Umqondo wobukhulu bomkhathi, kungakhathaliseki ukuthi awunamkhawulo noma cha, uye waba isihloko okuxoxwa ngaso amakhulu eminyaka. Kubalulekile ukuqaphela ukuthi lapho sibhekisela eMkhathini, sibhekisela ngokuqondile endaweni yonke ebonakalayo, ehlanganisa yonke into ekhiphe ukukhanya futhi yafinyelela emhlabeni wethu. Nokho, abantu abaningi bayazibuza okungaphezu kwendawo yonke.
Ngakho-ke, kulesi sihloko sizokutshela ukuthi yiziphi izinkolelo-mbono mayelana nalokho okungalé kwendawo yonke kanye nalokho okwaziwayo ngakho.
Yini engale komkhathi
Umbuzo wobukhulu bendawo yonke, ukuthi ayinasiphelo noma cha, sekuyisikhathi eside kuyisihloko sokucatshangelwa. Kubalulekile ukuqaphela ukuthi zonke izingxoxo ezijwayelekile mayelana ne-Universe abendawo ethile eyaziwa ngokuthi indawo yonke ebonakalayo, ehlanganisa zonke izinto zasemkhathini ukukhanya kwazo sekufinyelele eMhlabeni. Kodwa ingabe kukhona okungaphezu kwendawo yonke ebonakalayo? Futhi uma kunjalo, yini ekhona futhi inkulu kangakanani?
Iqoqo lemithala kanye nokwakheka okuhlukahlukene esingakubona njengamanje eMhlabeni kubizwa ngokuthi indawo yonke ebonakalayo. Lezi zindikimba zasemkhathini ziphambi kwethu ngoba ukukhanya nezinye izimpawu ezizikhiphayo ziye zahamba emkhathini futhi zafinyelela emhlabeni wethu kusukela ekuqaleni kwendawo yonke. Umkhathi obonakalayo uqondwa ngokujwayelekile ukuthi uthatha umumo oyindilinga, kanti iSolar System itholakala emnyombweni wawo.
Kumelwe kucaciswe ukuthi asiyona indawo egxile kuyo yonke indawo. Uma besingakhetha noma yimuphi umthala osendaweni yonke ebonakalayo bese sikhetha isimiso sonozungezilanga phakathi kwawo, besingathola ukuthi lesi simiso sonozungezilanga singaba nendawo emaphakathi endaweni yawo.
Ngaphezu kwalokho, kubalulekile ukuqaphela ukuthi ukwanda kwendawo yonke akubangelwa imithala esuka endaweni emaphakathi emkhathini. Kunalokho, kuwumphumela wokunwebeka kwesikhala ngokwaso, okuholela ekwandeni kwebanga phakathi kwemithala kuzo zonke izinhlangothi.
Ngenxa yokuthi yonke imithala ihlezi iqhelelana ngaphandle kwephuzu elihlanganyelwe lereferensi, umbono ngokuqinisekile uyoholela enkolelweni yokuthi imaphakathi nendawo yonke, nokuthi imithala esele ibonakala kuyiyo enyakazayo. beziqhelelanisa.
Ukunwetshwa kwendawo yonke ebonakalayo
Ukunquma ubukhulu bomkhathi obonakalayo kuwumsebenzi olula uma kuqhathaniswa. Ngokukala ibanga ukusuka eMhlabeni ukuya endaweni engaphandle, sithola ukuthi inweba ngaphezudlwana nje kuka-46 billion light years. Ngenxa yalokho, Ububanzi bayo bungalinganiselwa cishe eminyakeni yokukhanya eyizigidi ezingu-93.000.
Umbuzo ongase uphakame yilo: njengoba indawo yonke ineminyaka eyizigidi eziyizinkulungwane ezingu-13,7 ubudala, kungenzeka kanjani ukuba indawo yayo ingalingani naleyo, uma kucatshangelwa ukuthi akunakwenzeka kwanoma yini eyeqa ijubane lokukhanya? Isizathu salokhu ukungabikho kwesithako esibalulekile esatholwa ekhulwini leminyaka eledlule: ukwanda kwendawo.
Kuye kwatholakala ukuthi indawo yonke ibilokhu ikhula kusukela ekuqaleni kwayo. Ekuqaleni, lokhu kwanda kwabonakala kuhamba kancane kwaze kwaba cishe eminyakeni eyizigidi eziyizinkulungwane ezingu-5 edlule. Kodwa-ke, kusukela lapho belilokhu likhula ngesivinini esikhula ngokushesha, esilifaka kumandla angaqondakali aziwa ngokuthi amandla amnyama.
Yini elele ngale komkhathi obonakalayo
Nokho, yini elele ngale komkhathi obonakalayo, odlulela ngaphesheya inani elimangalisayo leminyaka yokukhanya eyizigidi eziyizinkulungwane ezingu-93.000? Ubukhulu bangempela bendawo yonke buhlala buyimfihlakalo.
