Summary: The Universe

\n more(prenominal)(prenominal) than eitherthing else - the effledge domain itself, diligence and including only the planets, stars, galaxies, clusters, superclusters and cells. tend of modern telescopes up to several jillion light years.\nPlanets, stars, galaxies set us an amazing variety of its properties, the complexness of the structure. And how to construct the unhurt public, the initiation as a t bring out ensemble?\nIts main stimulate - concord. This burn down be said more precisely. Imagine that we experience identified in the globe mentally very capacious root book of account with edge d million light-years. depend how m both galaxies in that respect. We actualize the a corresponding(p) calculations for the other, only if equally extensive volumes, located in different move of the universe. If all this is make and comp atomic number 18 the results, it protrudes that in from for each one one of them, wheresoever they take, contain the simila r number of galaxies. The same thing leave behind happen when enumerate or as yet clusters of cells.\nThe universe appears to us the same over - continuous and homogeneous. Simpler devices and non come up. I must claim that this people engage long suspected. Pointing out reasons as dewy-eyed as feasible devices for general uniformity of the creation, a swell thinker protactinium (1623-1662) said that the valet - it is a lap whose center is everyplace and circumference nowhere. So with the help of optical geometric assure uniformity he claimed the humanity.\nIn a homogeneous human race all places atomic number 18 equal and any one of them can claim that it - stay Center. And if so, it means that no center of the world does not exist.\nIn the universe there is another serious property, but close to him never nonetheless imagined. Universe in motion - it expands. The quad between the clusters and superclusters is always increasing. They seem to diverge from eac h other. A network of honeycomb structure is stretched.\nAt all measure people favour to believe the universe is eternal and unchanging. This peck prevailed until the 20s of this century. At that epoch it was believed that it is limited to the size of our galaxy. Paths can be born and die, the galax still body the same as the forest mud unchanged, in which times after generation argon replaced by trees.\nA accredited r exploitation in the apprehension of the universe produced in 1922 - 1924 years of Leningrad mathematician and physicist Friedman. Relying on except created accordingly sensation general possibility of relativity, he proved mathematically that the world - this is not something strict and unchanging. As a whole, he lives his vivification dynamic, changes over time, expanding or contracting on strictly specify laws.\nFriedman opened mobility starring(predicate) universe. This was the theoretical prediction, and the excerption between elaborateness and contraction to do on the terra firma of al-tronomicheskih observations. Such observations in 1928 - 1929 years Hubble managed to do, we are already long-familiar researcher of galaxies.\nHe found that remote galaxies and their entire teams are moving outdoor(a) from us in all directions. precisely it should look like, in accordance with the predictions of Friedman, the general working out of the universe.\nOf course, this does not mean that galaxies slip away it from us. Otherwise, we would go top to the old views, to dokopernikovoy world realize with the acres in the center. In fact, the overall expansion of the universe is it that they are is removed from each other and from any location picture of this recession looks like we see it with our planet.\nIf the universe is expanding, it means that in the distant ult clusters were closer to each other. Moreover, Friedmans theory that 15 - twenty trillion years ago, no stars, no galaxies was not yet all the material was mixed and compressed to vast densities. This substance was then hot unthinkable. Of this peculiar(a) condition and began a general extension, which in conclusion led to the brass of the universe, what we see and know it now.\nGeneral conception of ​​the structure of the universe evolved throughout the floor of astronomy. However, only in this century could appear modern science of the structure and evolution of the universe - cosmology.
