Enye yezimfihlakalo ezinkulu ezingakaxazululwa endaweni yonke empeleni akuzona izinkulungwane nezigidi ezivela eMhlabeni ngoba namanje asazi into elula kangako, noma cha, njenge imvelaphi yenyanga. Ngemuva kwezinsizakusebenza eziningi ezitshalwe ocwaningweni nasentuthukweni, kube nemibono eminingana eye yabona ukukhanya, ngokumangazayo futhi njengoba wazi, akukho nokukodwa okuke kwafakazelwa.
Kuleli qophelo, ngikutshele ukuthi impela, kwesinye isikhathi, kungenzeka ukuthi uke wezwa noma wafunda ukuthi i- Inyanga yaqala ngenxa ye- ukushayisana kwento enkulu, cishe ngobukhulu beMars, ngokumelene nomhlaba, ngoba ingenye yezinkolelo-mbono ezisakazeke kakhulu. Le nto, yabhapathizwa njenge I-Theia, kubangele ukuthi kwethulwe amathani amadwala nothuli esikhaleni kwagcina kwakheka iNyanga njengoba sazi. Njengokuningiliziwe, akutshele ukuthi kule mbono ngo-2014 kwashicilelwa ucwaningo olwanikeza ubufakazi bokuthi izinhlayiya zeThiya zitholakale kanjani ekwakhiweni kwamakhemikhali eNyanga, kodwa lezi azikaze zithathwe njengeziphelele nganoma yisiphi isikhathi.
Isibonelo somunye umbono ohluke kakhulu kunowangaphambilini usitshela ukuthi kanjani iNyanga yavele yakha njengenye into ngesikhathi kudalwa amaplanethi weSolar System. Imane nje ijikeleze uMhlaba ngoba, ngaleso sikhathi, wawusondele kakhulu emhlabeni wethu, futhi ngenxa yamandla adonsela phansi, ekugcineni iNyanga yagcina izungeza wona.
Kunemicabango eminingi esitshela ukuthi iNyanga yakhiwa kanjani ngenxa yomthelela wento enkulu. Lokhu akuyona ukuphela kwembono ngakho
Ngaphandle kwakho konke lokhu, namhlanje sihlangana ukukhuluma ngomqondo wokuthi isazi sezinkanyezi sisanda kusiphakamisa USara stewart ngokuhlanganyela nethimba lakhe labaphenyi abavela ku University of California. Kulo mzamo wokugcina wokuchaza imvelaphi yeNyanga, kwethulwa umqondo ebesingazi kuze kube manje futhi obhabhadiswe ngegama lika I-Synestia, ingxube yamagama uSin (ndawonye) noHestia (unkulunkulukazi wamaGrikhi wezakhiwo).
Lapho sesazi lo mqondo omusha, iqembu labaphenyi lisitshela lokho ISynestia yilokho okwenzekayo lapho amaplanethi amabili osayizi ofanayo ehlangana ngodlame olukhulu. Ngenxa yalokhu kushayisana, inani elikhulu lezinto eziphonswayo lilahlelwa emkhathini, idwala elincibilikisiwe nelincibilikisiwe, eliqala ukuzungeza ngesivinini esikhulu lenze umumo ofana nowedonathi. Lapho leli fu liqala ukuphola, lidala ukuthi izinto ezikulo zihlangane zenze iplanethi entsha. Ukuze lokhu kwenzeke, kufanele kudlule isikhathi esiphakathi kweminyaka eyikhulu kuya kwengama-100.
Ukufaniswa kwalo mbono omusha oshicilelwe nguSarah Stewart kuyavumelana kakhulu
Ngokusobala futhi njengoba kuxoxiswene ephepheni lapho ithimba leYunivesithi yaseCalifornia lishicilela khona imiphumela yalo, kuthiwa icala elithile ekwenziweni kweNyanga belihluke kakhulu kusukela, ngemuva kokushayisana okwakha iSynestia eyakha uMhlaba, eceleni kwayo kwaqala ukwakheka into yesibili. Le nto yesibili yayihlanganisa izinto kuze kube, lapho kufika isikhathi, yavela efwini yaqala ukuzungeza into enkulu kunazo zonke, kulokhu, okuzoba nguMhlaba.
Okwamanje konke lokhu kuyimfundiso nje, yize, kususelwa ekulingiseni okwenziwe nguSarah Stewart nethimba lakhe ngokuhlanganyela, kubonakala sengathi imiphumela iyafana. Ngokulandelayo, lo mbono uchaza okunye ukungabaza okukhulu bonke ososayensi abanakho, into elula njengaleyo kungani iNyanga yabelana ngengxenye yokwakhiwa kwayo kwamakhemikhali noMhlaba, kodwa hhayi bonke.
Ukuchaza okwakamuva, iqembu ngqo lithi, esigabeni sokuqala, njengoba umhlaba neNyanga kwakhiwa ngaphakathi kweSynestia efanayo, bobabili bangeze izinto ezisinda kakhulu kuqala ukwakheka kwayo ngendlela yokuthi ezinye izinto ezilula ukuhwamuka, njenge potassium, isodiyamu kanye ne-zinc, bezingenaso isikhathi sokuzengeza kuleyo Nyanga yakudala ukuze ziwele ngokuphelele eMhlabeni.
