Quantum Gravity Emergence from Entanglement in a Multi-Fold Universe

Abstract

We start from a hypothetical multi-fold universe U_MF, where the propagation of everything is slower or equal to ‎the speed of light and where entanglement extends the set of paths available to Path Integrals. This multifold ‎mechanism enables EPR (Einstein-Podolsky-Rosen) “spooky actions at distance” to result from local interactions ‎in the resulting folds. It produces gravity-like attractive effective potentials in the spacetime, between entangled ‎entities, that are caused by the curvature of the folds. When quantized, multi-folds correspond to gravitons and ‎they are enablers of EPR entanglement. Gravity emerges non-perturbative and covariant from EPR entanglement ‎between virtual particles surrounding an entity. In U_MF, we encounter mechanisms that predict gravity fluctuations ‎when entanglement is present, including in macroscopic entanglements. Besides providing a new perspective on ‎quantum gravity, when added to the Standard Model as (SMG), with non-negligible affects at its scales, and to the ‎Standard Cosmology, U_MF can contribute explanations of several open questions and challenges. It also clarifies ‎some relationships and challenges met by other quantum gravity models and Theories of Everything. It leads to ‎suggestions for these works. We also reconstruct the spacetime of U_MF, starting from the random walks of particles ‎in an early spacetime. U_MF now appears as a noncommutative, discrete, yet Lorentz symmetric, spacetime that ‎behaves roughly 2-Dimensional at Planck scales, when it is a graph of microscopic Planck size black holes on a ‎random walk fractal structure left by particles that can also appear as microscopic black holes. Of course, at larger ‎scales, spacetime appears 4-D, where we are able to explain curvature and recover Einstein’s General Relativity. We ‎also discover an entanglement gravity-like contributions and massive gravity at very small scales. This is ‎remarkable considering that no Hilbert Einstein action, or variations expressing area invariance, were introduced. ‎Our model also explains why semi classical approaches can work till way smaller scale than usually expected and ‎present a new view on an Ultimate Unification of all forces, at very small scales. We also explore opportunities for ‎falsifiability and validation of our model, as well as ideas for futuristic applications, that may be worth considering, ‎if U_MF was a suitable model for our universe U_real.‎
