An important feature of loop quantum cosmology is the effective space-time description of the underlying quantum evolution. [10] The effective dynamics approach has been extensively used in loop quantum cosmology to describe physics at the Planck scale and the very early universe.
New teleparallel gravity theory (or new general relativity) is a theory of gravitation on Weitzenböck spacetime, and attributes gravitation to the torsion tensor formed of the parallel vector fields. In the new teleparallel gravity theory the fundamental assumptions are as follows:
The theory claims to be consistent with both the macro-level observations of Newtonian gravity as well as Einstein's theory of general relativity and its gravitational distortion of spacetime. Importantly, the theory also explains (without invoking the existence of dark matter and tweaking of its new free parameters ) why galactic rotation ...
Moffat's work culminates in his nonsymmetric gravitational theory and scalar–tensor–vector gravity (now called MOG). [1] His theory explains galactic rotation curves without invoking dark matter. He proposes a variable speed of light approach to cosmological problems, which posits that G/c is constant through time, but G and c separately ...
The gauge-invariant perturbation theory is based on developments by Bardeen (1980), [7] Kodama and Sasaki (1984) [8] building on the work of Lifshitz (1946). [9] This is the standard approach to perturbation theory of general relativity for cosmology. [10]

According to Axe, the research he provides with his book disproves Darwin's theory of evolution, revealing "a gaping hole has been at its center from the beginning." Click through 10 books that ...
De Rham is recognised as a researcher at the forefront of the development of theories of massive gravity, where the particle carrier of the gravitational force, the graviton, may be massive. [14] In 2010, she constructed a nonlinear [clarification needed] theory of a massive graviton, which is theoretically consistent and ghost-free.
