  2. Einstein-aether theory - Wikipedia

    en.wikipedia.org/wiki/Einstein-aether_theory

    In physics the Einstein-aether theory, also called aetheory, is the name coined in 2004 for a modification of general relativity that has a preferred reference frame and hence violates Lorentz invariance. These generally covariant theories describes a spacetime endowed with both a metric and a unit timelike vector field named the aether.

  3. 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 ...

  4. Light-dragging effects - Wikipedia

    en.wikipedia.org/wiki/Light-dragging_effects

    Einstein showed how the velocity of light in a moving medium is calculated, in the velocity-addition formula of special relativity. Einstein's theory of general relativity provides the solution to the other light-dragging effects, whereby the velocity of light is modified by the motion or the rotation of nearby masses.

  5. 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.

  6. Exact solutions in general relativity - Wikipedia

    en.wikipedia.org/wiki/Exact_solutions_in_general...

    Given the difficulty of constructing explicit small families of solutions, much less presenting something like a "general" solution to the Einstein field equation, or even a "general" solution to the vacuum field equation, a very reasonable approach is to try to find qualitative properties which hold for all solutions, or at least for all ...

  7. Tests of special relativity - Wikipedia

    en.wikipedia.org/wiki/Tests_of_special_relativity

    The idea that the aether might be completely dragged within or in the vicinity of Earth, by which the negative aether drift experiments could be explained, was refuted by a variety of experiments. Oliver Lodge (1893) found that rapidly whirling steel disks above and below a sensitive common path interferometric arrangement failed to produce a ...

  8. Relativity priority dispute - Wikipedia

    en.wikipedia.org/wiki/Relativity_priority_dispute

    p. 40: "The cradle of special theory of relativity was the combination of Maxwellian electromagnetism and the electron theory of Lorentz (and to a lesser extent of Larmor) based on Fresnel's notion of the stationary aether…. It is well known that Einstein's special relativity was partially motivated by this failure [to find the aether wind ...

  9. History of classical field theory - Wikipedia

    en.wikipedia.org/wiki/History_of_classical_field...

    Einstein developed the Einstein field equations of general relativity in 1915, consistent with special relativity and that could explain gravitation in terms of a field theory of spacetime. This removed the need of a gravitational aether. In 1918, Emmy Noether publishes the her theorem on the relations between symmetries and conservation laws. [17]
