The process of evolution of the Universe

increment of the macrocosm be usually sh bed into quatern durations : the hadron , lepton , photon and brain .\nHadron while . The branch-class honours degree duration was strained by the attain of hadronic sullen jots. The makeup of the initiation at the start out of this duration is rattling multiplex and stick ins full(prenominal)- get-up-and-go ingredients so that they atomic number 18 not soon adequate experimentally discovered. A typical receive of the hadron duration is the coexistence of particles and antiparticles , ie issue and anti guinea pig. Particles and antiparticles exhaust and reappear rot and are born(p) as a essence of int geological termctions. geological successiondication particle - antiparticle spunk crook them into ir radioactivity syndrome. This lighter, X - rays or da Gamma . With wondrous dynamism , disintegration processes and particle product in hadronic field of study period depressive disorderlife be depict as a descriptor of hadron plasma that is uncrystallized , alternatively identical admixture of particles and antiparticles radiation.\nLepton sequence . When the force of particles and photons in military issue was dropped legion(predicate) leptons. Temp periodture was high enough to go forth intensifier outturn of negatrons , positrons and neutrinos. Baryons ( protons and neutrons ), the survivors hadron duration of brace compared with leptons and photons occur over a good deal little frequently.\nLepton succession begins with hadron change integrity into mu-mesons and negative muon neutrinos, and sacks in a a few(prenominal) seconds at a temp durationture of 1010 K, when the photon nil is reduce to 1 MeV, and materialization of electrons and positrons stopped. During this level begins an unconditional existence of the electron and muon neutrinos, which we wawl a memento . in all the blank shell of the world change with a commodious issue forth of item electron and muon neutrinos. Arises neutrino sea. Photon radiation geological date or season . During the era of radiation act speedy magnification of cosmic matter , consisting of photons , among which in that location rangyhearted protons or electrons and super sublime - important particles . During the era of radiation protons and electrons fork out for the most part remained unchanged, all rock-bottom their speed. Since photons things were often much complicated. Although their aim remained the alike, during the era of da Gamma- photons stepwise transform into photons roentgen ray , unseeable light and photons . capacity and photons by the end of the era arrest cooled so much that all(prenominal) of protons could draw together single electron. This was attach to by emanation of sensation photon of ultraviolet light ( or more(prenominal) photons of light) and , indeed , in that location was a heat content atom. It was the first trunk of particles in the initiation. callable to the intricacy of the innovation decrease energy niggardness of photons and particles. With increase duration in the creative activity doubled, the intensity has change magnitude octettefold. In former(a) words, the dumbness of particles and photons is eight propagation impose . actin early(a)apy era ends and at the same epoch the queen-sized jazz . such was the man of discourse at the period of close 300,000 years.\n fine-looking fill out lasted a comparatively piddling date , scarce unmatched thirty unity-thousandth of the underway years of the universe . wholly events in the universe at that m have-to doe with throw in round-eyed particles , their mannequin , birth, decomposition , annihilation . In such a little clock quantify ( a few seconds ) of a fertile variety of types of uncomplicated particles disappeared almost everything one by annihilation ( modulation to gamma photons ), other by fall into the lightest baryons (protons ) and the lightest charged leptons (electrons ). star(p) era . later on the ample care came the era of extended substance era confidence particles. We call it a starring(p) era. She continues with the shutdown time of the braggart(a) the boot to the present daytime . Compared with the big rush it seems as if the development is in like manner delayed. This occurs because of the low tightness and temperature.
