completely different predictions. relativity predictions match experiment, ether predictions don't.

In Huygens' wave theory of light, ether (or "luminiferous ether") was a hypothetical medium through which light waves were thought to propagate. Huygens proposed that every point on a wavefront serves as a source of secondary wavelets, which spread out in all directions, creating the wave's propagation through this ether. Although ether was a widely accepted concept in the 19th century, it was later discarded after experiments, such as the Michelson-Morley experiment, failed to detect it, leading to the development of the theory of relativity.
yes
That may be an old term for an electromagnetic wave. The "ether" is the hypothetical substance through which electromagnetic waves travel; according to modern theory, the "ether" doesn't exist, at least, not with all the properties originally proposed. Empty space itself can be said to be the "ether", but the term is considered obsolete.
Experiments conducted in the late 19th century, particularly the Michelson-Morley experiment, aimed to detect the presence of "ether," a hypothesized medium for light propagation. The results showed no significant difference in the speed of light in different directions, contradicting the ether theory. This led to the conclusion that light does not require a medium to travel, ultimately contributing to the development of Einstein's theory of relativity, which posits that the speed of light is constant in a vacuum, independent of the observer's motion.
Petroleum ether and methanol are not very compatible solvents and tend to separate into distinct layers when mixed. Therefore, they do not mix well together and are considered immiscible. It is best to use them separately for different applications.
Ether in a cup or bowl lol
The results of the Michelson-Morley experiment did not fit the theory of the luminiferous ether, so the theory had to be rejected.
No, ethyl acetate and diethyl ether are not the same. Ethyl acetate is an ester commonly used as a solvent, while diethyl ether is an ether used as a solvent and a reagent in chemical reactions. They have different chemical structures and properties.
Though they are very similar to ethers, they are not ethers. They're sulfides.
ether or not slaves could be considered citizens
The modern spelling is 'ether'. The classical spelling from antiquity is 'aether'. A substance such as ethyl ethyl ether is CH3CH2 - O - CH2CH3
