Operator analogues for interval, scalar curvature, values of the Einstein tensor are proposed. Quantum measurements of these observables lead to a paradox: different procedures of measurements can supply non equivalent geometrical pictures of space-time. A concrete example of such situation is provided.7 pages, LaTeX2eGeneral Relativity and Quantum Cosmologytext
