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. In particular with chirality flips of fermions induced by gravity, right-handed neutrinos (and left-handed anti-neutrinos) can appear in flight and now acquire mass when encountering Higgs bosons. Because perturbatively self-gravity effects may be stronger for anti-neutrinos, the chirality flips in flight will trap longer in flight right-handed anti neutrinos than left-handed neutrinos; creating a matter antimatter asymmetry. While very small this can explain the dominance of matter of antimatter, hence why we exist. As we visit the properties of antimatter, we also predict that, in a multi-fold universe, anti-matter is attracted by gravity, not repelled; something that is still an open issue today in Physics.
