Description
Although perturbatively non-renormalizable, general relativity is a perfectly valid quantum theory at low energies. Treated as an effective field theory one is able to make genuine quantum predictions by applying the conventional rules of quantum field theory. The low energy degrees of freedom and couplings of quantum gravity are fully dictated by the symmetries of general relativity. At long distances, the leading quantum corrections are precisely induced by the low-energy fluctuations of the massless graviton. Non-local effective actions efficiently encode the latter class of quantum corrections. In this talk I will provide an overview of recent progress in infrared quantum gravity.
