Isimiso sethu sonozungezilanga siyiqoqo lamaplanethi atholakala kuwo, iplanethi yethu eyikhaya: Umhlaba, kanye nezinye izinto zezinkanyezi ezizungeza ngokuqondile noma ngokungaqondile endaweni eyodwa ezungeza inkanyezi yelanga, kodwa ingabe unawo umbono?iyini iplanethi yokuqala eyakhiwe endaweni yethu?
Kunemibono eminingi mayelana nokudalwa kwendawo yonke, enye yemibono eyamukelwa kakhulu ososayensi i-Big Bang theory, ebizwa nangokuthi. Ukuqhuma okukhulu, lena imodeli evelele yesayensi yendawo yonke yezinkathi ezindala ezaziwayo zendawo yonke kanye nokuvela kwayo ngezinga elikhulu kwaba izinhlelo nemithala.
Inkulumo eyaziwa ngokuthiBIG BANG" inikelwe usosayensi wocwaningo lwamaNgisi UFred Hoyle, umhlaziyi owaziwayo wethiyori eshiwo, yona le, ukuze ayichaze kangcono le nto echazwa yilo mbono, wababaza ukuthi kwakumane kuwukuqhuma okukhulu.
Ngakho ukuze uthole ukuthi iyiphi eyokuqala wakha iplanethi noma kwakheka endaweni yonke yethu kumelwe siqale ngokwazi inkolelo-mbono yokudalwa kwendawo yonke yethu, eyanda njalo, kusukela ekuqhumeni kwayo okukhulu okukhulu.
Umkhathi njengoba siwazi ezikhathini zawo zakuqala wawugcwele, ngendlela efanayo futhi ngokwe-isotropically, amandla aminyene kakhulu futhi waba nezinga lokushisa elifanayo nokucindezela. Yabe isikhula futhi izinga lokushisa layo lehla, okwabangela izinguquko zesigaba ezifana nokufingqa kwesitimu noma ukubanda kwamanzi, ngobudlelwane obuqhubekayo nezinhlayiya eziyisisekelo.
Konke kwasuka kuBig Bang
Njengoba imijikelezo yesikhathi idlula, ezinye izindawo eziminyene kancane zento, cishe yasatshalaliswa ngendlela efanayo, yakhula ngamandla adonsela phansi, yabangela imizimba eminyene kakhulu, yakha amafu, izinkanyezi, imithala kanye nazo zonke ezinye izakhiwo zezinkanyezi esingazibona eplanethini yethu namuhla.
Ukwakhiwa kwezinhlelo zelanga: ukuthi kwaqala kanjani
Ngemva kwalokhu kuqhuma okukhulu kwe-cosmic, okungenani eminyakeni eyizigidi eziyizinkulungwane ezingu-4.600 edlule, iSolar System njengoba sazi ukuthi yayingeyona into engaphezu kweyodwa. ifu legesi elibandayo futhi uthuli, olwaziwa kangcono ngokuthi i-solar nebula, khona-ke amandla adonsela phansi aqala ukudlala, okwabangela ukuba izinto ziwele phezu kwawo, futhi lapho ziqala ukuzungeza, zaveza iLanga phakathi nendawo ye-nebula.
Iningi lenqwaba eyaqala ukuwohloka kancane kancane, yayisenkabeni ye-solar nebula, yakha i-solar nebula. inkanyezi enkulu, kuyilapho okunye kuhlakazekile kudiski ye-protoplanetary, kusukela lapho ukwakheka nokubunjwa kwamaplanethi, ama-satellites, ama-asteroids nezinye izidumbu ezincane zesimiso sonozungezilanga lapho sitholakala khona kwaqala. Funda kabanzi mayelana ne- ukutholwa kwamaplanethi ukuqonda kangcono le nqubo.
Thola okwengeziwe ngalesi sihloko lapha: 12 IMICIMBI YE-JUPITER EZOKWENZA UTHANDE UMHLABA KANYE NEZINYE IZIMPANGASO
Kunezifundo eziningana ngemvelaphi yendawo yonke
Ngenkathi i-solar core accretion model theory isebenza kahle kumaplanethi asemhlabeni, ama-gas giants ngabe ziphenduke ngokushesha ukubamba inani elikhulu lamagesi alula aqukethe okwamanje. Ungathola okwengeziwe mayelana amaplanethi esimiso sonozungezilanga ukuze uthole umbono obanzi.
