In a multi-fold universe, gravity emerges from Entanglement through the multi-fold mechanisms. As a result, gravity-like effects appear in between entangled particles that they be real or virtual. Long range, massless gravity results from entanglement of massless virtual particles. Entanglement of massive virtual particles leads to massive gravity contributions at very smalls scales. Multi-folds mechanisms also result into a spacetime that is discrete, with a random walk fractal structure and non-commutative geometry that is Lorentz invariant and where spacetime nodes and particles can be modeled with microscopic black holes. All these recover General relativity at large scales and semi-classical model remain valid till smaller scale than usually expected. Gravity can therefore be added to the Standard Model. This can contribute to resolving several open issues with the Standard Model without new Physics other than gravity. These considerations hints at a even stronger relationship between gravity and the Standard Model. In a multi-fold universe, we predicted that no spontaneous wave function collapse or decoherence is due to gravity induced spacetime or curvature superposition. It was at the difference of a widely held conjecture formalized by Penrose and Diósi. Experimental results seem to confirm that indeed gravity does not induce collapse by curvature superposition, albeit of course fluctuations and interactions could still result in collapse as with any other quantum interactions.
