Steven observed...........Neutrinos are the byproducts for the fusion of hydrogen nuclei. Instead of acting as a neutrino shield, the Sun becomes a source of neutrinos.Why is it then Mercury is not pushed out of it's orbit? The answer is that neutrinos do not readily interact with matter. That is a scientific fact.

Without commenting on Mercury or the perceived problem with a shield via the manner considered I think that nuetrinos will react with matter..they do with dry cleaning fluid I believe