Ososayensi baye bahlakulela imibono kanye nokulingiswa okwenziwe, okungazange kukwazi ukulandisa ngokubunjwa okusheshayo kwesimiso sonozungezilanga. Ngokusho kwamamodeli, inqubo ithatha iminyaka eyizigidi ezimbalwa, isikhathi eside kunesikhathi amagesi alula atholakala ku-Solar System encane.
Ngokufanayo, i-core accretion theory idala inkinga yokufuduka, ngoba mhlawumbe amaplanethi amancane angawela ijika elibheke elangeni ngesikhathi esifushane.
Ikusasa lesimiso sethu sonozungezilanga
I-nebulae enkulu neminyene yakha isimiso sezinkanyezi esiwaziyo
Funda kabanzi ngalesi sihloko ku: Imibono Vuliwe Indalo Okwendawo yonke
ILanga liya likhanya ngezinga elicishe libe ngamaphesenti ayishumi njalo 1000 izigidi zeminyaka. Kulinganiselwa ukuthi phakathi neminyaka eyibhiliyoni eyodwa, ilanga liyobangela ukushisa okungalawuleki kweplanethi enguMhlaba, okubangele ukuba ulwandle, imifula namachibi kuqale ukuhwamuka njalo. Kuyathakazelisa futhi ukwazi mayelana neplanethi iVenus, etholakala esimisweni sethu sonozungezilanga.
Cishe eminyakeni eyizigidi eziyizinkulungwane ezingu-6, imithombo ye-hydrogen engaphakathi kwenkanyezi yethu yeLanga izobe isiphelile futhi izoqala ukusebenzisa lezo ezisezingqimbeni zayo ezingaphezulu ezingaminyene kakhulu futhi, ngokungaphezulu noma kususwe iminyaka eyizigidi eziyizinkulungwane ezingama-7,6 esikhathini esizayo, lizoba umdondoshiya obomvu, libandayo futhi lifiphazwe ngenxa yendawo yalo eyanda kakhulu. Njengoba iLanga likhula lizomunca iMercury neVenus futhi ngokunokwenzeka neplanethi yethu eluhlaza okwesibhakabhaka.
ILanga liwukuphela kwenkanyezi emaphakathi yesimiso sonozungezilanga, inquma konke ukuziphendukela kwemvelo kanye nesiphetho samaplanethi akha iplanethi yethu. iplanethi eyinkimbinkimbi; ngalo mqondo, ilanga liyinkanyezi eseduze kakhulu noMhlaba kanye nendikimba yasezulwini ekhanya kakhulu. Le nkanyezi inesibopho salokho esikushoyo, imini nobusuku, isiqalo nesiphetho sethu sansuku zonke.
Esinye isibikezelo sesayensi noma ukuchazwa kochwepheshe ukuthi eminyakeni eyizigidi eziyizinkulungwane ezingu-3000, neLanga lisakhona ukulandelana okuyinhlokoI-Andromeda, umthala oseduze, izosondela kumthala wethu, okuyobangela ukungqubuzana okuseduze, kukhiqize ukusebenza kwayo yomibili imithala. Ungahlola kabanzi mayelana I-Jupiter namanye amaplanethi ukuqonda kangcono izici zayo.
Kodwa-ke, nakuba kungase kuthinte isimiso sethu sonozungezilanga, akunakwenzeka ukuthi kungathinta iLanga noma amaplanethi, ngenxa yebanga elikhulu lapho izinkanyezi ziqhelelana khona, eqinisweni, endaweni. icala lokucabanga Lapho kungqubuzana okukhulu phakathi kwemithala, maningi amathuba okuthi isimiso sonozungezilanga sijikijelwe endaweni ekuyo manje futhi sigcine sisonqenqemeni lomthala osanda kwakhiwa phakathi kwalezi zixuku ezimbili.
I-Solar System esizungeza kuyo itholakala kweyodwa yezingalo ezintathu ezinkulu ezizungezayo zomthala we-Orion, ibanga eliqhele ngeminyaka yokukhanya eyizinkulungwane ezingama-32 ukusuka ku-nucleus, ejikeleza ngesivinini esingavamile esingamakhilomitha angama-250 ngomzuzwana, isebenzisa iminyaka eyizigidi ezingama-225 ukwenza uguquko oluphelele, olungahambisana unyaka we-cosmic.
Ngakho singasho ukuthi asazi ngokuqinisekile ukuthi iyiphi iplanethi yokuqala eyadalwa, nokho, siyazi ukuthi inkanyezi yokuqala eyakha isimiso sethu samaplanethi kwakuyilanga, ngokuvamile, eliwumthombo wokuphila kwethu. , ukuthuthukiswa kanye nokuziphendukela kwemvelo.
