The quantum source of space-time

Many physicists believe that entanglement is the essence of quantum weirdness — and some now suspect that it may also be the essence of space-time geometry.

Good idea, wish I'd thought of it... ;)

It might follow from some reflection on knot theory already.

Something similar follows from the mechanist hypothesis in cognitive science. It makes the physical reality NOT simulable by a Turing machine, and it makes the physical reality emerging from infinity of simulations, which are realized by the elementary arithmetical truth. This leads to a derivation of physics from the laws of number self-reference, in a testable way, as I have explained here. Advantage: we don't need the mathematical hypothesis, as this is derived too, and we don't need more than the arithmetical reality (the whole of mathematics is not amenable to a mathematical treatment). The quantum source itself is explained by the elementary properties and relations among natural numbers.

The paper above suggest that space-time might be more easy to derive from arithmetic than we might think. Certainly interesting.

That's very interesting, although about half way through my brain started to feel like chewing gum that had been stretched too far (the new analogy .... hmm .... whatever happened to those rubber sheets physicists used to like so much?)

Quantum entanglement is everywhere, I believe, so there must be an awful lot of wormholes around. Plus do they form and vanish when particles are entangled/disentangled?
