Okunye ukukhathazeka okukhulu esinakho njengabantu ukubikezela, ngandlela thile, ukuthi sizokufa kanjani futhi nini. Ithimba lezazi zezinkanyezi kubonakala sengathi likuthathe lokhu njengoba, njengoba besho, ngenxa yochungechunge lwezibalo kanye nokuqhathanisa abakwazile ukukwazi ilanga lizofa kanjani futhi nini futhi, ngalo, lonke uhlelo lwethu lweSolar.
Ngaphambi kokuqhubeka, ake ngikutshele ukuthi kusekhona isikhathi eside kuze kwenzeke lokhu, okungenani uma sibheka izibalo ezenziwe yileli qembu labaphenyi, kangangoba akekho noyedwa kithi oqoqwe nxazonke kulokhu kungena ongakuphila futhi noma lokho, mhlawumbe lokhu kuza ngaphambili, ngeke kube khona muntu ngaleso sikhathi.
Ngokuqhathanisa, iLanga kufanele life eminyakeni eyizigidi eziyizinkulungwane eziyishumi
Ngokuya ngezibalo ezenziwe nezishicilelwe, singakuqonda lokho Namuhla iLanga cishe lineminyaka engama-4.6 billion likhona okudala. Le minyaka ikalwe ngemuva kokuyiqhathanisa nezinye izinto eziseSolar System ezakha ngasikhathi sinye. Ngokusekelwe ekuhloleni nasezifundweni zezinye izinkanyezi ezikhona emkhathini, izazi zezinkanyezi ezisebenze kulo msebenzi zikubikezela lokho ILanga lizofa ngesinye isikhathi lapho isikhathi sokuphila salo sifinyelela eminyakeni eyizigidi eziyizinkulungwane eziyishumi.
Manje, lokhu akusho ukuthi impilo eSolar System iyathandeka kanjalo, kepha ukuthi ezibikezelweni kuyamenyezelwa ukuthi lapho iminyaka yeLanga ifinyelela Eminyakeni eyizigidi eziyizinkulungwane ezingama-5 eyedlule, izoqhubeka ibe yisigebenga esibomvu. Lokhu kusho ukuthi umnyombo wenkanyezi uzoncipha njengoba izingqimba zawo ezingaphandle zikhula zize zifinyelele emzileni we-Mars. Ngenxa yalokho, lezi zingqimba zizosibekela ekukhuliseni kwazo uMhlaba noma yini, ngaleso sikhathi esithile, engahlala kuwo.
Ukwanda kwaminyaka yonke kokukhanya kweLanga kungabulala impilo eMhlabeni ngokushesha okukhulu kunalokho esicabanga
Ukuze lokhu kwanda kwenzeke kusasele iminyaka engaba ngu-400 ngaphambili, isikhathi esibonakala siside kakhulu kodwa lapho kuzophinde kwenzeke khona izinto ezizodala ukunwetshwa. Kulesi sikhathi kulindeleke ukuthi iLanga, njengoba kwenzeka, yandisa ukukhanya kwayo ngo-10% njalo eminyakeni eyizigidigidi okuthi, ngokusho kwabaphenyi, kuzoqeda impilo eMhlabeni.
Inkinga yokuthi ukukhanya kweLanga kuyanda unyaka nonyaka, yize kulesi sikhathi esifushane cishe kungabonakali kithi, ukuthi amazinga okushisa nawo azokwenyuka, okungagcina kube nezinkinga ezinkulu njengokuthi ulwandle ekugcineni lunyamalale, Ubuso beplanethi bushisa kakhulu ukuba amanzi akhe kuwo futhi, ngakho-ke, iplanethi ihlala iketshezi, okuthile, njengoba sazi, kubalulekile ekuqinisekiseni ukuphila emhlabeni.
Ngemuva kokuthi iLanga liphenduke isigebenga esibomvu lizoncipha libe mhlana omhlophe
Ngemuva kweminyaka eyizigidi ezingama-5.000 XNUMX, ngokocwaningo olushicilelwe yileli qembu lezazi zezinkanyezi, kuzokwenzekani kunzima kakhulu ukunquma. Yize kunjalo, njengoba kungafundwa kulo mbhalo, kungenzeka kakhulu ukuthi iLanga lethu lizosuka esidlekeni esibomvu liye emhlolweni omhlophe ukuze ligcine liguquke laba yi-nebula yamaplanethi, ekugcineni okukhomba ukuphela kweSolar System yethu. Njengoba u-astrophysicist ephawule U-Albert Zijlstra, omunye walabo ababhekele ucwaningo kanye noprofesa ku- IManchester University:
Lapho inkanyezi ifa, ikhipha inqwaba yegesi nothuli esikhaleni elingafinyelela uhhafu wesisindo senkanyezi. Lokhu kuveza umnyombo wale nkanyezi, okuthi ngalesi sikhathi empilweni yayo iphele uphethiloli, igcine ivaliwe futhi ekugcineni ife.
Kungaleso sikhathi kuphela lapho umongo oshisayo wenza imvilophu exoshiwe ikhanye cishe iminyaka eyi-10.000 XNUMX, isikhathi esifushane kusayensi yezinkanyezi. Yilokhu okwenza i-nebula yeplanethi ibonakale. Ezinye zicwebezela kangangoba zingabonakala ebangeni elide ngokwedlulele elinganisa amashumi ezigidi zeminyaka yokukhanya, lapho inkanyezi uqobo lwayo ibingaba buthakathaka kakhulu ukuba ingabona khona.
