The geometry of the Einstein-Rosen bridge presents the possibility of entanglement of nonlocal black hole event horizons. The historical difficulty in the nature of these hypersurface bridges has been singularity which was shown to destabilize the spacetime throat, preventing their prolonged existence. Singularity is based upon the Eddington-Finkelstein coordinate system and is exclusively reliant upon such a transformation of the Schwarzschild metric to be viable. Comparisons between specially and generally relativistic event horizons can demonstrate that such a transformation is not necessary to define a gravitationally bound event horizon and that a field free of singularity may yield negatively curved hypersurface geometry unbounded by eminent singularity collapse. The concept of quantum foam when applied to the principle of the Einstein-Rosen bridge may produce multiple hypersurfaces from a single such black hole. This bears the possibility that Poly-Entanglement may occur between clusters of black holes. Such physical behavior, while beyond conventional detection shows potential as an explanation for the galactic clustering and rotation behavior currently thought to be the result of dark matter.
