How far away do you have to be to avoid getting gamma'd?
- cthalupa 8y agoDepends primarily on how far away it is. Scientists are pretty sure they're only 2-3 degrees wide at the source, so the closer you are, the less distance you would need to travel. Of course, the farther you are, the less energetic it is. So, if GRB are 2 degrees wide at the source, and it occurs 8000LY away, and is pointed directly at us, we'd need to travel 136LY away. The solar system is moving at 1/1300 the speed of light. I'm not sure how Apep is moving relative to us, but assuming it's stationary, we'd need ~175k years to move out of the crosshairs by sitting here on the planet.
