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).

Effective quantum gravity observables and locally covariant QFT Among possible approaches, the most popular ones are the loop quantum gravity and the string theory. Despite the efforts of many decades the full theory of quantum gravity (QG) has not yet been established and the questions we face are of both technical
This procedure is basic to theories of particle physics, nuclear physics, condensed matter physics, and quantum optics. In particle physics, quantum field theory in curved spacetime is an extension of standard, Minkowski space quantum field theory to curved spacetime. Tensor–vector–scalar gravity (TeVeS), developed by Jacob Bekenstein in 2004, is a relativistic generalization of Mordehai Milgrom's Modified Newtonian dynamics (MOND) paradigm.

Quantum gravity is among the most fascinating problems in physics. 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 Download full-text PDF.
