When one snooker ball hits another, both spring away from each other in an elastic manner. In the case of two photons a similar process -- the elastic collision -- has never been observed. Physicists have now shown, however, that such a process does not only occur, but even could soon be registered in heavy ion collisions at the LHC accelerator.
