Solar neutrino problem

The solar neutrino problem concerned a major discrepancy between the number of neutrinos predicted by theoretical models of the solar interior and direct measurements of the number of neutrinos flowing through the Earth. The discrepancy was first observed in the mid-1960s and resolved around 2002.
