  3. General relativity - Wikipedia

    en.wikipedia.org/wiki/General_relativity

    The same experimental data shows that time as measured by clocks in a gravitational field—proper time, to give the technical term—does not follow the rules of special relativity. In the language of spacetime geometry, it is not measured by the Minkowski metric. As in the Newtonian case, this is suggestive of a more general geometry.

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

    In special relativity, energy is closely connected to momentum. In special relativity, just as space and time are different aspects of a more comprehensive entity called spacetime, energy and momentum are merely different aspects of a unified, four-dimensional quantity that physicists call four-momentum. In consequence, if energy is a source of ...

  6. 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 ).

    Numerical relativity, a subfield of computational physics that aims to establish numerical solutions to Einstein's field equations in general relativity; Principle of relativity, used in Einstein's theories and derived from Galileo's principle; Theory of relativity, a general treatment that refers to both special relativity and general relativity

    became crucial. This type of performance evaluation required the definition of both particular standards and broader objectives in the pursuit of educational goals. Second, these standards and assessment-based reforms also included the involvement and feedback of various stakeholders in both the public and the private sector.

  9. World line - Wikipedia

    en.wikipedia.org/wiki/World_line

    The use of world lines in general relativity is basically the same as in special relativity, with the difference that spacetime can be curved. A metric exists and its dynamics are determined by the Einstein field equations and are dependent on the mass-energy distribution in spacetime.
