that the burst was 1 in a 10,000-year burst, and it’s unlikely we’ll ever see another like it in our time.
Instead of experiencing fast jumps in energy as it evolved, the bright gamma-ray burst we detected showed a very smooth evolution, with the jet of energy evolving relatively over time. It’s a massive change from what we expect from these kinds of events, and it has left scientists digging for answers.
