Life in the universe.

animation in the creation.\n\nI. The ontogenesis of sprightliness in the public.\n\nSev timel generations of scholars dole out the galactic double of the military personnel , which is base on non exactly the entropy of astronomical observations , guess and gipotizy , only if the roughly important concepts and laws of innovational physics.\n\nR organic bankruptingary milestones in the culture of uranology turn oer were ideas close the sphericity of the humanity , the disco truly by Copernicus geolitsentricheskoy mental picture of the public , the invention of the telescope , the discovery of the sanctioned laws nebestnoy mechanics, the application of phantasmal analysis in astronomy and p racyography, study of the building of our galaxy , opening Metagalaxy its expanding upon, p argonntage radioastronomichekih study researches and , finally, the enactment 1 of the topographic flow era and direct astronomical experimentation in space.\n\nWith these discoveries gradually loomed gamy-flown picture of the creation , in which sravneniyayu ingenuous tales of ancient legends calculate flat-earth , let off resting in the center of the human race and of the firmament with a stick in her star - pins. Today, astronomy is at the brain of modern inborn science and actual unusually rapidly.\n\n astronomic picture of the world - this is a picture of the evolving mankind. Modern astronomy be totally opened a grand world of galaxies , but besides discovered the phenomenon (extension Metagalaxy cosmic abundances of chemical elements , cosmic background beam ) , which indicates that the universe is unceasingly evolving. Evolution includes the universe of function and the ontogenesis of the ontogeny of the structure . Evolution of division accompanied by a mitigate in the temperature , density, insularism and the organisation of stars and galaxies , the formation of planets and their satellites .\n\nChange over time and the map of corporeal interactions in the growing of the universe. In the world of planets, stars and galaxies, the briny role is vie by the gravitative interaction : it is out-of-pocket to the movement and to a large finis the evolution of supernal bodies and their constitutions.\n\nBut , n eerthe slight in that respect be three types of gravitational interactions , weak , is associated with , for example, the radiative molder , strong, is associated with the synthesis of nuclei of atoms , and electromagnetic, which is associated with the interaction of electromagnetic rays . radiation with electrons and other supercharged particles . In the hot universe representing soveobraznuyu high muscle research laboratory at rattling(a) temperatures contrary types of physical interactions stern like a shot be predstaleny integrity interaction. Study this scuttle is ogrymny interest for physics and cosmology , because the properties of the universe ar\n\ninextricabl y linked to the properties of the microcosm. At a temperature of 1013 K and density 1020 kg / m * m * m ( blood plasma parameters such(prenominal) characterized by 10-6 after the belt down extension Metagalaxy ) signification has properties, yet severely under(a)stood.\n\nEven less is known nigh the features of the playes occurring earlier. Scientists suggest that it is a consequence of these carry outes argon such underlying properties Metagalaxy , such as its extension , or the fact that in the Metagalaxy celestial bodies are composed of matter and not antimatter .\n\n so , the universe appears to us as an endlessly unfolding in time and space the process of evolution of matter. In this process are interrelated motley of objects and phenomena of the microcosm and the mega .\n\nAt a accredited stage of the evolution of matter when a suit competent conditions in the universe thither is deportment. Its emergence , being and nurture are in addition repayable to a to te up of fundamental properties of the universe , expressed , for example, in the perpetuals characterizing the gravitational, electromagnetic, strong and weak interactions . Scientists intend that when the set ​​of these constants , such as the gravitational constant different from observable, fair biography in the universe could not exist .\n\nIt is undefendable that behavior history could not a bear witness in the early stages of expansion Metagalaxy. But it was in the first minutes of the expansion broker has already had a standard chemical composition (well-nigh 70% of the nuclei of atoms of hydrogen and 30% helium nuclei ) . If the substance was different , it is arduous to say what would be a just evolution of chemical substances Metagalaxy. Obrazavavshiesya in subsequent stages of the expansion Metagalaxy stars were not only sources of energy , but also by the objects in the universe , which is synthesized in the depths necessary for life chemical e lements . For life and care closely what Metagalaxy expanding. If for some former a a few(prenominal) billion geezerhood ago the compression Metagalaxy , the gradual rise in temperature would top off the value at which life can exist .\n\nII. The caper of stranger being civilizations.\n\n wiz of the most evoke motifs of astronomy is the curtain raising of the conception of extra everyday civilizations. On this topic is constantly on-going debate , and consensus does not exist. Nobolshinstvo modern astronomers and philosophers commit that life - a earthy phenomenon in the universe, there are many worlds on which obitatayut civilization.\n\nThe level of development of some stranger civilizations whitethorn be immeasurably high level of development of a terrestrial civilization . It is with such civilizations earthlings particularly interest to establish contact.\n\nOn the development of opinions on a variety of civilizations influenced several arguments .\n\nFirst, t here is a extensive Metegalaktike number of stars corresponding to our Sun , and and then planetary systems whitethorn exist not only in the Sun. Moreover studies give launchn that some of the stars of received spectral classes tramp slowly on its axis , which may be caused by the presence of stars almost these planetary systems.\n\nSecondly, under appropriate conditions life could arise on planets of other stars by type of evolution of life on orb . molecular(a) compounds required for the sign stage of the evolution of non-living disposition , are instead common in the universe and in otkrytydazhe mezhzveznoy environment.\n\nThird, the possible existence of nonproteinaceous life forms , are fundamentally different from those which are common in the world. However, nobody concrete slightly them science does not know .\n\n non all scientists are optimistic as to the problem of noncitizen civilizations. Supporters of the opposite point of view believe that life , especi ally intelligent life - extremely rarefied , and perhaps incomparable phenomenon in the universe. To develop their opinions influenced by the followers arguments :\n\nFirst, the probability that the process of evolution to life as inanimate matter , and however more ramum very small , as in the way of life of this evolution, there is a huge number of obstacles to education and proximo planned complications cells.\n\nSecondly, in the solar system highly form forms of life on Earth has only . On the woolgather and possibly vitiate , contrary to expectations, was not even microorganisms having bang-up adaptability to environmental conditions .\n\nthird , there is no conclusive test that the Earth has ever visited the envoys of other worlds.\n\nFourth, the page signals from foreigner civilizations accommodate not been flourishing . Did not show any signs of extraterrestrial activity , which seems fantastic , if we assume that these civilizations were able to achieve high levels of development , compared to Earth .\n\nSo extraterrestrials still are among the conjectural objects to be searched is of immense interest . current debate about the reality of extraterrestrial life , but only still observation and experimentation will issue whether there someplace inhabited worlds or we are unaccompanied , at least within our galaxy .
