I-supernova kukufa okanye ukuqala kobomi obutsha?

Abantu abangaqhelekanga banokuyibona into enomdla njenge-supernova. Kodwa oku akukho ukuzalwa okuqhelekileyo kwenkwenkwezi, kuba kwi-galaxy yethu, ukuya kwiinkwenkwezi ezilishumi zizalwa ngonyaka. I-supernova yinto enokuthi ibone kuphela kanye kwiminyaka eyikhulu. Khanya kakhulu kwaye kuhle ukufa iinkwenkwezi.

Ukuqonda ukuba kutheni ukuqhuma kwe-supernova kwenzeka, kufuneka sibuyele ekuzalweni kweenkwenkwezi. Esikhathini, i-hydrogen izimpukane, eziqokelela kancane kancane emafini. Xa ilifu likhulu ngokwaneleyo, i-hydrogen enomlilo iqala ukuqokelela kwiziko layo, kwaye iqondo lokushisa liyakhula ngokukhawuleza. Ngaphantsi kwefuthe lobunzima, i-nucleus yeenkwenkwezi ezizayo ihlangene, apho ngenxa yokushisa okwandayo kunye nokwanda kwamanzi, ukuphendulwa kwe-thermonuclear fusion kuya kuqala. Ngakanani ubuninzi be-hydrogen abanokukhangela inkwenkwezi, kuxhomekeke kubukhulu bayo besikhathi esizayo - ukusuka kwibala elibomvu ukuya kwi-giant blue. Ngethuba lexesha, ukulingana komsebenzi weenkwenkwezi kusungulwe, iingqimba zangaphandle zicinezela kwi-core, kwaye i-nucleus ikhula ngenxa yombane we-thermonuclear fusion.

Inkwenkwezi yinto enjani ye- reactor reactor, kwaye njengawo nawuphi na u-reactor, ngolunye usuku iya kuphuma i-fuel-hydrogen. Kodwa ukuze ubone indlela i-supernova eqhume ngayo, ixesha elincinane kufuneka lidlulele, kuba kwi-reactor, endaweni ye-hydrogen, kwakhiwa elinye i-fuel (helium), eya kuqala ukutshisa i nkwenkwezi, ukuyijika ibe yi-oksijini, ibe yikhabhoni. Kwaye oku kuya kuqhubeka kuze kube yintsimbi yesiseko eyenziwa kwinqanaba leenkwenkwezi, okokuba, xa kuthathwa i-thermonuclear reactor, ayifuni amandla, kodwa uyayidla. Ngeemeko ezinjalo, ukuqhuma kwe-supernova kuya kwenzeka.

Umongo uba nzima kwaye uphawuleze, okubangelwa kwiindawo eziphezulu zokukhanya ziqala ukuwa kuwo. Kwakhona, impendulo ye-thermonuclear fusion isungulwe, kodwa ngoku ihamba ngokukhawuleza kunokuqhelekileyo, ngenxa yoko inkwenkwezi iqhuma nje, ichitha indawo yayo kwindawo ejikelezileyo. Ngokuxhomekeke kubukhulu beenkwenkwezi, emva kokuba kubuye kube neenkwenkwezi ezincinane. Izona zidumileyo ziyimimbobo emnyama (into ephethe ubuninzi obukhulu kakhulu, enegunya elikhulu kakhulu lokukhangela kwaye linokuphuma). Ezi zinjalo zihlala emva kweenkwenkwezi ezinkulu kakhulu, ezikwazi ukuvelisa i- thermonuclear fusion kwizinto ezinzima kakhulu. Iinkwenkwezi ezincinci zishiya i-neutron okanye insimbi yeenkwenkwezi ezincinci, eziphantse zingabikho ukukhanya, kodwa zinexinzelelo eliphezulu.

Entsha kunye ne-supernovae zihlobene ngokusondeleyo, kuba ukufa komnye wabo kunokuthetha ukuzalwa komntu omtsha. Le nkqubo iyaqhubeka ngokungenammiselo. I-supernova ihamba ngezigidi zeetoni zendawo kwindawo ejikelezileyo, ephinde iqokelele emafini, kwaye kwakhiwa iqela elitsha lasezulwini. Izazinzulu zithi zonke izinto ezinzima ezisemgangathweni wethu welanga, iLanga ngexesha lokuzalwa kwayo, "libi" kwi nkwenkwezi eqhutywe. Imvelo iyamangalisa, kwaye ukufa kwesinye into kuthetha ukuzalwa kwento entsha. Kwiindawo ezivulekile, umba udibene, kunye neenkwenkwezi zenza, ukudala ibhalansi enkulu yendalo yonke.
