Loop quantum gravity (LQG) is a theory of quantum gravity that incorporates matter of the Standard Model into the framework established for the intrinsic quantum gravity case. It is an attempt to develop a quantum theory of gravity based directly on Albert Einstein 's geometric formulation rather than the treatment of gravity as a mysterious ...
The loop representation is a quantum hamiltonian representation of gauge theories in terms of loops. The aim of the loop representation in the context of Yang–Mills theories is to avoid the redundancy introduced by Gauss gauge symmetries allowing to work directly in the space of physical states (Gauss gauge invariant states).
Causal dynamical triangulation (CDT), theorized by Renate Loll, Jan Ambjørn and Jerzy Jurkiewicz, is an approach to quantum gravity that, like loop quantum gravity, is background independent. This means that it does not assume any pre-existing arena (dimensional space) but, rather, attempts to show how the spacetime fabric itself evolves.
The force between quarks is known as the colour force [6] (or color force [7]) or strong interaction, and is responsible for the nuclear force. Since the theory of electric charge is dubbed "electrodynamics", the Greek word χρῶμα (chrōma, "color") is applied to the theory of color charge, "chromodynamics".

The various hypothetical design models for the universe, multiverse, and loop quantum gravity could have various general covariant principle results. Because loop quantum gravity can model universes, space-gravity theories are contenders to build and answer unification theory. The Lorentz invariance helps grade the spread of universal features ...
(Later, loop quantum gravity inherited this geometric interpretation of gravity, and posits that a quantum theory of gravity is fundamentally a quantum theory of spacetime.) In the 1920s, the French mathematician Élie Cartan formulated Einstein's theory in the language of bundles and connections, [ 1 ] a generalization of Riemannian geometry ...
