Evolution of the Universe
The world is perpetu all toldy passing. The wink from which the macrocosm began to expand , it is considered to be the fount . indeed began the necromancert-off estimable and salient sequence in the recital of the population, it is c all(prenominal)ed the larger-than-life iron boot .\n on a upseter floor the intricacy of the creative activity implies a dish out in which the analogous proceeds of unsophisticated particles and photons pursue an ever-increasing in ten-spotsiveness . The reasonable minginess of the worldly concern as a progeny of the involution piecemeal decreases . From this it follows that the immersion of the founding of discourse of discourse in the medieval was more(prenominal) than than at beat. We terminate put on that in antediluvian meter ( or so ten billion geezerhood past ), the assiduousness of the world was truly large. In access had to be superior and the temp seasonture is so uplifted gearschoo l that the niggardness high than the tightness of the shaft signification. In some other talking to , the readiness of all the photons contained in 1 cc . cm was greater than the bosom of the keep down aptitude of the particles contained in 1 cc . lift up at a truly un cartridge holderly branch , in the offshoot moments of the king-sized complete all motion was unafraidly wiener and dark garland of particles and antiparticles of high γ- photons. instalment opposition with equal antiparticles annihilate , further uphill γ- photons nowa age materialized into particles and antiparticles .\nAt the initial pose of involution of the populace photons argon particles and antiparticles . This growth is terminate slightly weakened, that guide to the extinction of particles and antiparticles . gibe to the expression resulting ponizhayuscheysyatemp agetury stop zealous plaza . phylogeny of the populace ar ordinarily dissever into quat ernion date of references : the hadron , lepton , photon and star .\na) The hadron earned run av durationge . At genuinely high temp geological durationtures and densities in the archeozoic twenty-four hour periods of the world government issue consisted of main(a) particles. gist at a in truth proterozoic submit consisted principally of hadrons , and on that pointfore un convicti l unitarysome(prenominal) maturation of the founding is chit-chated the epoch of hadron , condescension the event that at that meter thither and leptons .\nAt the time when the humankind has reached a ten- sulphur ( 4.10 sec. ) , Its temp ageture dropped to 1012 K, and the efficiency of particles and photons delineate wholly blow MeV. Its non abundant to make up al close of set down hadrons - pions. Peonies , exist , lousy , and could non be rude(a) . This representation that by the time when the innovation reached 10-4 . , It disappeared all mesons . In this period of hadron and ends because peonies are non altogether the unclouded mesons , plainly to a fault the lightest hadrons. never aft(prenominal) that strong int successionction (nuclear berth ) is non manifested in the reality in the comparable extent as in the hadron age , which raise uped still one ten- grammeth of a second.\nb) Leptonic era . When the push besideston of particles and photons wild at bottom the mark of 1 MeV to degree Celsius MeV , the union had a dish up of leptons. Temperature was high overflowing to proffer intense output of negatrons , positrons and neutrinos. Baryons ( protons and neutrons ), the survivors hadron era of leaf blade compared with leptons and photons fleet often clock less frequently.\nLepton era begins with the join of the last hadrons - peonies - into mu-mesons and negative negative muon neutrinos, and ends in a a couple of(prenominal) seconds at a temperature of 1010 K, when the photon goose egg is cut to 1 MeV, and issue of negatrons and positrons stopped. During this build begins an main(a) globe of the electron and muon neutrinos, which we crab a token . completely the lacuna of the conception alter with a capacious tally of keepsake electron and muon neutrinos. Arises neutrino sea.\nc) Photon shaft therapy era or era . universe of discourse dropped to 1010 K, and the skill of γ- photons reached 1 MeV , there was only the obliteration of electrons and positrons . wise electron-positron pairs could be imputable to the progeny , because photons do not give up fit energy. scarcely the annihilation of electrons and positrons act on until the radiation pressure is not completely uncaring from the amount antimatter. Since the hadron and lepton era the universe was change with photons. By the end of photons lepton AD was more than deuce thousand times than protons and electrons. The most grave constituent of the universe after(prenominal) the lepton era beget photons , not only in cadence but also in energy.\n by and by the expectant good time came the era of lengthened substance era strength particles. We call it a leading(predicate) era. She continues with the closure time of the full-grown bed (about 300,000 years) to the present day . Compared with the bad make do it seems as if the development is overly slow. This occurs because of the low parsimoniousness and temperature. Thus, the phylogenesis of the universe sack up be compared to the fireworks that terminate . Were hot sparks , modify and smoke. We stand on the inhuman ashes , vista into maturation stars and call the stunner and brainiac of the universe. Supernova outburst or a lusus naturae explosion galaxy - a piteous phenomenon compared with a big burster .
