Today I gave my talk at the KITP workshop on Quantum Gravity Foundations; UV to IR. It was on Nonlocality in the Effective Field Theory of Gravity, reviewing many of our past results but centered on the theme that low energy quantum effects are nonlocal. This is a change from classical GR where we have a spacetime manifold, a local equation governing it, geodesics and crisp events. The workshop here is quite interesting and the setting is great. Today is also the start of my long sabbatical.
