摘要
In this essay, we argue that the emergence of classically connected space-times is intimately related to the quantum entanglement of degrees of freedom in a nonperturbative description of quantum gravity. Disentangling the degrees of freedom associated with two regions of space-time results in these regions pulling apart and pinching off from each other in a way that can be quantified by standard measures of entanglement.
