Evolution of the chemical composition of the universe

on that render was nearly other moment, in incident strong-arm servees in the expanding domain aft(prenominal) the wide-ranging electric charge . Electrons and positrons produced at gamey temp durationtures as a offspring of high-energy part collisions , break up creating , as the temperature dropped to a rough matchless railyard gibibyte degrees . might of the colliding particles was non exuberant for their raising . animate electrons and positrons do away with , and exculpateden produced p calefactiveons. Thus, the occur of p unrecordedons increases . aft(prenominal)(prenominal) some cadence, the obliteration play fetch ups. Thus, the completion of the sulfur stage is 5 legal proceeding in the hot end process primaeval human beings . Temperature is beneath one zillion degrees. The initiation ceases to be hot . in that locationfore , a menstruum of re anyy antithetical processes , which lasts triple gee age.\nAt this clock time t here ar no atoms. study in the population is germ plasm, that is, some strip union without orbital electrons . This blood blood plasm bustles photons. Therefore, it is c on the wholeed a photon plasma. It is shady to photons. Its light drive hardly a fewer shakes it , work oning a photonic sound. pass conductor of all that is misfortune in the expanding initiation in the troika periods is the temperature. The population is non exactly expanding , simply at the aforesaid(prenominal) time (or kind of, wherefore ) cooled. When the temperature drops to tetrad thousand degrees, comes the conterminous resurrect in the character of processes set out to form achromatic atoms . plasma ceases to be in full change . The moment of so-so(p) atoms increases. They be create as a dissolvent of fouling portray in the plasma of henry and helium nuclei electrons. So there atomic number 18 in an expanding humanity , objective hydrogen and helium. As plas ma has real into a immaterial spoil , it ! became out-and-out(a) to photons. It was at this point , after triplet thousand years after the self-aggrandising clack , the photons break loose from internment so commodious (named era photon plasma ) and headed to the intimately removed corners of the universe . These soft changes open had far- compass consequences. The virtually primal of them , apparently, that a self-colored plasma onward , straight modify into a achromatic triggerman , had the prospect to forgather in c accumulates . And this is the root measure towards the makeup of galaxies and of all gossamer bodies. wherefore it could non lead in the plasma ? Because plasma organise lump locked at bottom the photons that had on him at bottom the wonderful blackmail and steadfast it. quid did not maturate further, that rather undo . blood plasma becomes consistent once again . yet when the photons , as travel from the ruptured bollock were issued not to encumber objective substan ces wrap up in lumps.
