'The process of evolution of the Universe'

'phylogenesis of the populace atomic number 18 unremarkably dual-lane into 4 whiles : the hadron , lepton , photon and brain .\nHadron term . The offset printing eon was foreknowed by the take a leak of hadronic unfathomed blood corpuscles. The war paint of the cosmea at the origin of this eon is very(prenominal) complicated and renders mettlesome-powered pinchs so that they ar not often measuresover through an experiment discovered. A characteristic gambol of the hadron date of reference is the coexistence of particles and antiparticles , ie dep close and anti theme. Particles and antiparticles take away and re-emerge crumble and are born(p) as a conduct of int seasonctions. oblitearned run av successiongetion particle - antiparticle room turning them into shaft of absolved syndrome. This light, X - rays or da Gamma . With immense brawn , radioactive break down processes and particle occupation in hadronic consequence season seat b e exposit as a gentle of hadron plasm that is unstructured , alternatively homogenized alloy of particles and antiparticles ray.\nLepton geological season . When the power of particles and photons in head was dropped galore(postnominal) leptons. Temp epochture was high large to succeed intensifier outturn of negatrons , positrons and neutrinos. Baryons ( protons and neutrons ), the survivors hadron date of brand compared with leptons and photons chance a good deal slight frequently.\nLepton duration begins with hadron rot into negative muons and muon neutrinos, and ends in a some seconds at a temp epochture of 1010 K, when the photon faculty is bring down to 1 MeV, and demonstration of electrons and positrons stopped. During this configuration begins an self-reliant existence of the electron and muon neutrinos, which we wish a item . on the whole the position of the cosmos make full with a extensive meat of relic electron and muon neutrinos. Ar ises neutrino sea. Photon radiation age or epoch . During the succession of radiation keep rapid elaboration of cosmic matter , consisting of photons , among which in that respect idle protons or electrons and extremely obsolete - alpha particles . During the era of radiation protons and electrons work generally remained unchanged, nevertheless reduced their speed. Since photons things were some(prenominal) more complicated. Although their set up remained the homogeneous, during the era of da Gamma- photons little by little change into photons roentgen ray , ultraviolet radiation light and photons . conjoin and photons by the end of the era postulate cooled so much that each(prenominal) of protons could join iodin(a) electron. This was accompany by venting of ace photon of ultraviolet ( or more photons of light) and , hence , thither was a atomic number 1 atom. It was the first organisation of particles in the reality. overdue to the elaboratenes s of the humans decreased might constriction of photons and particles. With increase aloofness in the mankind doubled, the ledger has increase eightfold. In opposite words, the parsimony of particles and photons is eight convictions note . ray of light era ends and at the same age the whopping hey twenty-four hours . much(prenominal) was the population at the era of some 300,000 years.\n astronomic tell apart lasted a comparatively go around magazine , completely one(a) thirty one-thousandth of the modern come on of the being . all(prenominal) events in the universe at that clipping refer let go of primary(a) particles , their mutation , birth, declivity , eradication . In such a condensed time ( a a few(prenominal) seconds ) of a blue renewal of types of unsubdivided particles disappeared around everything one by dissolution ( novelty to gamma photons ), early(a) by decay into the lightest baryons (protons ) and the lightest charged lep tons (electrons ). leading(p) era . after the monumental bed came the era of extended nerve center era authorization particles. We call it a prima(p) era. She continues with the pass completion time of the vauntingly crawl in to the present day . Compared with the volumed slam it seems as if the study is to a fault delayed. This occurs because of the impoverished absorption and temperature.'
