In this essay based on 0907.2939, we argue that the emergence of classically connected spacetimes is intimately related to the quantum entanglement of degrees of freedom in a non-perturbative description of quantum gravity. Disentangling the degrees of freedom associated with two regions of spacetime results in these regions pulling apart and pinching off from each other in a way that can be quantified by standard measures of entanglement.

My "cognitive white noise generator" has been locked on emergent spacetime for a decade now. The idea here, and I'm very loosely summarizing, is that the dimensions themselves are emergent properties of large scale entanglement - the mathematical "dimensions" resolve quite well…
One of the most important papers in this field is [0]. (As is common in science, it built on a long history of nearby ideas, e.g. [1].) An important calculation done around this idea is presented in [2], in which remarkable progress is made on Hawking's black hole information…
I think SW became too obsessed with the mathematical and computational approach to CA, while (as usual) 't Hooft pursued his physics intuitions to create a candidate CA theory: https://arxiv.org/abs/1405.1548 I say as usual, because G'tH had already formulated the holographic…
The links to the original papers: older one: http://arxiv.org/abs/1005.3035v1 recent one: http://arxiv.org/abs/1306.0533 Very cool. The paper suggests a connection between the non-local properties of EPR pairs and the non-local properties of wormholes that connect distant…
