Query: Experimentally testing asymptotically safe quantum gravity with
  photon-photon scattering   Matter-quantum gravity interactions can be used for direct and also indirect
experimental tests of quantum gravity. We focus on photon-photon scattering in
asymptotically safe gravity as a direct test of the small-scale structure of
spacetime, and discuss how near-future experiments can probe asymptotic safety
in a setting with large extra dimensions.
