I saw a movie recently which I won't name because I don't want to ruin it for people who haven't seen it, but in short the grand finale sees Planet Earth destroyed by a massive solar flare.
The Solar flare (Wikipedia) entry says that they can release as much as 6 × 10/25 joules of energy. Obviously it doesn't go in to the possibility of anything greater than that wiping out earth, but is it completely impossible that this could happen, or is there an outside chance? The Mayans predicted the end of the world occurring in 2012, maybe this is what will cause it?
