# How do we know
the neutrinos would have been detected?

# we had neutrino detectors even back in the 80s
and we detected a surge in neutrinos around when the light from the supernova hit us

apparently in the paper today they point out that the neutrinos from sn1987a were a lot less energetic than the ones produced at cern. i doubt they draw any firm conclusions but i've not actually read the paper myself yet. i'll do that a bit later. it doesn't look like i'll get much coherent work done today.

# Fair enough.
Presumably not all neutrinos break the light barrier (if indeed any do) otherwise somebody would have noticed before now.

It'll be fascinating to see if anything comes of this.
