But maybe the details of the rate, ratios of the rates of the high energy and low energy neutrinos are somehow wrong. people, this, this is a great incentive for people like Bacall to refine the solar model to exquisitely high precision. maybe our understanding of the processes in the detector are wrong. in fact it turns out in that, that, that the answers given in 2001, by measurements using the Sudbury Neutrino Observatory this is a completely different technology.
