  2. General relativity - Wikipedia

    en.wikipedia.org/wiki/General_relativity

    This suggests the definition of a new class of inertial motion, namely that of objects in free fall under the influence of gravity. This new class of preferred motions, too, defines a geometry of space and time—in mathematical terms, it is the geodesic motion associated with a specific connection which depends on the gradient of the ...

  3. Theory of relativity - Wikipedia

    en.wikipedia.org/wiki/Theory_of_relativity

    The term "theory of relativity" was based on the expression "relative theory" (German: Relativtheorie) used in 1906 by Planck, who emphasized how the theory uses the principle of relativity. In the discussion section of the same paper, Alfred Bucherer used for the first time the expression "theory of relativity" (German: Relativitätstheorie ...

  4. ADM formalism - Wikipedia

    en.wikipedia.org/wiki/ADM_formalism

    It separates the spacetime metric into its spatial and temporal parts, which facilitates the study of the evolution of gravitational fields. The basic idea is to express the spacetime metric in terms of a lapse function that represents the time evolution between hypersurfaces, and a shift vector that represents spatial coordinate changes ...

  5. Introduction to general relativity - Wikipedia

    en.wikipedia.org/wiki/Introduction_to_general...

    Special relativity introduced a new framework for all of physics by proposing new concepts of space and time. Some then-accepted physical theories were inconsistent with that framework; a key example was Newton's theory of gravity, which describes the mutual attraction experienced by bodies due to their mass.

  6. Cosmological perturbation theory - Wikipedia

    en.wikipedia.org/wiki/Cosmological_perturbation...

    This is the standard approach to perturbation theory of general relativity for cosmology. [10] This approach is widely used for the computation of anisotropies in the cosmic microwave background radiation [ 11 ] as part of the physical cosmology program and focuses on predictions arising from linearisations that preserve gauge invariance with ...

  7. Reinventing Gravity - Wikipedia

    en.wikipedia.org/wiki/Reinventing_Gravity

    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 ...
