We show that QED in curved spacetime violates micro-causality, i.e. commutators of fields at spacelike separations do not vanish but exhibit a characteristic exponential fall-off over a length scale √ R/m, where R is a typical curvature and m is the electron mass. The violation of micro-causality is ultimately related to the generic focusing nature of… (More)
