  Quantum geometrodynamics with intrinsic time development is presented.
Paradigm shift from full space-time covariance to spatial diffeomorphism
invariance yields a non-vanishing Hamiltonian, a resolution of the `problem of
time', and gauge-invariant temporal ordering in an ever expanding universe.
Einstein's general relativity is a particular realization of a wider class of
theories; and the framework prompts natural extensions and improvements, with
the consequent dominance of Cotton-York potential at early times when the
universe was small.
