Summary

The quantum effects near singularity are studied here within a general space-time framework. A second-order nonlinear differential equation governs these effects in the vicinity of a strong-curvature singularity. The possibility of singularity avoidance is examined. It is seen that nonclassical, nonsingular states can occur with finite probability in the present scenario.
