Ether Ether is or not? If we look at Wikipedia the word ether (and clearly not ether as an anesthetic), we find the following description: Ether (in ancient greek αθήρ, merged into Latin as aether), which stands for quintessence (from Medieval Latin quinta essentia, in turn, change the greek pémpton Stoicheion, Fifth Element), was an element that Aristotle is going to add up to four other well-known: fire, water, earth, air. According to the alchemists, the ether would be the main compound of the philosophers stone. The history of the ether begins with Aristotle, who was the essence of the celestial world, different from the four species (or items) that you thought made up the terrestrial world: earth, air, fire and water. Aristotle believed that the ether was eternal, immutable, weightless and transparent. Just for eternity and immutability of the ether, the cosmos was a place unchanging, as opposed to the Earth, a place of change. For the ancient ether was the most high, pure and bright, the space above the atmosphere. In the nineteenth century, the discovery of electromagnetic waves, ( Guglielmo Marconi ) coupled with the conviction that their transmission would require the support of a material medium, had taken up the ancient word, which, more than others, it is closer to the idea of property which means that it had to be fitted. The experience of Michelson-Morley has shown that one of the properties that the ether would have to possess according to that theory, its absolute immobility, was not true. It showed more than anything else it is pointless to the effects of wave propagation rather than the lack of it. The electromagnetic waves do not need any material medium to propagate. For them just the vacuum and, when you say spread over the air, the air is synonymous with vacuum. In this expression the ether resumes its former meaning, expanded the scientific knowledge accumulated is a word that means the atmosphere, its upper part which was added that there is still further: the cosmic void. Chronologically followed the theory of relativity by Albert Einstein greeted with enthusiasm by allowing academics to deliver forgotten the concept of ether as a substance imponderable concept obviously too cumbersome and tiring. There is, however, Guglielmo Marconi discovered electromagnetic waves just because he believed in the existence of ether and the exchange of energy that occurs between the sun and the earth, scientists and researchers who lived in the nineteenth century (as Nikola Tesla which will be given by the Supreme Court of the United States in 1943 with the invention of radio) knew the ether as the definition and existence! Science should never be ashamed of herself. So much so that if we see an old Encyclopedia, such as Pombal, in the year 1926, even under the slogan cosmic ether is written: extraordinary means, soft and elastic that permeates all of space and makes it the vehicle of shares distance, which could not otherwise justify. The first idea of the cosmic ether was launched by Descartes; supported and enforced to the wave theory of light by Huygens, took firm foundation in the physical sciences to work Joung, Fresnel, Faraday, and so on. The density of the ether and its elasticity to vary penetrating bodies, whatever their state of aggregation. And similarly in the Encyclopedia Motta, early 50s of the last century, writes: tenuous and imponderable substance that is the means of propagation of vibrations that characterize the phenomena of light and of what should be pregnant all the Universe. But today the ether is compared to the cosmic void, so the question nonè so whether or not there ether as: Is there a cosmic void or empty of all time? This poses the question if Marco Todeschini (1899 - 1988) and consequently leads to a further question: the movement of bodies is caused by the collision with other bodies or by pressing or by applying forces?
