  Recent developments on Bell's experiments demonstrate that entanglement could
indeed eliminate the gap between classical and quantum physics. At the same
time, it is difficult for a classical theory to include a particular feature
like entanglement without compromising the theory's smooth working on a
four-dimensional scale geometry. A unified theory should reconsider this
difficulty. On the other hand, pregeometry hold the assumption of a
non-commutative space where the Requardt-Roy model seems to be a promising one.
From the ordinary five-dimensional approach first initiated by Kaluza-Klein, a
toy model is proposed to show the insignificant description of gravity at
Planck's scale physics. It is found that the classical nature of quantum
correlations are fine tuned within the geometry of space-time at four
dimensions. Such a nature can be better understood by studying the pregeometric
effects of gravity at five-dimensions. A combined description of gravity and
entanglement is found sufficient to explain the fundamental difficulties of
discrete space-time manifolds in both the theories.
