'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.'
