There are no solar neutrinos. Several major experiments have been conducted to find them, but they are not there.
Something tells me I'm rising to bait by saying this, but you're wrong. Solar neutrinos most certainly do exist. They were first measured in the 1960's.
There used to be a solar neutrino deficit problem: the experiments only measured one third of the number of neutrinos that were predicted by the Solar Standard Model. Last summer, the reason for this was discovered by researchers at the Sudbury Neutrino Observatory: neutrinos have mass, and they change "flavor" as they travel. There are three flavors of neutrino, but the former experiments only measured one type, electron neutrinos. This wasn't expected to be a problem, because the sun only produces electron neutrinos, but as since they change flavor in transit, that assumption was wrong. SNO measures all three types of neutrino (electron, muon, and tau). When you add them all up, you get exactly what was predicted by the Solar Standard Model.

Yes, I was baiting you. Sorry. Yes, I know you are a physicist. (I've seen your posts before.) And yes, I am refering to the solar neutrino problem. Your argument (actually Sudbury's) that the neutrino problem has been solved is so bogus. Are you really satisfied to say that "Well, since we can't detect enough solar neutrinos, they must be turning into an undectable kind of neutrino. Since we can't detect them they must be there. Problem solved." I'm surprised that as a physicist you would accept this circular reasoning. When you can prove that neutrinos can change "flavor", and when they figure out a way to detect muon and tau neutrinos, and actually detect them, then I'll believe the sun's heat is really nuclear, and that the sun could be 4.5 million years old.
P.S. Did they really detect one-third of the amount predicted? I have read it was around 1%, which may be cosmic rather than solar, and that's why they came up with the flavor change theory in the first place. My understanding of the theory is that essentially all of the neutrinos change to the undectable forms before they reach earth, and they eventually change back into electron neutrinos because they oscilate among the three different flavors. Earth "just happens" to fall in the nondetectable zone. I'm just asking because you're a physicist. Thanks.
This really irritates me. Now, when I get home with the wrong flavor of neutrino, I can no longer blame the store for selling me the wrong neutrinos. Sigh.
I have to brush up on my particle physics... There has been some important work done lately and I'm not keeping track of it. 'Course, it's difficult enough to keep track of work in my sub-field, let alone a totally unrelated but way cool field...
