> but is this a human extinction event? Seems like there's no prognosis as to what consequences a GRB event may have on humans specifically in the paper quoted on Wikipedia: “The greatest danger is believed to come from Wolf–Rayet stars, regarded by astronomers as likely GRB candidates. … if WR 104, at a distance of 8,000 light-years were to hit Earth with a burst of 10 seconds duration, its gamma rays could deplete about 25 percent of the world's ozone layer. This would result in mass extinction, food chain depletion, and starvation.” I suppose this topic is hard to speculate on, as it requires substantial knowledge on a variety of disciplines.
