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 (SM) without new Physics other than gravity. These considerations hint at a even stronger relationship between gravity and the Standard Model.In past papers, we have argued that chirality flips can occur in the presence of non-negligible gravitational effects. In multi-fold universes, it led us propose mechanisms to justify the absence of proton decay and the possible existence in flight of right-handed neutrinos and left-handed anti-neutrinos. However, we based these proposals on helicity flips at scales above mass acquisition by the Higgs mechanisms. We did not discuss the obvious implications on conservation of the weak hypercharge or weak isospin. This paper does so.The chirality flips of massless particles above the multi-fold gravity electroweak symmetry breaking energy scale can be attributed to spacetime orientation fluctuations, as particle appear.