Ngokusho kwezimiso zokuhlobana okukhethekile, kusungulwa ukuthi izinto ezisondelene kakhulu azikwazi ukudlula isivinini sokukhanya. Kodwa-ke, lo mthetho awusebenzi ezintweni ezikude, njengoba ukunwetshwa kwendawo ngokwayo kuvumela okuhlukile.
Ukucacisa, izinto okukhulunywa ngazo aweqi ngempela ijubane lokukhanya. Kunalokho, Ukwandiswa kwesikhala phakathi kwabo okubangela ukuhlukana kwabo okuphawulekayo, ifinyelela isivinini esikhulu kangangokuthi ukukhanya okukhishwa into ethile ngeke kufinyelele kwenye.
Kuyathakazelisa ukuthi lesi simo asiphuli noma yimiphi imithetho ye-cosmic. Nakuba ijubane lokukhanya lisebenza njengejubane elikhulu lezinto ezidlula emkhathini, alibeki mingcele ejubaneni lapho isikhala ngokwaso singakhula ngaso.
Uma kucatshangelwa inkolelo-mbono eyamukelwayo ye-inflation ye-cosmic, kusobala ukuthi indawo yonke engabonakali idlula indawo yonke ebonakalayo ngobukhulu obumangalisayo okungenani izikhathi eziyi-1023.
Empeleni, umbono wethu ulinganiselwe engxenyeni encane yomkhathi omkhulu womkhathi. Kodwa yini engekho ngaphezu kokubona kwethu? Ibukeka kanjani le ndawo yendawo yonke engahloliwe?
Kungenzeka kakhulu ukuthi ngaphandle kwemingcele yendawo yonke ebonakalayo kukhona indawo ebonisa lokho esikubonayo ngaphakathi kwayo: umkhathi omkhulu ogcwele imithala, izimbobo ezimnyama, ama-quasars, ama-pulsars, izinkanyezi, amaplanethi nokunye.
Indaba yokwandisa
Ekuqaleni kwekhulu lama-XNUMX, inkolelo eyinhloko yezazi zendawo yonke yayiwukuthi indawo yonke yanda ngokungenamkhawulo. Nokho, lo mbono washintsha lapho kuvela umbono wokuthi indawo yonke ifana nebhola likanobhutshuzwayo.
Ake sicabangele uMhlaba njengesibonelo esihle kakhulu. Kuyaziwa emhlabeni wonke ukuthi umhlaba uyindilinga enemingcele elinganiselwe. Nokho, uma umuntu ethatha uhambo kunoma iyiphi indlela, ngaphandle uma enquma ukumisa intuthuko yakhe, uyoqhubekela phambili engakaze afinyelele esiphethweni.
Ngesinye isikhathi, nakanjani sizobuyela endaweni efanayo, nakuba ngesikhathi esihlukile. Umqondo ophathelene nomkhathi wethu wukuthi unezici zendilinga enomkhawulo nengenamkhawulo. Ngenxa yalokho, uma umuntu enqamula umkhathi ngokungapheli, ekugcineni ubeyobuyela lapho eqala khona, ecabanga ukuthi ukwanda okungapheli kwendawo yonke akuyithiyi intuthuko yakhe.
Uma umuntu ebengase athathe uhambo lokunqamula umkhathi omkhulu wendawo yonke enemikhawulo kodwa engenamingcele, eqhubeka ehamba ngendlela eqondile emkhunjini, ekugcineni, ngemva kokuhamba kwesikhathi eside, ubeyofinyelela ngokungenakugwenywa umkhawulo wendawo yonke futhi athole. zibuyela endaweni yazo yokuqala, kuyilapho zigcina umzila oqhubekayo.
Umqondo owethulwe uhambisana kahle nenkolelo-mbono eyamukelwa kabanzi ye-Big Bang, ephakamisa ukuthi ukwakheka kwendawo yonke kungaba nale geometry ethile. Uma sicabangela ukuqala kokuqhuma okukhulu nokwanda okwalandela kwendawo yonke, Akukhona okungenangqondo ukucabanga ukuthi naphezu kobukhulu bawo, ingxenye ebonakalayo isikisela ukuthi indawo yonke ayinasiphelo.
Kungakhathaliseki ukuthi izinga leqiniso lendawo yonke liyaziwa noma cha, kubalulekile ukukhumbula ukuthi siyohlale sivalelwe ngaphakathi kwendawo yonke esiyibonayo, engaba nomkhawulo noma engapheli.
Ngethemba ukuthi ngalolu lwazi ungafunda okwengeziwe ngeminye yemibono mayelana nokuthi yini elele ngale komkhathi obonakalayo.
