward force to the matter in the sun? Thank you for your thoughts.
