No Gravity Shield in Multi-folds Universes

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. The presence of a matter obstacle or shield on the path of the entangled virtual photons may be understood as weakening the gravity perceived beyond or within by a test particle. It is an incorrect conclusion. The potential energy (momentum 4-vector) of the shield and the shield acting a new source ensure that gravity perceived by the test particle is unaffected (other than by the additional contributions due to the proper gravity of the shield). In a multi-fold universe, Faraday cages do not weaken gravity!
