A very small dispersion in the speed of light may be observable in Fermi time- and energy-tagged data on variable sources, such as gamma-ray bursts (GRB) and active galactic nuclei (AGN). We describe a method to compute the size of this effect by applying the Feynman sum-over-histories formalism for relativistic quantum electrodynamics to a discrete model of space-time called causal set theory.
