Since great mind since since the beginning of the history, a smooth lacerate is muddleheaded, was born from now on the boundless universe. People is comprised from what there is the universe before early, after all is this flourishing world everythings on earth by what comprise? It is smooth above all! " Bible " in god created light in the first day, it is important that visible light has many, indicative hope.
China has the theory of the five elements of earth of golden wood extreme misery, so-called universe everythings on earth all is in the five elements. And very artful is, gu Xila's Yalishiduode, also offerred similar theory, he says, the element that constitutes material is mixed for water, fire, gas, earth aether. Before 4 kinds we are very good understand, so what thing is aether?
Ancient periodAether most in the doctrine that appears at Yalishiduode first. Most first, people thinks the source of everythings on earth is water, aquatic everythings on earth, ancient later Babylonian person and Egyptian think of the earth this -- earth also is, and form us the gas all around also is. Anakeximande gives nap this view, introduce fire, formed 4 large elements from now on say. And Yalishiduode feels, worldly still put in a kind of basic material, it lives in celestial superstratum, it is cosmic essence, it is called " aether " !
But aether is too windy really, the likelihood is a philosophical sect in the Wei and Jin dynasties, know without the person it is long what kind of, it is what thing. Aether was forgotten very quickly by people, the view of Europe is long-term also and popular 4 large elements, be not 5 large elements.
Modern science is budding periodThen, generation great mind -- Cartesian appeared, he entered aether area scientific world single-handed. Bovine knight returns be pregnant with to be in scientific cradle at that time, scientific rainstorm should come then eventually, and Cartesian it is this stormy person that start. Astronomy is watched on him, jiang Hai is watched below, think to there is a kind of material all the time in this universe, like be with respect to life resembling a fish in water, do not jump out surface, won't know forever all round return existence water this kind of material. He drew the concept of aether, those who think Yalishiduode says is right, put in aether really, and, it is the agency of all active force! No matter be magnetic force or moon to tidal appeal, be delivered through aether, and think force is not exceed those who spur action. (namely force is delivered is not instantaneous, it is to pass intermediary)
But later, people discovers the square of gravitation and distance becomes inverse ratio, be apart from namely in other words further, force is weaker, and it is the concern that becomes square, the instant will Cartesian " aether " strangled.
Newton and introduced from the northern and western nationalities or from abroad gram are big battle periodTime comes to bovine knight one branch alone beautiful 17 centuries, at that time, the debate that is wave or particle solely is formal open. Hooker (invent microscope namely that) , regard optics as a party to an undertaking of the bound, put forward light this kind of material, it is a kind of wave! But wave it is the intermediary that need delivers, this kind of agency, it is the aether that nowhere is absent!
Newton does not agree apparently, he took out the smooth chromatic dispersion test of prism, plus oneself that as the identity with physical group average spirit, particle of his stand in line says. But Newton did not abandon aether however, he thinks aether exists really, be refracted solely and reflex a phenomenon, because the systole of aether is mixed,be likely expand cause.
Although war of two National People's Congress lasted very long, and mutual open group ridicule mode, but advance rapidly of science of that paragraph of time, two people take credit to oneself very Wei.
Mahayana periodTime comes to 19 centuries, phenanthrene Nie ear and the wave motion that hold Ma Siyang in the palm to put forward light say theory, said in order to fluctuate to explain interference, diffractive, birefraction, polarization, smooth even linear transmission phenomenon successfully. These explanations make light fluctuant say scene is not had for a short while 2, and the agency of smooth transmission -- aether was proved by people with respect to difference! Want it to exist only, can say everything to connect!
RuinedEinstein came to great mind eventually, he is enrolled with respect to enlarge -- relativistic, direct a velocity of light is changeless served as a fundamental, aether this is planted material from worldly move besides. Because the basis is fluctuant, wave be the attenuation in can transmitting a process, and velocity of light is changeless, direct aether this kind of material sentenced capital punishment!
Later period quanta is mechanical it is to cast more gave wave bead dual property, the source of the windy universe in that fokelore " aether " , was abandoned by the world then eventually.
