Mhinduro dzeisotropic uye dzakaenzana dzeiyi equation dzakasimbiswa, mhinduro dzaFriedmannLemaîtreRobertsonWalker, dzinobvumira vezvemuviri kuti vagadzire chisiko chakapfuurira mumakore 14 mabhiriyoni apfuura kubva kunzvimbo inopisa, yapakuvamba yeBig Bang. Kamwe nhamba duku yemipimo somuenzaniso ukuru hwepakati hwezvinhu zvose zvakasikwa yakasimbiswa nokucherechedza kwomuchadenga, mamwe mashoko okucherechedza anogona kushandiswa kuisa mienzaniso pamuedzo. Kufanotaura, kwose kunobudirira, kunobatanidza kuwanda kwokutanga kwezvinhu zvemakemikoro zvakaumbwa munguva ye nucleosynthesis yapakuvamba, chimiro chakakura chechisiko chose, uye kuvapo nezvimiro zvekudzokorora kupisa kubva muchisiko chapakuvamba, mwaranzi yekunze yemuchadenga. Kucherechedza kwomuchadenga mwero wokuwedzera kwenyika kunobvumira kuyerwa kwechiyero chose chenyaya muchisiko chose, kunyange zvazvo chimiro chechinhu ichocho chichiri chisingazivikanwi murutivi. Inenge 90 yezvinhu zvose inoratidzika kuva chinhu chakasviba, icho chine uremu kana, zvakaenzana, pesvedzero yegiravhiti, asi hachibatanidzi electromagnetically uye, naizvozvo, hachigoni kuonekwa zvakananga. Hakuna rondedzero inogamuchirwa navose yorudzi rutsva urwu rwezvinhu, mukati megadziriro inozivikanwa yephysics yezvinhu zviduku kana kuti zvimwe. Uchapupu hwekucherechedza kubva kuongororo dze redshift dzema supernovae ari kure uye kuyerwa kwe cosmic background radiation kunoratidzawo kuti kushanduka kwechisiko chedu kunonyanya kukanganiswa ne cosmological constant inokonzera kukurumidza kwekuwedzera kwe cosmic kana, zvakaenzana, nechimiro chesimba neyakajairika equation yemamiriro, inozivikanwa seyakasviba simba, hunhu hwayo hunoramba husina kujeka. Chikamu chekuwedzera, chikamu chinowedzera chekuwedzera kwakanyanya kukurumidza panguva dze cosmic dzakatenderedza 1033 masekondi, chakafungidzirwa muna 1980 kuverengera kuongororwa kwakawanda kusinganzwisisike kwakange kusingatsanangurwe nemhando dzekare dze cosmological, senge kufanana kwakakwana kweiyo cosmic background radiation. Kuyerwa kwazvino uno kwemwaranzi yekunze yemuchadenga kwakaguma... Mubvunzo: Rudzii rwegiravhiti runoda mhinduro ine chiremera?  <response>: simba rinokwevera zvinhu pasi
