Gamma-ray Burst Photon Delay as Expected by Quantum Gravity

In this illustration, one photon (purple) carries a million times the energy of another (yellow). Some theorists predict travel delays for higher-energy photons, which interact more strongly with the proposed frothy nature of space-time. Yet Fermi data on two photons from a gamma-ray burst fail to show this effect, eliminating some approaches to a new theory of gravity.

Animation showing how the photons may have acted if the structure of space-time was foamy.  However, Fermi data has shown that that effect does not exist.    Animation showing how the photons may have acted if the structure of space-time was foamy.
