: One of the nost fascinating things in astrophysics these days are gamma ray bursters (GRBs), which may or may not be related to neutron stars and possibly black holes. A GRB, if found to be within a distant galaxy, may constitute the single most energetic event short of the Big Bang itself. A recent theory (for some types, anyway) is that two neutron stars, recently formed of dual supernovae in a binary star situation, revolve around each other in a decadent orbit, faster and faster, closer and closer, until they whir around at blinding speed and come in contact, annihilating themselves and sending out a vast shower of gamma radiation in the process. Do these things result in a black hole or sheer destruction? It has been postulated that a GRB within a few thousand light years of earth may spell doom for earthlings due to sever gamma radiation...any thoughts, folks?
