If that's the case then the discrepancy may make sense since the neutrinos from the supernova should be I think higher energy.
Nope. As I said here the ones at CERN are 17GeV, whereas the ones from the supernova were 6.7MeV.
Ok. In that case this hypothesis seriously fails.

Perhaps the end of the era of the light cone and beginning of the era of the neutrino cone? I'd be curious to see your probability estimates for whether this theory pans out. Or other crackpot hypotheses to explain the results.
