The Super-K group first reported that neutrinos oscillated in 1998.
Curious headline since the solar neutrino missing mass problem was solved a while back. They already knew neutrinos have mass. I am a bit puzzled by this "revelation".
I don't write the headlines. All I do is post the stuff, and then wait for you to explain it to us.
My understanding of MSW is that it relies on the passage of the neutrino through matter to cause (or enhance) the flavor change, whereas other theories predict flavor changing oscillations as the neutrino travels trough essentially empty space.
Have you any insight into whether or not MSW is supported by this result?
