Telescopes caught a photon from a gamma-ray burst that arrived late and wasn't absorbed — casting doubt on the constancy of the speed of light.

The most powerful gamma-ray burst in history produced a photon with hundreds of TeV energy. It reached Earth, though by ordinary laws it should have gotten stuck along the way. Perhaps the speed of light itself is not constant — such a shift in physics will open the door to new technologies.

🎯 The gamma-ray burst was nicknamed BOAT (Brightest Of All Time, meaning 'boat'), but the captured photon is just a drop in the bucket of its total energy.

🎬 The idea of a changing speed of light has been explored by science fiction writers, for example in the novel 'Spin' by Robert Charles Wilson.
