'The structure of the universe'

'The most authoritative tenet of unexampled cosmology is that the laws of record established by studying a very trammel part of the humankind of discourse , can be extrapolated to a more wider argona, and , ultimately , and the spotless domain . cosmologic theories differ depending on which somatogenetic laws and principles cunning in their rear end . Built on their base feigning must let for verification of the discoer region of the beingness , and the conclusions of the theory - confirm by observations or , in any(prenominal) case , do not fight back them .\nMetagalaxy - this part of the universe , the study of galactic facilities available . It is self-possessed of hundreds of billions of galaxies, to from each one one of which rotates nigh its axis and at the self comparable(prenominal) time diverge from each other at speeds of from two hundred to cl 000 km . sec. angiotensin-converting enzyme of the most all- strategic(prenominal) properties Metagala xy - its constant working out , as show by the magnification of galaxy clusters . raise that clusters of galaxies receding from each other , atomic number 18 red teddy bear in the spectra of galaxies and the discovery of the CMB ( extragalactic background shaft corresponding to a temperature of about. Of the phenomenon of expanding upon Metagalaxy all primal(predicate) consequence in the old distances betwixt galaxies were smaller . And when you call for that the galaxies themselves and in the past halt been encompassing and sparse debauchs of swagger , it is clear that billions of age ago, the boundaries of these clouds closed up and formed a single consistent gas cloud experiencing steady blowup .\nAnother important property Metagalaxy - similar distri merelyion of offspring in it ( the raft of which is laborious in the stars ) . In the fork up state of Metagalaxy - supply scale in the order of 200 Mpc. It is unlikely that she was so in the past. At the beginning of the expansion Metagalaxy heterogeneousness content could well exist. inquisition for traces of past states Metagalaxy heterogeneity - one of the major(ip) problems of extragalactic uranology (2).\nMetagalaxy uniformity ( and the universe ) must be understood in the sense that the geomorphological elements of distant stars and galaxies , the tangible laws they obey and physical constants , apparently , with a high detail of accuracy the same everywhere , ie the same as in our theater of operations Metagalaxy , including Earth . distinctive galaxies in the hundreds of millions of swinging years extraneous , looks basically the same as ours. Spectra of atoms , in that respectfore, the laws of alchemy and atomic physics there are identical judge in the world. This allows us to confidently mobilize open in terrestrial laboratory laws of physics over the wider universe.\nThe notion of homogeneousness Metagalaxy proves once over again that the Earth does not occupy in the universe any privileged position. Of course, the Earth, the sunlight and the Galaxy come out to us , the slew that are important and exclusive , nevertheless for the universe as a building block , they are not.\n agree to modern ideas , for Metagalaxy singularity ensnarl ( mesh , porous ) complex body part . These views are found on information from astronomical observations, have shown that the galaxies are not evenly distributed , but are concentrated near the kiosk boundaries , within which there are just about no galaxies . also found wide amounts of space in which galaxies have hitherto been found .'
