Phys. Rev. D 54, 1500–1513 (1996)Strong coupling quantum gravity and physics beyond the Planck scaleReceived 11 January 1996; published in the issue dated 15 July 1996 We propose a renormalization prescription for the Wheeler-DeWitt equation of (3+1)-dimensional Einstein gravity and also propose a strong coupling expansion as an approximation scheme to probe quantum geometry at length scales much smaller than the Planck length. We solve the Wheeler-DeWitt equation to the second order in the expansion in a class of local solutions and discuss problems arising in our approach. © 1996 The American Physical Society URL:
