The main difference is that these quantum gravity studies assume the quantum laws to be set as fundamental laws. In such a framework, the fractal geometry of space-time at the Planck scale is a consequence of the quantum nature of physical… As the study of the statistical mechanics of black-body radiation led to the advent of the theory of quantum mechanics, the effort to understand the statistical mechanics of black holes has had a deep impact upon the understanding of… Since the supersymmetry (SUSY) generators form together with the Poincaré algebra a superalgebra, called the super-Poincaré algebra, supersymmetry a gauge theory makes gravity arise in a natural way. The equations governing ordinary gravity in free space can be obtained from an action, by applying the variational principle to a certain action. Some functional forms may be inspired by corrections arising from a quantum theory of gravity. f(R) gravity was first proposed in 1970 by Hans Adolph Buchdahl (although ϕ was used rather than f for the name of the arbitrary function).
Loop quantum gravity seriously considers general relativity's insight that spacetime is a dynamical field and is therefore a quantum object.
Tensor–vector–scalar gravity (TeVeS), developed by Jacob Bekenstein in 2004, is a relativistic generalization of Mordehai Milgrom's Modified Newtonian dynamics (MOND) paradigm.

covariant loop quantum gravity (covariant LQG). It is a theory that has grown historically via a long indirect path, brieﬂy summarized at the end of this chapter. The book does not follows the historical path. Rather, it is pedagogical, taking the reader through the steps needed to learn the theory.

Dynamics can be formulated in two ways in loop quan-tum gravity: in the canonical framework, via the de ni-tion of the quantum Hamiltonian constraint, and in the covariant framework, in terms of transition amplitudes expressed as \sums over geometries" called spinfoams. Loop quantum cosmology  has studied the problem Abstract: In this manuscript we present a calculation of a physical observable in a non-perturbative quantum gravitational physical process from covariant Loop Quantum Gravity. The process regards the transition of a trapped region to an anti--trapped region, treated as a quantum geometry transition akin to gravitational tunneling. It modifies our understanding of time, space and matter. The recent development of the loop approach has allowed us to explore domains ranging from black hole thermodynamics to the early Universe. This book provides readers with a simple introduction to loop quantum gravity, centred on its covariant approach.
