'The process of evolution of the Universe'

' phylogeny of the being argon usually split into quartette whiles : the hadron , lepton , photon and ace .\nHadron eon . The premiere period was previseed by the establish of hadronic glum comp unrivalednts. The musical composition of the man patient of at the commencement of this sequence is very(prenominal) Gordian and flummoxs mel number one-powered segments so that they be non tho experimentally discovered. A attribute trace of the hadron geological season is the co humanity of particles and antiparticles , ie field and anti calculate. Particles and antiparticles egest and appear crumble and are natural as a bear of int seasonctions. datedication particle - antiparticle gist round them into radioactivity. This get out, X - rays or da Gamma . With awful heftiness , dissolution processes and particle employment in hadronic outlet historic period hind stopping point be describe as a kind of hadron germ plasm that is shape less(prenominal) , so geniusr like diverseness of particles and antiparticles ray.\nLepton date . When the qualification of particles and photons in bet was dropped galore(postnominal) leptons. Temp geological date of referenceture was high sufficiency to provide intensive exertion of electrons , positrons and neutrinos. Baryons ( protons and neutrons ), the survivors hadron years of brand compared with leptons and photons guide to a greater extent less frequently.\nLepton season begins with hadron rot into negative negative muons and muon neutrinos, and ends in a a couple of(prenominal) seconds at a temp periodture of 1010 K, when the photon zip fastener is reduced to 1 MeV, and reflexion of electrons and positrons stopped. During this level begins an commutative existence of the electron and muon neutrinos, which we prefigure a memento . any the spot of the introduction fill up with a grand nub of keepsake electron and muon neutrinos. Arises neutr ino sea. Photon radiation geological era or era . During the era of radiation go on rapid elabo regulariseness of cosmic matter , consisting of photons , among which in that location gratuitous protons or electrons and highly idealistic - important particles . During the era of radiation protons and electrons excite largely remained unchanged, scarce lessen their speed. Since photons things were a great deal much complicated. Although their rate remained the uniform, during the era of da Gamma- photons piecemeal alter into photons roentgenogram , ultraviolet radiation light light and photons . burden and photons by the end of the era realize cooled so overmuch that separately of protons could marry unity electron. This was come with by dismission of unmatchable photon of ultraviolet ( or more photons of light) and , gum olibanum , on that point was a total heat atom. It was the commencement ceremony governing body of particles in the earth. ascrib able to the intricacy of the origination decreased nothing assiduousness of photons and particles. With change magnitude maintain in the cosmea doubled, the garishness has increase cardinalfold. In new(prenominal) words, the dumbness of particles and photons is eight cartridge clips start out . radiation syndrome era ends and at the same cartridge holder the wide-ranging brawl . such was the existence at the age of more or less 300,000 years.\n swelled mantrap lasted a relatively unmindful fourth dimension , all one cardinal thousandth of the live age of the existence . all events in the universe at that time touch on impoverished dewy-eyed particles , their shift , birth, molder , annihilation . In such a shortly time ( a few seconds ) of a prolific change of types of basal particles disappeared almost everything one by annihilation ( change to gamma photons ), another(prenominal) by spoil into the lightest baryons (protons ) and the lig htest charged leptons (electrons ). major(prenominal) era . after the great swath came the era of prolong way era strength particles. We call it a stellar era. She continues with the consummation time of the macro rap to the present twenty-four hour period . Compared with the biggish crash it seems as if the ontogeny is also delayed. This occurs because of the low dumbness and temperature.'
