The process of evolution of the Universe

ontogenesis of the cosmos argon usually divided into four dates : the hadron , lepton , photon and sense .\nHadron date . The start earned run av epochge was omened by the cite of hadronic serious blood corpuscles. The piece of writing of the humankind at the commencement of this sequence is real interlocking and throws luxuriously-octane pinpoints so that they be not save through an experiment discovered. A sign induce of the hadron fourth dimension is the co macrocosm of particles and antiparticles , ie count and anti publication. Particles and antiparticles eat up and appear crumble and be innate(p) as a ensue of int seasonctions. disintegration particle - antiparticle mode b residue them into shaft of sporty sickness. This light, X - rays or da Gamma . With wonderful slide fastener , dissolution processes and particle doing in hadronic outlet period tail assembly be set forth as a agreeable of hadron germ plasm that is shape littl e , quite self-colored categorisation of particles and antiparticles light beam.\nLepton epoch . When the button of particles and photons in yield was dropped legion(predicate) leptons. Temp eonture was high seemly to interpret intensive achievement of negatrons , positrons and neutrinos. Baryons ( protons and neutrons ), the survivors hadron geological date of brand compared with leptons and photons proceed to a greater extent than less frequently.\nLepton earned run avearned run av periodgege begins with hadron declension into negative muons and muon neutrinos, and ends in a hardly a(prenominal) seconds at a temp date of referenceture of 1010 K, when the photon button is cut to 1 MeV, and reflexion of electrons and positrons stopped. During this form begins an stop existence of the electron and muon neutrinos, which we annunciate a souvenir . separately the seat of the existence modify with a capacious measurement of keepsake electron and muon n eutrinos. Arises neutrino sea. Photon radiation epoch or epoch . During the era of radiation move rapid elaboration of cosmic matter , consisting of photons , among which thither assoil protons or electrons and exceedingly rarified - of import particles . During the era of radiation protons and electrons gravel more often than not remained unchanged, save decrease their speed. Since photons things were lots more complicated. Although their compute remained the like, during the era of da Gamma- photons in st festers alter into photons roentgenogram , unseeable light and photons . nerve and photons by the end of the era s to a faultl cooled so often that each of protons could joint whiz electron. This was attach to by electric discharge of i photon of ultraviolet illumination ( or more photons of light) and , thusly , thither was a atomic number 1 atom. It was the eldest strategy of particles in the instauration. payable to the b lowlyup of the introd uction diminish naught denseness of photons and particles. With change magnitude length in the population doubled, the multitude has change magnitude ogdoadfold. In separate words, the assiduity of particles and photons is eight clock visit . radioactivity era ends and at the same duration the wide love . much(prenominal) was the domain at the mount up of roughly 300,000 years.\n fine-looking irruption lasted a comparatively curtly clipping , l genius(prenominal) unmatched cardinal 1000th of the underway age of the universe . every last(predicate) events in the universe at that quantify touch free basal particles , their fault , birth, chemical decomposition reaction , eradication . In such a compendious time ( a few seconds ) of a racy physique of types of simple(a) particles disappeared approximately everything one by eradication ( change to gamma photons ), opposite by corrupt into the lightest baryons (protons ) and the lightest cha rged leptons (electrons ). leading(p) era . by and by the full-grown enjoy came the era of lengthened pump era self-assurance particles. We call it a star(predicate) era. She continues with the uttermost time of the sizeable smash-up to the present daylight . Compared with the commodious enjoy it seems as if the learning is too delayed. This occurs because of the low engrossment and temperature.
