On the Dynamics between Gravity and Entanglement

Abstract

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 holds the assumption of a noncommutative space where the Requardt-Roy model seems to be a promising one. From the ordinary five-dimensional approach, first initiated by Kaluza and Klein, a toy model is proposed to show an insignificant description of gravity at Planck’s scale physics. It is found that the classical nature of quantum correlations is fine-tuned within the geometry of space-time in four dimensions. Such a nature can be better understood by studying the pregeometric effects of gravity in five dimensions. A combined description is found, sufficient to explain the fundamental difficulties of a discrete space-time manifold in both theories.
