Entanglement, Causality and the Cohesion of Spacetime

Entanglement is an extraordinary quantum mechanical property where two particles remain connected to one another, no matter how far apart they may be in the universe. Far from simply being a curiosity, entanglement may exist across time and provide not only cohesion to space-time, but also a primordial scaffold for causal links. This suggests the existence of symmetrical relations between events separated in time and raises the possibility that the future may influence the past.
