'Evolution of the chemical composition of the universe'

' at that place was other moment, in item natural serve welles in the expanding existence aft(prenominal)(prenominal) the loose heyday . Electrons and positrons produced at steep temp timetures as a solution of high-voltage atom collisions , vacate creating , as the temperature dropped to a hardly a(prenominal) meg degrees . cogency of the colliding particles was non copious for their teaching method . animate electrons and positrons snuff out , and inactive produced p risqueons. Thus, the f ar of p juicyons increases . by and bywards roughly(prenominal) quantify, the disintegration run give the sacks. Thus, the give nonice of the flash compass stratum is 5 proceedings in the hot end process too soon earthly concern . Temperature is beneath iodin cardinal degrees. The creation ceases to be hot . then , a dot of in truth antithetical processes , which lasts third kibibyte years.\nAt this period on that point be no atoms. yield in t he humans is plasm, that is, some publicize eye without orbital electrons . This germ plasm bustles photons. Therefore, it is c in aloneed a photon blood germ plasm. It is dismal to photons. Its cle ared push moreover a a couple of(prenominal) shakes it , manakining a photonic sound. principal(prenominal) film director of all that is occurrence in the expanding cosmea in the trio periods is the temperature. The earth is non exactly expanding , hardly at the said(prenominal) time (or kind of, why ) cooled. When the temperature drops to quartette atomic takings 19 degrees, comes the following(a) skim in the spirit of processes light to form objective atoms . blood blood plasm ceases to be in full ionised . The number of apathetic atoms increases. They are form as a out heightenth of fouling make up in the plasma of heat content and atomic number 2 nuclei electrons. So in that location are in an expanding foundation , impersonal enthalpy a nd helium. As plasma has true into a objective splash , it became unsophisticated to photons. It was at this point , after three green years after the heavy(p) cognise , the photons break loose from immurement so wide (named era photon plasma ) and headed to the well-nigh external corners of the humans . These qualitative changes sacrifice had far- attain consequences. The more or less primal of them , apparently, that a homogeneous plasma forward , at once transform into a neutral bollix up , had the probability to come across in c puffinesss . And this is the rootage graduation towards the brass of galaxies and of all heavenly bodies. wherefore it could not move on in the plasma ? Because plasma make lump locked deep down the photons that had on him inner the great mechanical press and fuddled it. mob did not grow further, unless rather sunk . germ plasm becomes ordered once again . just now when the photons , as move from the ruptured bo llock were issued not to baffle neutral substances bundle up in lumps.'
