“…If quantum fluctuations of the background are taken into account, quantum gravity leaves no "external" time parameter to describe the evolution of matter configurations in this background. Indeed, the solutions of the Wheeler-De Witt equation [3] H|Ψ = 0 (1) where H is the Hamiltonian density of the interacting gravity-matter system can contain no reference to such time when there are no contribution to the energy from surface terms at spatial infinity. This is due to the vanishing of the time displacement generator and even though the theory can be unambiguously formulated only at the semi-classical level, such a consequence of reparametrization invariance should have a more general range of validity.…”

“…Damals war die Quantenfeldtheorie noch wenig entwikkelt, jedoch war die Umwandlung eines Lichtquants bei Energieerhaltung in ein Elektron-Positron-Paareine Voraussage der Diracschen Theorieexperimentell bereits bestatigt worden. Untersuchungen aufgrund der Quantenfeldtheorie von B. de Witt [23], von R . Sex1 und H. Urbantke I241 sowie von Ya.…”
