The MSW effect [1] causes the electron neutrino to have a different 
effective mass.  It's quite a strong effect (at least in the plasma of the 
sun).  Is it possible to have a MSW effect for neutrinos passing through 
the earth? The assumption being that neutrinos are more massive as 
they pass through the earth, thus explaining the high velocity being 
observed as compared to neutrinos propagating through the vacuum
or cosmic space.
