19th century theories of luminiferous aether. Augustin-Jean Fresnel proposed a correction due to the motion of a medium (the aether) through which light propagated...

the theory of the luminiferous aether as the hypothetical medium for the propagation of light waves was widely discussed. The aether hypothesis arose because...

electromagnetic waves could travel in a vacuum without the need of a medium or luminiferous aether. Einstein also developed general relativity, in which spacetime was...

electromagnetism or light viewed as a disturbance of a "light medium" or luminiferous aether was widely accepted. The theory reached its most developed form in...

contraction of an object according to one frame (as defined by the luminiferous aether) produced a measurable effect in the rest frame of the object, so...

Orgone was seen as a massless, omnipresent substance, similar to luminiferous aether, but more closely associated with living energy than with inert matter...

The term aether (also written as "ether") was adopted from ancient Greek philosophy and science into Victorian physics (see Luminiferous aether) and utilised...

Michelson–Morley experiment of 1887 had suggested that the hypothetical luminiferous aether, if it existed, was completely dragged by the Earth. To test this...

Comet (and Comet Encke) had a role in the now-discredited concept of luminiferous aether: its orbit was found to be shrinking in size, which was ascribed...
