(0.0K) | GRB
971214 is 12 billion light years away, that means that light,
and all electromagnetic radiation, takes 12 billion years to
travel that distance. Because gamma rays are a form of electromagnetic
radiation, it would also take gamma-rays 12 billion years to
traverse the distance between GRB 971214 and Earth. Consequently,
GRB 971214 exploded 12 billion years ago. |
