2. Aether theories - Wikipedia

   en.wikipedia.org/wiki/Aether_theories

   In the 19th century, luminiferous aether (or ether), meaning light-bearing aether, was a theorized medium for the propagation of light. James Clerk Maxwell developed a model to explain electric and magnetic phenomena using the aether, a model that led to what are now called Maxwell's equations and the understanding that light is an ...

3. Einstein-aether theory - Wikipedia

   en.wikipedia.org/wiki/Einstein-aether_theory

   These generally covariant theories describes a spacetime endowed with both a metric and a unit timelike vector field named the aether. The aether in this theory is "a Lorentz-violating vector field" [1] unrelated to older luminiferous aether theories; the "Einstein" in the theory's name comes from its use of Einstein's general relativity ...

4. Etheric plane - Wikipedia

   en.wikipedia.org/wiki/Etheric_plane

   The term aether (also written as "ether") was adopted from ancient Greek philosophy and science into Victorian physics (see Luminiferous aether) and utilised by Madame Blavatsky to correspond to akasha, the fifth element (quintessence) of Hindu metaphysics. The Greek word aither derives from an Indo-European root aith- ("burn, shine").

   According to ancient and medieval science, aether (/ ˈ iː θ ər /, alternative spellings include æther, aither, and ether), also known as the fifth element or quintessence, is the material that fills the region of the universe beyond the terrestrial sphere. [1]

7. Lorentz ether theory - Wikipedia

   And referring to the Fizeau experiment, he even wrote: "The aether is all but in our grasp." He also said the aether is necessary to harmonize Lorentz's theory with Newton's third law. Even in 1912 in a paper called "The Quantum Theory", Poincaré ten times used the word "aether", and described light as "luminous vibrations of the aether". [A 19]
