  We consider a Bohmian approach to the Wheeler-DeWitt quantization of the
Friedmann-Lemaitre-Robertson-Walker model and investigate the question whether
or not there are singularities, in the sense that the universe reaches zero
volume. We find that for generic wave functions (i.e., non-classical wave
functions), there is a non-zero probability for a trajectory to be
non-singular. This should be contrasted to the consistent histories approach
for which it was recently shown by Craig and Singh that there is always a
singularity. This result illustrates that the question of singularities depends
much on which version of quantum theory one adopts. This was already pointed
out by Pinto-Neto et al., albeit with a different Bohmian approach. Our current
Bohmian approach agrees with the consistent histories approach by Craig and
Singh for single-time histories, unlike the one studied earlier by Pinto-Neto
et al. Although the trajectories are usually different in the two Bohmian
approach, their qualitative behavior is the same for generic wave functions.
