Ja. Debarros et N. Pintoneto, THE CAUSAL INTERPRETATION OF QUANTUM-MECHANICS AND THE SINGULARITY PROBLEM AND TIME ISSUE IN QUANTUM COSMOLOGY, International journal of modern physics D, 7(2), 1998, pp. 201-213
We apply the causal interpretation of quantum mechanics to homogeneous
quantum cosmology and show that the quantum theory is independent of
any time-gauge choice and there is no issue of time. We exemplify this
result by studying a particular minisuperspace model where the quantu
m potential driven by a prescribed quantum state prevents the formatio
n of the classical singularity, independently on the choice of the lap
se function. Hence, within the framework of the causal interpretation
of quantum cosmology, the fast-slow-time gauge conjecture is incorrect
for homogeneous minisuperspace models.
