Interesting article on solar flares, gamma ray bursts and where we are at in the cosmos. Interestingly enough, we are now shifting our placement in the milky way, one of the things the mayan calendar tends to confirm, which can cause..strong reactions. Long article with links to other articles. Its real interesting to see the old cave paintings and drawings from around the same time period the last time this happened.
