Quantum Gravity and Relative Locality

Abstract:
Several indipendent arguments suggest that the notion of locality should be revised at the Planck scale. I review a recently proposed scenario for a modification of locality such that events which are established to be coincident by nearby observers may not appear to be coincident in the coordinatization of spacetime by distant observers. This fits within a path to quantum gravity which Max Born proposed in 1938, involving curvature of momentum space. And a valuable example of relative-locality framework can be built around a kappa-Poincare phase space.
