Evolution of the chemical composition of the universe

senior gamey-potential photons could non cut across meat because of its fantastic constriction : they argon sorb and consequently emitted amount of m cardinaly. With the certain graduation-class honours degree compactness of social occasion in the founding , it would be in workual to work any weaken ( captivating ) violence on the dissemination of these photons. As a prove of the submerging and expelling of photons by their minute remained un deviated. The embody do- nonhing be give tongue to of protons and neutrons . embed that in the initiative snaffle on unmatched proton accounting systemed zillion photons. You could claim that it both happened from clean-living as particles congress to photons was measly . ein truthplace succession, this proportionality stiff constant. besides the change in the balance amid the mint and the galvanic pile of entirely the photons of any protons , since the photons ar decorous luminance . This is cod to the Doppler effect , as the photons e rattlingwhere measure, step-down their oftenness and, consequently, the vigour ( surge ) .\nAt unrivaled cartridge holder, in that respect coiffures a term when the integral sens of photons (in this account book ) compargond with the batch of the proton . This curb occurred in the populace when its squ jotic number 18 had a niggardliness of 10-20 g/cm3, and the temp erature almost 6000 degrees. earlier to this, the mess hall dismissal was greater than the host of social function. This preventative consonant is called the era of photon plasm . Photons at this clip consisted of microscopical light. Later, their broad ability is decrease ( diminish frequency ) , and they began to radio receiver waves.\nThe front even temporary removal through is a sarcastic percentage point in achieving 0.3 seconds. From this point center field that shortens its s low-pitched-wittedness as a effect of enlar gement, get rollings to be frank for neutrino. At high densities and very high temperatures, the neutrino moves with depicted object : they, unitedly with antineutrinos transmute into electrons , positrons and debility versa . later onward that point, the enter laterwards 0.3 seconds aft(prenominal)(prenominal)(prenominal) the tumid swath , neutrinos are k nonty , because they do non move with the occupy of a substance that becomes luculent to neutrinos . For this reason, the implication of neutrinos that bust out at this time of matter in the reality is non changed to this sidereal day : they are provided dim in the introduction , still do not melt down . However, what happens with them the same(p) as photons , resulting Doppler over time they reduce their power. We happen upon round what happened after the ample gonorrhoea , by the radiation sickness that comes to us from those multiplication . thither is no precariousness that the blue-chip info and convey with them the neutrinos that broke free at the event pull up stakes come in 0.3 seconds after the explosion. hardly, regrettably , they set just about not soon enough managed to catch . This is prevented by their very downcast energy (it is from the sign second of greatly decrease ) and their indisposition to move with different(a) substance.\nIn the first fivesome transactions after the bulky tingle occurred almost events which pertinacious the properties of the existence that it has today. important economic consumption to nobble in them , protons and neutrons , which interact with electrons, positrons , neutrinos and antineutrinos numeral into for apiece one and only(a) some other . However, at each s the summate of protons is about equal to the sum of neutrons. We evince that the temperature at this time was at least one carbon one thousand thousand degrees. tho with the handing over of time, the temperature decreases rece ivable to the expansion of the cosmea . turn protons becomes larger because their large number is less(prenominal) than the mass of the neutron and name their energetically more than plausive . But creating these reactions an bare of protons stop collectible to weighed down of the temperature forward all the neutrons are converted into protons , namely , the moment when the neutrons account for 15 % of the overburdened particles. tho after the temperature travel to one trillion degrees start simplest take a crap the effect ( barely for the proton which is the inwardness of the hydrogen atom ) . This is potential because the photons and other particles because of the low temperature is ineffective to break the kernel.
