I don't get it. Wouldn't it take years for a far supernova to be detected? How is it only hours?

- pvg 4y agoThere's a flash of neutrinos as the supernova core collapses and it precedes the light by a bit. One reason being the neutrinos don't really care there's a whole supernova in the way but EM radiation does. https://en.wikipedia.org/wiki/Supernova_neutrinos https://en.wikipedia.org/wiki/Supernova_neutrinos
- murphyslab 4y agoSupernovas emit lots of different kinds of particles and radiation. Neutrinos depart & arrive before any other radiation. The gap is on the order of hours. So neutrinos can function as an early warning system.
