The really cool possibility is that we may be able to use this to detect a supernova's neutrinos before the light arrives. This happened once before in 1987 https://en.wikipedia.org/wiki/SN_1987A [wikipedia.org] but in that case the supernova was very close and the tech was poor enough that we didn't realize the supernova neutrinos had arrived before hand until days after. If we could have this happen again we could know to point conventional optical telescopes at a supernova before the light arrived and get to see the fir
So basically the explosion at the heart of a supernova produces light and neutrinos together. But the light itself is retarded while within the star, giving the neutrinos a several hour head start. "really cool" indeed [I see what you did there].
One thing to keep in mind is that once light escapes the star, both the light wavefront and the neutrino wavefront propagate at lightspeed. So the head start will be independent of the distance to the exploding supernova.
