Consider Neutrinos: SN1987A and OPERA
Yesterday, after rumors surfaced on the Science Insider blog that OPERA’s startling superluminal result had been traced to a faulty cable, the collaboration sent out a press release stating that they had uncovered two previously unaccounted-for errors. Astronomers in particular have been skeptical of OPERA’s results based on an event that, coincidentally, occurred exactly 25 years ago today: the arrival of the neutrino pulse from Supernova 1987A. SN1987A is the closest supernova ever observed in modern times and still the only one for which we have detected the associated neutrino pulse, and it bloomed this night 25 years ago in the Large Magellanic Cloud.
