  With the decline of the Copenhagen interpretation of quantum mechanics and
the recent experiments indicating that quantum mechanics does actually embody
'objective reality', one might ask if a 'mechanical', conceptual model for
quantum mechanics could be found. We propose such a model. Vacuum energy
fluctuations imply mass fluctuations and, through general relativity, curvature
fluctuations. And those fluctuations are indicated by fluctuations of the
metric tensor. The metric tensor fluctuations can 'explain' the uncertainty
relations and non-commuting properties of conjugate variables. We argue that
that the probability density is proportional to the square root of minus the
determinant of the metric tensor (the differential volume element). We argue
that the metric elements are not stochastic but are oscillating at a high
enough frequency that measured values of same appear stochastic (i.e.
crypto-stochastic). We suggest that the oscillations at the position of
particles are described as torsional vibrations. A crypto-stochastic (or
chaotic) oscillating metric yields, among other things, a model of
super-position, photon polarization, and entanglement, and all within the
confines of a 4-dimensional space-time.
