Right, I’m not sure which is deadlier, X, or over what distance... I think GRBs happen when a black hole is formed and as much energy as the Sun releases over its entire lifetime is released in just a few seconds, whereas the 3C321 jet comes from a supermassive black hole that’s feeding on stars, other black holes, and/or massive clouds of dust and gas. I know wouldn’t want to be spotlighted by jets from either one, that’s for sure, lol!
good answer... guess I’m going to have to go look it up...
ah...
