This article has put my mind at ease about being blown up by a blast of gamma radiation from space. The chance of a blast in the Milky Way galaxy is almost zero. They only occur in weak, "metal-poor" galaxies. There was only a 0.15% chance of a burst happening to weak galaxies around ours, and don't worry, our galaxy is twice as metal-y as those ( Read more... )
