Not very far, as it turns out, but the answer is incomplete without showing in a calculation that gamma rays won't even reach the ocean surface if the detonation is as deep as posted in the question. Once leaving the ocean, gamma rays can be detected very, very far away … Web30 jun. 2011 · This new observation is much more stringent, however, because GRB 041219A was at a distance estimated to be at least 300 million light years. In principle, the tiny twisting effect due to the quantum grains should have accumulated over the very large distance into a detectable signal.
