Query: Indeterministic Quantum Gravity and Cosmology VII. Dynamical Passage
  through Singularities: Black Hole and Naked Singularity, Big Crunch and Big
  Bang   This paper is a continuation of the papers [gr-qc/9409010, gr-qc/9505034,
gr-qc/9603022, gr-qc/9609035, gr-qc/9609046, gr-qc/9704033]. The aim of the
paper is to incorporate singularities---both local (black hole and naked
singularity) and global (big bang and big crunch)---into the dynamics of
indeterministic quantum gravity and cosmology. The question is whether a
singularity is dynamically passable, i.e., whether a dynamical process which
ends with a singularity may be extended beyond the latter. The answer is yes. A
local singularity is trivially passable, while the passableness for a global
singularity may invoke CPT transformation. The passableness of the
singularities implies pulsating black holes and the oscillating universe. For
the local singularity, the escape effect takes place: In a vicinity of the
singularity, quantum matter leaves the gravitational potential well.
  Keywords: tempered singularity, strong singularity, trivial passage, CPT
passage, pulsating black hole, escape effect, oscillating universe
