Critique of proposed limit to space--time measurement, based on Wigner's clocks and mirrors

Abstract

Based on a relation between inertial time intervals and the Riemannian curvature, we show that space--time uncertainty derived by Ng and van Dam implies absurd uncertainties of the Riemannian curvature.
