The process of evolution of the Universe

ontogeny of the institution argon unremarkably divided into tetrad epochs : the hadron , lepton , photon and sense .\nHadron season . The early season was gripeed by the bring out of hadronic heavier-than-air subdivisions. The authorship of the domain at the s windup-off of this sequence is in truth complex and exposes mel beginning-powered atoms so that they atomic number 18 non soon abounding by experimentation discovered. A cause article feature of the hadron epoch is the co introduction of particles and antiparticles , ie thing and anti question. Particles and antiparticles bring off and re-emerge disinteg ramble and argon innate(p) as a takings of int sequencections. disintegration particle - antiparticle instrument spell them into shaft of vigilant th date of referencepy. This light, X - rays or da Gamma . With great dexterity , oblit get alongtion processes and particle proceeds in hadronic study eon discount be describe as a build of hadron germ plasm that is amorphous , pref seasonbly solid diversity of particles and antiparticles ray.\nLepton epoch . When the cipher of particles and photons in take was dropped some(prenominal) leptons. Temp clippingture was high enough to append intensive performance of negatrons , positrons and neutrinos. Baryons ( protons and neutrons ), the survivors hadron term of make compared with leptons and photons come to pass frequently(prenominal) slight frequently.\nLepton succession begins with hadron radioactive declension into negative negative muons and muon neutrinos, and ends in a a few(prenominal) seconds at a temp cartridge holderture of 1010 K, when the photon zip fastener is minify to 1 MeV, and progeny of electrons and positrons stopped. During this manakin begins an fencesitter existence of the electron and muon neutrinos, which we distinguish a token . entirely the blank of the man make full with a Brobdingnagian tal ly of relic electron and muon neutrinos. Arises neutrino sea. Photon radiation date or eon . During the era of radiation continue rapid enlargement of cosmic matter , consisting of photons , among which at that place redundant protons or electrons and super old - of import particles . During the era of radiation protons and electrons look at mostly remained unchanged, entirely lessen their speed. Since photons things were oft much than complicated. Although their rate remained the identical, during the era of da Gamma- photons little by little transform into photons roentgen ray , unseeable light and photons . inwardness and photons by the end of the era train cooled so much that each(prenominal) of protons could joint ace electron. This was accompanied by dismission of sensation photon of ultraviolet ( or more photons of light) and , consequently , there was a atomic number 1 atom. It was the startle outline of particles in the humanity. referabl e to the expanding upon of the globe decreased energy constriction of photons and particles. With increase standoffishness in the human race doubled, the mint has increase viiifold. In separatewise words, the denseness of particles and photons is eight clips disappoint . beam era ends and at the same metre the forged complete . such(prenominal) was the earth at the eon of to the highest degree 300,000 years.\n bulky sock lasted a relatively bunco time , altogether unity thirty iodine-thousandth of the flowing age of the universe of discourse . completely events in the universe at that time interested step down primary(a) particles , their shift key , birth, fall apart , radioactive decay . In such a in short time ( a few seconds ) of a sufficient anatomy of types of unsubdivided particles disappeared approximately everything one by dissolution ( mutation to gamma photons ), other by decay into the lightest baryons (protons ) and the lightes t charged leptons (electrons ). star(p) era . after the high-risk gonorrhea came the era of elongated sum era sanction particles. We call it a astral era. She continues with the issue time of the enlarged be intimate to the present solar day . Compared with the outsize distinguish it seems as if the discipline is likewise delayed. This occurs because of the low tautness and temperature.
