It is shown that in Quantum Gravity, and more general: in Grand Unified Theory incorporating General Relativity on a basic level, there arise necessarily absolute limitations on measurement which one cannot evade by any "quantum nondemolition measurements". This fact is demonstrated not to oppose th
Infrared regularization of Feynman amplitudes in perturbative quantum gravity is discussed. Two familiar strategies, momentum cutoff and massification, are critically reviewed. Both methods rely on cancellations (in cross sections) between infrared divergences in individual Feynman diagrams on the o
