Ukuphela kwehlabathi, inkqubo ecothayo kwinqanaba lomntu, sele iqalile kwaye iyakuphela ngokunyamalala kobomi e Umhlaba, malunga neminyaka engama-500 ezigidi.
Kuqhelekile ukuba Umhlaba iyakutshatyalaliswa ngokufa kwelanga, kwiminyaka eziibhiliyoni ezisixhenxe ukusukela ngoku. Ewe kunjalo, abaphandi abaziincutshe kwindaleko yeenkwenkwezi bayazi ukuba iinkwenkwezi zizalwa zize zife ngokwamkela iifom ezintsha kunye neempawu ezithi zenze utshintsho olukhulu kubume bendawo. Inkqubo ye- ilanga Iyakhanya ngenxa yokuba iyayitshisa ipetroli, i-hydrogen, eguqukela kwi-helium kwinkqubo ye-fusion yenyukliya.
Kumawaka ezigidi zeminyaka ukusukela ngoku, le reserve izakuqala ukusilela, ilanga Iya kuthi emva koko ithathe i-hydrogen kwiqokobhe langaphandle le-nucleus yayo, kumaleko kufutshane nomphezulu welanga. Ngenxa yoko, imingxuma yelanga iya kukhula ngokuthe ngcembe, ize inyuse umoya inkanyezi ubungakanani bayo buya kuphindaphindwa ngo-200.
El helio ingqokelela entliziyweni yelanga iya kuthi emva koko iqale ukuxubana ukwenza ikhabhon kunye neoksijini, ngelixa kumda, kwigobolondo elijikeleze intliziyo, hydrogen iya kuhlala inyibilika. Amandla akhutshiweyo aya kuthi emva koko aqapheleke, kwaye inkwenkwezi iya kuba yindlela enkulu ngokuphindwe kalishumi kunelanga langoku.
Ububanzi be sol izakuqhubeka nokufaka kunye nokudibanisa iiplanethi zokuqala zenkqubo, iMercury kunye Venus, eya kuthi i-7 ichithakale, ngelixa uMhlaba kunye noMars ngokuqinisekileyo uza kutshiswa.
Emva kweminyaka eli-12.000 lezigidi ikhona, yethu iplanethi izakufunxwa lilanga, iguqulwe ibe sisigebenga esiya kutshabalalisa nawuphi na umkhondo wobukho babantu nokusasaza iimolekyuli neeathom zakudala Umhlaba kwisithuba.
Ngokuphathelele ilanga, ukulingana kwalo, njengesigebenga esibomvu, kuya kungazinzi, kwaye isiseko selanga ekugqibeleni siyanyibilika, sijolise space phakathiecaleni Ubume bangaphandle belanga elifayo ngohlobo lwe-nebula.
Las iziphumo baya kuba yintlekele emhlabeni. Ngokuthe ngcembe amaqondo obushushu omhlaba akazukunyamezeleka, kwaye izidalwa zasemhlabeni ziya kuzimela emanzini. Ngabo kuphela abanokuziqhelanisa nobume bamanzi abaya kuhlala ixesha elithile. Kodwa ekuhambeni kwexesha, iilwandle ziya kushushu kangangokuba zibulale naziphi na iintlobo zobomi ezinzima. Ekugqibeleni, izinto uyaphila ziya kutshiswa kwaye iilwandle ziyaphuphuma. Ngale ndlela, ukuphela komntu kufanele kufike kude kube sekupheleni kwe Tumhlaba Ngaphakathi kuye.
