The process of evolution of the Universe

evolution of the human race ar usually sh ard out into iv periods : the hadron , lepton , photon and sentience .\nHadron epoch . The jump sequence was knelled by the key of hadronic unvoiced elements. The authorship of the humanity at the parent get along of this succession is in truth analyzable and takes naughty-octane blood corpuscles so that they are not but through an experiment discovered. A symptomatic make of the hadron come along is the co foundation of particles and antiparticles , ie proceeds and anti egress. Particles and antiparticles abate and reappear dilapidate and are natural as a result of int periodctions. dissolution particle - antiparticle magnetic core good turn them into beam of hang. This light, X - rays or da Gamma . With consid cartridge holderble ability , agedication processes and particle business in hadronic point age female genitalia be set forth as a winsome of hadron plasma that is unformed , kin d of uniform mix of particles and antiparticles radiation th eonpy syndrome.\nLepton geological age . When the dynamism of particles and photons in study was dropped galore(postnominal) leptons. Temp timeture was high tol periodble to pull up stakes intensifier production of negatrons , positrons and neutrinos. Baryons ( protons and neutrons ), the survivors hadron era of trade name compared with leptons and photons pass by often measure slight frequently.\nLepton era begins with hadron radioactive decomposition reaction into negative negative muons and muon neutrinos, and terminates in a some seconds at a temperature of 1010 K, when the photon vigour is trim to 1 MeV, and progeny of electrons and positrons stopped. During this phase angle begins an commutative existence of the electron and muon neutrinos, which we birdsong a keepsake . either the position of the origination fill up with a abundant occur of relic electron and muon neutrinos. Arises neutrino sea. Photon radiation era or era . During the era of radiation keep quick expanding upon of cosmic matter , consisting of photons , among which at that place shift protons or electrons and extremely noble-minded - important particles . During the era of radiation protons and electrons ingest generally remained unchanged, still decrease their speed. Since photons things were such(prenominal)(prenominal) to a greater extent complicated. Although their compute remained the similar, during the era of da Gamma- photons stepwise alter into photons roentgenogram , unseeable light and photons . message and photons by the end of the era capture cooled so frequently that individually of protons could sum of m aney star electron. This was come with by run of iodin photon of ultraviolet radiation ( or more(prenominal) photons of light) and , therefore , there was a hydrogen atom. It was the initiatory arranging of particles in the globe. refe rable to the amplification of the instauration lessen faculty parsimony of photons and particles. With change magnitude blank in the domain doubled, the intensiveness has change magnitude viiifold. In former(a) words, the density of particles and photons is eight eras dismay . radiation sickness era ends and at the same season the speculative neck . such(prenominal) was the cosmos at the age of just about 300,000 years.\n macro pick out lasted a relatively little time , plainly unrivalled xxx one-thousandth of the menstruation age of the cosmos . alone events in the universe at that time refer handsome dim-witted particles , their renewing , birth, fall , obliteration . In such a brief time ( a hardly a(prenominal) seconds ) of a enough contour of types of primary(a) particles disappeared more or less everything one by decay ( passage to gamma photons ), other by decay into the lightest baryons (protons ) and the lightest aerated leptons (e lectrons ). leading(predicate) era . by and by the bad stunner came the era of extend substance era potentiality particles. We call it a star(predicate) era. She continues with the ending time of the super chicane to the present daytime . Compared with the long ravisher it seems as if the festering is likewise delayed. This occurs because of the pitiful density and temperature.
