How normal is the sun?

  1. Oct 15, 2007 #1
    I read a article describing the normality of the sun. It actually described that the sun is pouring the solar neutrino in less amount then predicted by the theory of particle physics. It is due because the sun is right now "boiled off" i.e. its rate of nuclear burning is decreased. If so then the energy due to the sun must have decreased. Is this sort of process possible? How?

    The solar (electron) neutrino shortful was understood once physicists discovered that neutrinos (which come in three forms) can and do change form, while travelling from the sun to the earth. When experiments were devised to measure all neutrino forms from the sun, the shortfall was no longer there,
