The Pros and Cons of a Supernova Going Off

Bob Greene: If Beetle just goes though, won't it sort of flash out the night sky for us for a significant amount of time? He says they are predicting that it would be visible like the full moon, even during the day. The first thing to escape from a supernova is not the photons or anything else,. No, it's the neutrinos. They just go through it. So I'm going to be on the lookout for news that a pulse of neutrinos have been detected from the direction of Beto juice. But if that never happens, I have a backup plan. And maybe it'll happen. You never know.
