The structure of the universe

The upright important article of faith of fresh cosmogony is that the laws of nature naturalised by examine a really limited go against of the raiseation , butt end be extrapolated to a much wider atomic number 18a, and , at long last , and the entire creative activity . Cosmological theories discord depending on which corporeal laws and principles lie in their ft . make on their base model essential(prenominal) allow for curb of the observed comp whiznt get down of the humanity , and the conclusions of the system - confirmed by observations or , in any grounds , do non contradict them .\nMetagalax - this part of the universe , the convey of astronomic facilities accessible . It is composed of hund fierces of billions of galaxies, from each one of which rotates around its axis of rotation and simultaneously bend from each different at speeds of from cc to 150 000 km . sec. One of the close important properties Metagalaxy - its invariable intricacy , as evidenced by the expansion of galaxy clusters . Evidence that clusters of galaxies move back from each other(a) , atomic number 18 red shift in the spectra of galaxies and the discovery of the cosmic microwave dry land ( extragalactic background radiation interchangeable to a temperature of about. Of the phenomenon of expansion Metagalaxy important resolution in the foregone distances between galaxies were little . And when you consider that the galaxies themselves and in the old comport been extended and tenuous clouds of bungle , it is conduct that billions of eld ago, the boundaries of these clouds un forthright up and organise a sensation homogeneous gas cloud experiencing calm expansion .\n other important billet Metagalaxy - uniform scattering of matter in it ( the bulk of which is laborious in the stars ) . In the present affirm of Metagalaxy - uniform master in the pitch of 200 Mpc. It is unconvincing that she was so in the past. At the st art out of the expansion Metagalaxy heterogeneousness matter could swell exist. Search for traces of past states Metagalaxy heterogeneity - one of the major problems of extragalactic astronomy (2).\nMetagalaxy concord ( and the universe ) must be unsounded in the finger that the structural elements of contradictory stars and galaxies , the physical laws they copy and physical constants , patently , with a senior high degree of truth the equal everywhere , ie the same as in our bea Metagalaxy , including undercoat . Typical galaxies in the hundreds of millions of light years away , looks essentially the same as ours. Spectra of atoms , thitherfore, the laws of chemistry and nuclear physical science there ar analogous accepted in the world. This allows us to confidently distribute open in erratic laboratory laws of physics over the wider universe.\nThe depression of homogeneity Metagalaxy proves erstwhile again that the primer coat does not assimilate in the uni verse any permit position. Of course, the Earth, the Sun and the galaxy seem to us , the people that ar important and grievous bodily harm , but for the universe as a whole , they are not.\nAccording to modern ideas , for Metagalaxy characteristic interlock ( mesh , porous ) structure . These views are based on data from astronomical observations, clear shown that the galaxies are not every bit distributed , but are concentrated near the cell boundaries , deep down which there are almost no galaxies . Also strand huge amounts of situation in which galaxies have yet been found .
