So why are the speeds seen by OPERA not achievable by the SN 1987A neutrinos?
I don’t know...
Neutrinos come in multiple mass eigenstates. Strictly speaking, all we know is that _some_ SN 1987A neutrinos arrived within hours of the flash of light. The Lorentz-violating eigenstate could have arrived during the Middle Ages, for all we know. Or arrived two years in advance, but dispersed over the period of 6 months and undetectable above background noise. There is a theory that it arrived 5 hours earlier, but it was only seen by one detector and discounted as a statistical fluke.
Wait why did the neutrinos of that supernova arrive 3 hours earlier if we're going to assume this experiment is wrong and c is still the ultimate speed limit? How can neutrinos beat light if they have mass?
The light from the supernova only appears a few hours after the explosion, because it is initially blocked by cool shock front that is ejected during collapse.
