Light is a wave, and the ''luminiferous aether'' (or ether) is defined to be whatever medium transmits the light waves.
Light is a wave, and at one time it was postulated that the ''luminiferous aether'' (or ether) is defined to be whatever medium transmits the light waves.
The [[Michelson-Morley experiment]] in 1887 failed to detect the aether. [[Henri Poincaré]] conjectured that the aether may be unobservable, and invented special [[relativity]] based on the notion that the aether may be superfluous. [[Albert Einstein]] published conflicting opinions on whether the aether exists.
