    en.wikipedia.org/wiki/Quantum_gravity

    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.

  5. Loop quantum gravity - Wikipedia

    en.wikipedia.org/wiki/Loop_quantum_gravity

    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 ...

  6. History of loop quantum gravity - Wikipedia

    en.wikipedia.org/wiki/History_of_loop_quantum...

    (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 ...

    Quantum gravity, a theory in physics that aims to unify general relativity and quantum mechanics; Quasigeostrophic, an atmospheric dynamics theory; see Geostrophic wind; Quadrature Generator; see quadrature amplitude modulation; Nissan QG engine, an automotive engine series

  8. Canonical quantum gravity - Wikipedia

    en.wikipedia.org/wiki/Canonical_quantum_gravity

    The problem of quantum cosmology is that the physical states that solve the constraints of canonical quantum gravity represent quantum states of the entire universe and as such exclude an outside observer, however an outside observer is a crucial element in most interpretations of quantum mechanics. [clarification needed]

  9. Graviton - Wikipedia

    en.wikipedia.org/wiki/Graviton

    In string theory, believed by some to be a consistent theory of quantum gravity, the graviton is a massless state of a fundamental string. If it exists, the graviton is expected to be massless because the gravitational force has a very long range, and appears to propagate at the speed of light.
