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, such as in the vicinity of black holes or similar compact astrophysical objects, such as … See more Much of the difficulty in meshing these theories at all energy scales comes from the different assumptions that these theories make on how the universe works. General relativity models gravity as curvature of See more There are a number of proposed quantum gravity theories. Currently, there is still no complete and consistent quantum theory of gravity, and the candidate models still need to overcome major formal and conceptual problems. They also face the common problem … See more • De Sitter relativity • Dilaton • Doubly special relativity • Gravitational decoherence • Gravitomagnetism See more Graviton The observation that all fundamental forces except gravity have one or more known See more As was emphasized above, quantum gravitational effects are extremely weak and therefore difficult to test.
