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 ...
(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 ...
Abhay Vasant Ashtekar (born 5 July 1949) is an Indian theoretical physicist who created Ashtekar variables and is one of the founders of loop quantum gravity and its subfield loop quantum cosmology. [2] Ashtekar has also written a number of descriptions of loop quantum gravity that are accessible to non-physicists.
This is a list of notable researchers in the physics field of loop quantum gravity. Abhay Ashtekar, Pennsylvania State University, United States; John Baez, University of California, Riverside, United States; Aurélien Barrau, Université Grenoble Alpes, Grenoble, France; John W. Barrett, University of Nottingham, United Kingdom
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 ...
The distinguishing feature of LQC is the prominent role played by the quantum geometry effects of loop quantum gravity (LQG). In particular, quantum geometry creates a brand new repulsive force which is totally negligible at low space-time curvature but rises very rapidly in the Planck regime , overwhelming the classical gravitational ...
Quantum gravity (QG) is a field of theoretical physics that seeks to describe gravity according to the principles of quantum mechanics.It deals with environments in which neither gravitational nor quantum effects can be ignored, [1] such as in the vicinity of black holes or similar compact astrophysical objects, as well as in the early stages of the universe moments after the Big Bang.
