  2. Aether theories - Wikipedia

    en.wikipedia.org/wiki/Aether_theories

    As historians such as John Stachel argue, Einstein's views on the "new aether" are not in conflict with his abandonment of the aether in 1905. As Einstein himself pointed out, no "substance" and no state of motion can be attributed to that new aether. [10] Einstein's use of the word "aether" found little support in the scientific community, and ...

  3. Special relativity - Wikipedia

    en.wikipedia.org/wiki/Special_relativity

    The results of various experiments, including the Michelson–Morley experiment in 1887 (subsequently verified with more accurate and innovative experiments), led to the theory of special relativity, by showing that the aether did not exist. [20] Einstein's solution was to discard the notion of an aether and the absolute state of rest.

    1903 – Olinto De Pretto presents his aether theory with some form of mass–energy equivalence. [15] It was described by a formula looking like Einstein’s E = mc 2, but with different meanings of the terms. 1903 – Frederick Thomas Trouton and H.R. Noble publish the results of their experiment with capacitors, showing no aether drift. [16 ...

  5. History of special relativity - Wikipedia

    en.wikipedia.org/wiki/History_of_special_relativity

    Einstein's paper includes a fundamental description of the kinematics of the rigid body, and it did not require an absolutely stationary space, such as the aether. Einstein identified two fundamental principles, the principle of relativity and the principle of the constancy of light (light principle), which served as the axiomatic basis of his ...

  7. Einstein field equations - Wikipedia

    en.wikipedia.org/wiki/Einstein_field_equations

    The study of exact solutions of Einstein's field equations is one of the activities of cosmology. It leads to the prediction of black holes and to different models of evolution of the universe. One can also discover new solutions of the Einstein field equations via the method of orthonormal frames as pioneered by Ellis and MacCallum. [22]

    1. First postulate (principle of relativity) The laws of physics take the same form in all inertial frames of reference.. 2. Second postulate (invariance of c) . As measured in any inertial frame of reference, light is always propagated in empty space with a definite velocity c that is independent of the state of motion of the emitting body.
