Aether

The aether (also spelled ether) is a substance concept, historically used in science and philosophy.

History of Science

In physics and philosophy, aether was once believed to be a substance which filled all of space. Aristotle included it as a fifth element on the principle that nature abhorred a vacuum. Aether was also called "Quintessence".

Oliver Nicholson points out that the older concept the aether (in contrast to the more well known luminiferous aether of the 19th century) had three properties. Among these characteristics, the aether had a non-material property, was "less than the vehicle of visible light", and was responsible for "generating metals" along with fostering the development of all bodies. [1] Robert Fludd stated that the aether was of the character that it was "subtler than light". Fludd cites the 3rd century view of Plotinus, concerning the aether as penetrative and non-material.[2] Other 1800s views, such as James Clerk Maxwell, Lord Kelvin, and Nikola Tesla, was of the disposition that the aether was more akin to it actually being the electromagnetic field.

The luminiferous aether of the more well known 19th century invocation was a concept held by some physicists and was an attempt to reconcile electromagnetic theory and Newtonian physics. This meaning of a "signal-carrying medium" is the origin of the name Ethernet. In modern physics the concept of fields even in an absolute vacuum devoid of all particulate matter remains, with terms such as "space-foam ", "Planck particles", "quantum wave state " (QWS), Zero-point energy, Dark energy, and Vacuum energy frequently used.

Fifth element


The aither ("aether") is another mysterious concept related to fire. This Greek concept seems to derive directly from the akasha, its Hindu counterpart. The aither is the fifth element, together with the four others: Fire, Earth, Air, Water. Aither would correspond to Celestial Fire. These five elements are not the ones which form the world, but the ones which destroy it: fire (conflagrations); water (floods); air (winds and hurricanes); earth (earthquakes). In this connection, it seems that aither is radiative heat like the one of the sun, etc., which is able to propagate in empty space.

The doctrine of the Four (or Five) Elements is ancient in Greece, where it dates from pre-Socratic times. But it is far older in the Far East, and was widely disseminated in India and China, where it forms the basis of both Buddhism and Hinduism, particularly in an esoteric context. The Greek word aither derives from an Indo-European radix aith- ("burn, shine"). This radix figures in the name of Aithiopia (Ethiopia), which means something like "burnt land".

In Greek doctrines it seems that the aither was the celestial fire, the pure essence where the gods lived and which they breathed.

Greek mythology


Aether ("upper air"), in Greek mythology, was the personification of the "upper sky", space and heaven. He is the pure, upper air that the gods breathe, as opposed to "aer", which mortals breathed. He was the son of Erebus and Nyx, and brother of Hemera. He is the soul of the world and all life emanates from him. The aether was also known as Zeus defensive wall; the bound that locked Tartaros from the cosmos.
