"It has been proposed that the anomlay in solar neutrino production is due to an error in the basic physics of neutrino emission rather than any significant error in our understanding of solar energy production. The conventional view of the behaviour of light and matter in a gravitational field has been modified such that the speed of light is dependent on the prevailing gravitional field and on the frequency of the associated wave. In this case it has been shown that particles below a critical rest mass will be unable to escape from the core of the sun and will remain oscillating inside the sun according to condition."
