First post. I am doing research for a script I am writing. Figured this was a good place to pose the question. Could a solar flare burn off our atmosphere and/or cause enough radiation, heat, and damage that life could not survive? Basically, I need a natural way for the earth to be destroyed without using asteroids, aliens, nukes, etc..... OR something that would destroy the earth within ten minutes after humanity learning of its existence. We have thought of anti-matter clouds, large planetoids messing with gravity, black holes, gravitational wells, and a bunch of other stuff. But, I still want to go with a solar flare. Anyone who helps will be in the credits... not that you really care about that! Thanks!
