[QUOTE="James Snover, post: 16367184, member: 67454"] This wouldn't be a pulsar, as such. What happens is that supernovas shoot out polar jets, from the North and South poles of the stars, whose collimation somehow persists for thousands of light years. We don't really understand how they can stay so tightly collimated, or in a "beam," over such great distances. In addition to all the ordinary omnidirectionally-radiating energy and debris. The inverse square law protects us from all the omnidirectional blast effects. But the polar jets would be like getting blasted in the face by a Star Wars Deathstar-on-steroids. But, also, highly unlikely to happen because it would have to have been pointed where we are now, 700+ years ago. But, if it DID happen, I think we'd know it was about to happen because we would see, for a short period, Betelgeuse becoming insanely bright. Way brighter than the noon-day sun in the middle of desert. 100 to 1,000 times brighter than the sun; really we have no way to calculate it. You see that, say your goodbyes and say your prayers. But, the odds are two in 700-light years multiplied by two moving bodies (us and Big B). Pretty much zero. [/QUOTE]
