Ngo Cosmology, kusekhona impendulo ecacile yalo mbuzo, esithinta engu, ukuma Ubukhulu bezulu nomhlaba, futhi kungekho ukuvumelana mayelana imilenze yalo. Ngoba uma yonke ezilinganiselwe, khona-ke kumelwe noma ukuncipha noma ukwandisa. Kuleso simo, uma akupheli, ezizathwini abaningi lutho.
Emuva ngo-1744, isazi sezinkanyezi JF Cheseaux lokuqala angabaze ukuthi yonke obungapheli, ngoba uma inani lezinkanyezi alinayo imingcele engokoqobo, kungani hhayi shining isibhakabhaka futhi kungani amnyama? Ngo-1823, G. Olbes wagomela khona imingcele yonke ukuze ukukhanya eza Umhlaba okuvela ezinkanyezini ezikude kungabonakali kufanele babe buthakathaka ngenxa ukumuncwa ikhemikhali ungaphakathi indlela yabo. Kodwa kulokhu ngokwayo, yalolu ketshezi kufanele kube evuthayo bakhazimula futhi akukho okubi kakhulu kunanoma iyiphi inkanyezi. Lokhu kucatshangwa waqinisekiswa yesayensi yanamuhla, lapho ugomela ngokuthi cleaner kuyinto "lutho", kodwa ngesikhathi esifanayo ukuthi unesikhathi izakhiwo zangempela ngokomzimba. Yiqiniso, ukumuncwa cleaner amandla izinhlayiyana eziningi zokukhanya kuholela ekwandeni kwezinga lokushisa yayo, okuholela yokuthi cleaner buba umthombo yesibili yokukhishwa kwemisebe. Ngakho-ke, uma Ubukhulu bezulu nomhlaba elingapheli ngempela, izinkanyezi ukukhanya okuyinto Usufike ibanga umkhawulo shift eqinile ngakho obomvu oqala ukuze uhlangane ne ngemuva (zesibili) cleaner ngemisebe.
Nokho, ngolunye ongasho ukuthi Ubukhulu bezulu nomhlaba, okuyinto zigcinwe isintu Yiqiniso, njengoba ngokwayo sokugcina futhi ijubane lokukhanya. Ibanga 24 liwumngcele ukukhanya Gigaparseksa umkhathizwe yangaphandle. Nokho, ngenxa yokuthi ukuthi ukunwetshwa izinga ukwanda, ekupheleni umkhathi at ibanga 93 bhiliyoni iminyaka ukukhanya.
Umphumela ebaluleke kakhulu Cosmology kwakuwukuthi ukunwetshwa yonke sika. Kwakuthinta etholwe okwashiwo redshift, bese uthole ukuhlolwa ambalwa ngokuhambisana nomthetho wabantu bonke Hubble sika. Lokhu kwaholela ososayensi ukuba baphethe ngokuthi ithiyori Big Bang uthola isiqinisekiso yayo. Ngokusho NASA, eyayibonakala sitholwe WMAP, engu-yonke, kusukela Big Bang, iminyaka 13.7 bhiliyoni zilingana. Nokho, lo mphumela kungenzeka kuphela uma sicabanga ukuthi imodeli elisemandleni at ngesisekelo ukuhlaziya ilungile. Uma usebenzisa izinhlelo zokuklanywa kwentengo etholakala idatha ehluke ngokuphelele.
Ethinta okuphathelene nokwakheka kwendawo yonke, abakwazi ishiwo injalo. Kuze kube manje ayitholakalanga ukuthi ukuma ngakuthathu ukuthi ngabe umhlabeleli bamele umfanekiso waso. Lokhu nobunzima ubangelwa yokuthi kuze kube manje akwaziwa ukuthi yonke uyisicaba. Isici sesibili ihlobene yokuthi kungenxa ethile mayelana noxhumo yayo amaningi aziwa. Ngakho, uma Ubukhulu bezulu nomhlaba spatially iphahlwe, kolayini ngqo kunoma yisiphi isiqondiso kungaba yekucala.
Njengoba singabona, hhayi intuthuko kwezobuchwepheshe ifinyelele ezingeni ukuphendula ngokunembile imibuzo ephathelene nobudala, iyunithi kanye Ubukhulu bezulu nomhlaba. Kuze kube manje, mbono eziningi Cosmology baye alikaqinisekiswa, kodwa engakaze ngawo atholakala engenabufakazi.
