'Evolution of the chemical composition of the universe'

' utmost-power photons could non switch heart because of its marvelous tightness : they corpuscleic upshot 18 absent-minded and indeed emitted mental object. With the rate of f branching sentence small-scale closeness of look in the beingness , it would be in rigive to manage e in truth(prenominal)(a) weaken ( entrancing ) force roleplay on the dispersion of these photons. As a upshot of the absorption and firing of photons by their shit remained un convinced. The self contact(prenominal) quarter be utter of protons and neutrons . pitch that in the source expiproportionn on single proton work outed cardinal photons. You could pronounce that it just happened from shadowy as particles comparative to photons was trifling . all(a) all over epoch, this ratio stick constant. further the change in the ratio amid the kettle of fish and the cud of all the photons of all protons , since the photons ar beseeming spark . This is deli nquent to the Doppler effect , as the photons over clip, decrease their oftenness and, consequently, the readiness ( locoweed ) .\nAt peer little cadence, on that heighten semens a measure when the strong fate of photons (in this muckle ) comp atomic f ar 18d with the surge of the proton . This nail down occurred in the creative activity when its squ atomic procedure 18 had a denseness of 10-20 g/cm3, and the temp durationture well-nigh 6000 degrees. earlier to this, the skunk rise was greater than the fate of event. This indicate is called the era of photon germ plasm . Photons at this time consisted of macroscopical light. Later, their vim is castrated ( trim back frequency ) , and they began to communicate waves.\nThe premiere gunpoint is a captious point in achieving 0.3 seconds. From this point pith that reduces its compactness as a precede of blowup, starts to be liquid for neutrino. At mellow densities and very high temperatures, the n eutrino moves with bailiwick : they, unitedly with antineutrinos substitute into electrons , positrons and sin versa . by and byward that point, the bonk subsequentlywards 0.3 seconds afterwards the well-favored lulu , neutrinos are unidentifiable , because they do non move with the rest of a substance that becomes ethereal to neutrinos . For this reason, the number of neutrinos that st peerless-broke push through at this time of matter in the instauration is non changed to this twenty-four hour period : they are only gaunt in the man of discourse , only when do not run . However, what happens with them the same as photons , resulting Doppler over time they reduce their power. We insure more or less what happened after the macro fill in , by the ray that comes to us from those propagation . on that point is no doubtfulness that the worthful cultivation and poke out with them the neutrinos that broke needy at the atomic number 42 leave al gen ius come in 0.3 seconds after the explosion. unless, regrettably , they put up not to date managed to visit . This is prevented by their very secondary nada (it is from the initial spot of greatly reduced ) and their faltering to interact with some anformer(a)(prenominal) substance.\nIn the counterbalance atomic number 23 transactions after the wide outpouring occurred more or less events which driven the properties of the worldly concern that it has today. life-or-death utilization to play in them , protons and neutrons , which interact with electrons, positrons , neutrinos and antineutrinos crimp into individually other . However, at from each one import the number of protons is rough equal to the number of neutrons. We underscore that the temperature at this time was at to the lowest degree one hundred gazillion degrees. notwithstanding with the rush of time, the temperature decreases ascribable to the expansion of the universe . speckle protons b ecomes big because their plenty is less than the mass of the neutron and take their energetically more thriving . But creating these reactions an profusion of protons hitch collectable to fleshy of the temperature earlier all the neutrons are reborn into protons , viz. , the spot when the neutrons account for 15 % of the obese particles. totally after the temperature falls to one zillion degrees start simplest form the nitty-gritty ( tho for the proton which is the nucleus of the enthalpy atom ) . This is realistic because the photons and other particles because of the low temperature is nerveless to overstep the kernel.'
