This result suggests neutrino travels about 1 in 50000 parts faster than light. This effect would have a huge impact on the detection timing in cases of neutrinos that had light years to travel, would it not? We know at the moment of core collapse a type II supernova gives off a massive burst of neutrinos. We also know that while the neutrinos would exit the supernova almost unimpeded, the electromagnetic manifestation of the supernova takes time it work it's way out of the star and make the supernova visible through electromagnetic observation, right?. This means the neutrino flux from supernova will always arrive on earth sooner than any visible sign that the star has gone supernova, right?
But if neutrino travel faster than light, that would mean further the supernova, the greater the observed lag time between when neutrinos are observed in the salt mines, and when the light is seen in telescopes, right? Do we observe this??
With a speed advantage of 1 part in 50000, a neutrino burst from a supernova in the magellonic cloud 150,000 light years away should gain 3 years on associated light burst, right, and arrive at least 3 years earlier than visible signs, right? Yet neutrino burst from the 1987A1 supernova in the large megellanic cloud was detected just 3 hours before the light burst, the 3 hours being consistent with how long the energy of the core collapse would take to work it's way out through the layers of the star out to it's surface.
So any thoughts? Where was the additional neutrino speed then when supernova 1987A1 exploded?
