Izwekazi elikhulu nelingaqondakali le-Antarctica belilokhu liwumthombo wokuthakazelisa kanye nozungu kubahloli bamazwe, ososayensi, kanye nabaqambi bozungu ngokufanayo. Ngenxa yesimo sezulu esibi kanye neqhwa, indawo eseningizimu yeplanethi yethu isalokhu ingaziwa futhi igubuzelwe yimfihlakalo. Abanye bakholelwa ukuthi leli zwekazi liyikhaya lempucuko yasendulo, izizinda zamasosha eziyimfihlo, ngisho nokuphila kwamanye amazwe. Abanye baphikisa ngokuthi inhloso yangempela ye-Antarctica ifihliwe emehlweni omphakathi yiqembu elinethunzi labathile.
Ngaphezu kwalokho, amathiyori e-Flat Earth asakazwa iminyaka, kodwa inkambiso yakamuva ku-inthanethi yengeza enye into kulo mbono - isimangalo sokuthi umhlaba uzungezwe udonga lweqhwa.
Beyond The Great South Wall: The Secret of the Antarctic yincwadi ka-1901 kaFrank Savile. Empeleni alukho “udonga olukhulu lweqhwa” ekupheleni komhlaba. Umhlaba uyimbulunga, okusho ukuthi awusicaba. Kungase kube nezindonga zeqhwa ezwekazini lase-Antarctica, kodwa ngaphandle kwazo kuneqhwa, iqhwa nolwandle.
Umqondo wodonga lweqhwa elizungeze umhlaba uyinganekwane futhi awunakwenzeka ngokwesayensi, kusho ochwepheshe.
I-Antarctica iyizwekazi eliseNingizimu nenkabazwe. Idatha yesathelayithi ibonisa ukuthi ayinwebeki kuwo wonke umhlaba. Ngaphezu kwalokho, udonga lweqhwa ngeke luqhubeke, kusho ososayensi base-Antarctic.
I-Antarctica iyizwekazi eliseNingizimu nenkabazwe. Isathelayithi idatha evela NASA futhi izinkampani ezizimele zibonisa inqwaba yomhlaba njengesiqhingi esinesiphetho esiqondile.
Ngaphezu kwalokho, i-glacial geologist Bethan Davies yathi ngeke kwenzeke ukuthi udonga lweqhwa obekucatshangwa ukuthi lube khona ngaphandle kwenhlabathi exhunywe kulo.
Abantu bebelokhu behlola isifunda sase-Antarctic kusukela ngasekupheleni kwawo-1760. Abantu abaningana baye balizungeza leli zwekazi, obekungeke kwenzeke ukuba “bekuwudonga lweqhwa oluzungeza lo Mhlaba oyisicaba.”
Ngakho-ke, isimangalo sokuthi i-Antarctica iwudonga lweqhwa oluzungeze umhlaba oyisicaba ingamanga ngokuphelele. Isithombe sesathelayithi sibonisa umumo wezwekazi, okungelona udonga lweqhwa emhlabeni jikelele. Abahloli baye bazungeza insimu, futhi abantu bayayivakashela minyaka yonke. Ngaphezu kwalokho, umqondo wodonga lweqhwa nawo awulona iqiniso ngokombono wesakhiwo.
