In Greek mythology, Aether (/ˈiːθər/; Ancient Greek: Αἰθήρ, Aither, pronounced [aitʰɛ̌ːr]) is one of the primordial deities. Aether is the personification of the "upper sky". He embodies the pure upper air that the gods breathe, as opposed to the normal air (ἀήρ, aer) breathed by mortals. Like Tartarus and Erebus, Aether may have had shrines in ancient Greece, but he had no temples and is unlikely to have had a cult.

|Parents||Erebus and Nyx (Hesiod) or|
Chronos and Ananke (Orphic Hymns) or
Chaos (Ovid, Hyginus)
|Siblings||Hemera, Hypnos, Thanatos, Eris (Hesiod), Clotho, Lachesis, Atropos, Apate, Nemesis, Eleos, the Keres, Hecate, Alecto (variant accounts), Megaera (variant accounts) , Tisiphone (variant accounts), Lyssa, Apate, Dolos, Momus, Moros, Oizys|
Hyginus says further that the children of Aether and Day were Earth, Heaven, and Sea, while the children of Aether and Earth were "Grief, Deceit, Wrath, Lamentation, Falsehood, Oath, Vengeance, Intemperance, Altercation, Forgetfulness, Sloth, Fear, Pride, Incest, Combat, Ocean, Themis, Tartarus, Pontus; and the Titans, Briareus, Gyges, Steropes, Atlas, Hyperion, and Polus, Saturn, Ops, Moneta, Dione; and three Furies – namely, Alecto, Megaera, Tisiphone."
Aristophanes states that Aether was the son of Erebus. However, Damascius says that Aether, Erebus and Chaos were siblings, and the offspring of Chronos (Father Time). According to Epiphanius, the world began as a cosmic egg, encircled by Time and Inevitability (most likely Chronos and Ananke) in serpent fashion. Together they constricted the egg, squeezing its matter with great force, until the world divided into two hemispheres. After that, the atoms sorted themselves out. The lighter and finer ones floated above and became the Bright Air (Aether and/or Uranus) and the rarefied Wind (Chaos), while the heavier and denser atoms sank and became the Earth (Gaia) and the Ocean (Pontos and/or Oceanus). See also Plato's Myth of Er.
The fifth Orphic hymn to Aether describes the substance as "the high-reigning, ever indestructible power of Zeus," "the best element," and "the life-spark of all creatures." Though attributed to the mythological poet Orpheus who lived before the time of Homer, the likely composition of the hymns in the 6th-4th centuries BCE make them contemporary with natural philosophers, such as Empedocles, who theorized the material forces of nature as identical with the gods and superior to the anthropomorphic divinities of Homeric religion.
Aither may refer to:
Aether (classical element), the material supposed to fill the region of the universe above the terrestrial sphere
Aether (mythology), the personification of the "upper sky", space and heaven, in Greek mythologyVacuum
Vacuum is space devoid of matter. The word stems from the Latin adjective vacuus for "vacant" or "void". An approximation to such vacuum is a region with a gaseous pressure much less than atmospheric pressure. Physicists often discuss ideal test results that would occur in a perfect vacuum, which they sometimes simply call "vacuum" or free space, and use the term partial vacuum to refer to an actual imperfect vacuum as one might have in a laboratory or in space. In engineering and applied physics on the other hand, vacuum refers to any space in which the pressure is lower than atmospheric pressure. The Latin term in vacuo is used to describe an object that is surrounded by a vacuum.
The quality of a partial vacuum refers to how closely it approaches a perfect vacuum. Other things equal, lower gas pressure means higher-quality vacuum. For example, a typical vacuum cleaner produces enough suction to reduce air pressure by around 20%. Much higher-quality vacuums are possible. Ultra-high vacuum chambers, common in chemistry, physics, and engineering, operate below one trillionth (10−12) of atmospheric pressure (100 nPa), and can reach around 100 particles/cm3. Outer space is an even higher-quality vacuum, with the equivalent of just a few hydrogen atoms per cubic meter on average in intergalactic space. According to modern understanding, even if all matter could be removed from a volume, it would still not be "empty" due to vacuum fluctuations, dark energy, transiting gamma rays, cosmic rays, neutrinos, and other phenomena in quantum physics. In the study of electromagnetism in the 19th century, vacuum was thought to be filled with a medium called aether. In modern particle physics, the vacuum state is considered the ground state of a field.
Vacuum has been a frequent topic of philosophical debate since ancient Greek times, but was not studied empirically until the 17th century. Evangelista Torricelli produced the first laboratory vacuum in 1643, and other experimental techniques were developed as a result of his theories of atmospheric pressure. A torricellian vacuum is created by filling a tall glass container closed at one end with mercury, and then inverting it in a bowl to contain the mercury (see below).Vacuum became a valuable industrial tool in the 20th century with the introduction of incandescent light bulbs and vacuum tubes, and a wide array of vacuum technology has since become available. The recent development of human spaceflight has raised interest in the impact of vacuum on human health, and on life forms in general.Wilhelm Reich
Wilhelm Reich (; German: [ʁaɪç]; 24 March 1897 – 3 November 1957) was an Austrian doctor of medicine and psychoanalyst, a member of the second generation of analysts after Sigmund Freud. The author of several influential books, most notably Character Analysis (1933), The Mass Psychology of Fascism (1933), and The Sexual Revolution (1936), Reich became known as one of the most radical figures in the history of psychiatry.Reich's work on character contributed to the development of Anna Freud's The Ego and the Mechanisms of Defence (1936), and his idea of muscular armour—the expression of the personality in the way the body moves—shaped innovations such as body psychotherapy, Gestalt therapy, bioenergetic analysis and primal therapy. His writing influenced generations of intellectuals; he coined the phrase "the sexual revolution" and according to one historian acted as its midwife. During the 1968 student uprisings in Paris and Berlin, students scrawled his name on walls and threw copies of The Mass Psychology of Fascism at police.After graduating in medicine from the University of Vienna in 1922, Reich became deputy director of Freud's outpatient clinic, the Vienna Ambulatorium. Described by Elizabeth Danto as a large man with a cantankerous style who managed to look scruffy and elegant at the same time, he tried to reconcile psychoanalysis with Marxism, arguing that neurosis is rooted in sexual and socio-economic conditions, and in particular in a lack of what he called "orgastic potency". He visited patients in their homes to see how they lived, and took to the streets in a mobile clinic, promoting adolescent sexuality and the availability of contraceptives, abortion and divorce, a provocative message in Catholic Austria. He said he wanted to "attack the neurosis by its prevention rather than treatment".From the 1930s he became an increasingly controversial figure, and from 1932 until his death in 1957 all his work was self-published. His message of sexual liberation disturbed the psychoanalytic community and his political associates, and his vegetotherapy, in which he massaged his disrobed patients to dissolve their "muscular armour", violated the key taboos of psychoanalysis. He moved to New York in 1939, in part to escape the Nazis, and shortly after arriving coined the term "orgone"—from "orgasm" and "organism"—for a biological energy he said he had discovered, which he said others called God. In 1940 he started building orgone accumulators, devices that his patients sat inside to harness the reputed health benefits, leading to newspaper stories about sex boxes that cured cancer.Following two critical articles about him in The New Republic and Harper's in 1947, the U.S. Food and Drug Administration obtained an injunction against the interstate shipment of orgone accumulators and associated literature, believing they were dealing with a "fraud of the first magnitude". Charged with contempt in 1956 for having violated the injunction, Reich was sentenced to two years imprisonment, and that summer over six tons of his publications were burned by order of the court. He died in prison of heart failure just over a year later, days before he was due to apply for parole.
