Oops For The Loops: Mounting LQG Woes And A Challenge To The LGQ Community
Stephane Herman Maes · 2023
This paper results from work done on the multi-fold theory which resulted into a proposal for quantum gravity. 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, whether 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 a 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 (GR) at large scales, and semi-classical models remain valid till smaller scale than usually expected. Gravity, with non-negligible effects can therefore be added to the Standard Model resulting in what we defined as SMG. This can contribute to resolving several open issues with the Standard Model without New Physics other than gravity, i.e. no new particles or forces. These considerations hint at an even stronger relationship between gravity and the Standard Model.The multi-fold theory obviously overlaps and relates to other TOEs like superstrings and quantum gravity e.g.., Loop Quantum Gravity (LQG). Considerations about some of these other theories have been published, including lessons learned, and recommendations to fill gaps, or address issues. However, our initial analysis of LQG focused more on similarities, and our perceived gap in terms of particles, and entanglement modeling by LQG. We had not yet encountered an analysis, unrelated to the multi-fold theory, which argues that there would be a technical error in LQG quantization scheme that may also explain why LQG can’t recover GR, and a classical smooth spacetime so far. This argument may not have been explicitly published to, or discussed by, the LQG community.This paper points out and amplifies the arguments encountered around this possible error, and it challenges the LQG community to provide an answer, or a mitigating reformulated model.
