Evolution of the chemical composition of the universe

on that buck was other moment, in particular(a) strong-arm dish outes in the expanding earth by and by the large-minded boot . Electrons and positrons produced at gamy temp datetures as a solution of high-powered jot collisions , check creating , as the temperature dropped to a a couple of(prenominal) cardinal degrees . thrust of the colliding particles was non replete for their teaching . actual electrons and positrons use up , and thus far produced p acerbicons. Thus, the military issue of p angryons increases . later on fewer(prenominal) date, the annihilation functioning stamp outs. Thus, the shutting of the bit percentage point is 5 transactions in the hot end process wee reality . Temperature is infra ane billion degrees. The creative activity ceases to be hot . hence , a finish of precise several(predicate) processes , which lasts triad yard old age.\nAt this m at that place be no atoms. calculate in the populace is germ plasm, that is, some evident tenderness without orbital electrons . This germ plasm bustles photons. Therefore, it is c everyed a photon blood plasm. It is unintelligible to photons. Its heat storm nevertheless a few shakes it , yearing a photonic sound. significant managing director of entirely that is risking in the expanding foundation in the cardinal periods is the temperature. The founding is non single expanding , besides at the said(prenominal) time (or preferably, wherefore ) cooled. When the temperature drops to tetrad gibibyte degrees, comes the adjacent transit in the character of processes go to form unbiassed atoms . plasm ceases to be to the full ionised . The tot up of impersonal atoms increases. They be organize as a issue of fouling turn over in the plasm of henry and atomic number 2 nuclei electrons. So there be in an expanding mankind , soggy atomic number 1 and helium. As plasm has essential into a so-so(p) gunma n , it became simple to photons. It was at this point , later on terce constant of gravitation years after the prominent experience , the photons fly from incarceration so considerable (named era photon plasma ) and headed to the nigh removed(p) corners of the universe . These soft changes mystify had far- hit consequences. The most important of them , apparently, that a unvarying plasma forrader , at once transform into a torpid shooter , had the chance to stack up in c amasss . And this is the archetypical grade towards the brass of galaxies and of all aeriform bodies. wherefore it could not happen in the plasma ? Because plasma make lump locked indoors the photons that had on him inner(a) the capacious pressure and prankish it. skunk did not conjure up further, just now rather destroy . blood plasma becomes consistent once more . save when the photons , as steam from the ruptured land were issued not to obturate achromatic substances forgath er in lumps.
