Phys. Rev. D 49, 930–940 (1994)Dispersion of Newton’s constant: A transfer matrix formulation of quantum gravityReceived 14 September 1993; published in the issue dated 15 January 1994 A transfer matrix formalism applicable to certain reparametrization-invariant theories, including quantum gravity, is proposed. In this formulation it is found that every stationary state in quantum gravity satisfies a Wheeler-DeWitt equation, but each with a different value of the Planck mass; the value MPlanck4 turns out to be proportional to the eigenvalue of the evolution operator. As a consequence, the fact that the Universe is nonstationary implies that it is not in an eigenstate of Newton’s constant. © 1994 The American Physical Society URL:
