Purely virtual extension of quantum field theory for gauge invariant fields: quantum gravity
Abstract Quantum gravity is extended to include purely virtual “cloud sectors”, which allow us to define a complete set of point-dependent observables, including a gauge invariant metric and gauge invariant matter fields, and calculate their off-shell correlation functions perturbatively. The ordina...
