but doesn't it correlate to any possible event yet, or are we just guessing about were it came from?

If it's a supernova event, hopefully we'll spot it in the next day or two.

I can't tell if this is a misinformed comment or an FTL neutrino joke.

Actually, neutrinos do arrive slightly faster than light from supernovae. Space isn't completely empty --- tiny amounts of interstellar gas give it a refractive index slightly higher than "perfect" vacuum, which ever-so-slightly slows down light. Neutrinos interact far less than light with matter; so, a supernova neutrino going at very nearly the speed of light can outrun a photon through space. In Supernova 1987A [wikipedia.org], neutrino detectors saw neutrinos about three hours before light reached earth's telescopes.
