Loop gravity theory
Web26 de dez. de 2005 · Though progress is being made in trying to at least draw observational consequences of loop quantum gravity, a theory of quantum gravity which arguably does make predictions (Amelino-Camelia, 2003, in the Other Internet Resources section below; D. Mattingly, 2005), it is remarkable that the most notable “test” of quantum … General relativity is the theory of gravitation published by Albert Einstein in 1915. According to it, the force of gravity is a manifestation of the local geometry of spacetime. Mathematically, the theory is modelled after Bernhard Riemann's metric geometry, but the Lorentz group of spacetime symmetries (an essential ingredient of Einstein's own theory of special relativity) replaces the group of rotational symmetries of space. (Later, loop quantum gravity inherited this geometric interpretati…

LQG is a method, it’s not a theory. Web16 de dez. de 2024 · The theory has no arbitrary assumptions and is only based on general relativity, quantum mechanics and compatibility with the standard model. The theory is well-defined even without supersymmetric particles. The "simple" structure of all that exits: The whole world consists of overlapping covariant quantum fields. Singularities do not occur.
WebLoop quantum gravity (LQG) is a theory of quantum gravity, which aims to merge quantum mechanics and general relativity, incorporating matter of the Standard Model into the framework established for the pure quantum gravity case.
