I-Bloody Falls iyisimangaliso semvelo esimangalisayo esenza abantu bacabange ukuthi kungenzeka ukuthi kuphila eMars kusekhona. Umfudlana obomvu wegazi ugeleza uvela ezinguzungeni zeqhwa e-Antarctica, okubonakala kungajwayelekile ezimeni ezinzima kangaka. Isikhathi eside, bekuxoxwa ngokuqagela kuphela kwesimo esinjalo, kepha namuhla ososayensi bathole incazelo yalesi simanga esimangazayo.
Umlando wocwaningo lweGazi Falls
Ngokokuqala ngqá, uGriffith Taylor wahlangabezana nesimo esingajwayelekile eningizimu yomhlaba ngo-1911. Ngosuku lokuqala nje lohambo lwakhe, wafinyelela ezinguzungeni zeqhwa ezimhlophe njengeqhwa, kwesinye isikhathi zimbozwe ngamabala abomvu. Ngenxa yokuthi emvelweni sekuvele kunezimo ezaziwayo zokungcola kwamanzi ngombala obomvu, usosayensi uphakamise ukuthi i-algae kufanele isolwe. Indawo lapho kuvela khona lo mfula ongajwayelekile selokhu kwaziwa njengeTaylor Glacier ngokuhlonipha usosayensi owutholile.
Kamuva ngo-2004, uJill Mikutski waba nenhlanhla yokubona ngamehlo akhe ukuthi iGazi Falls ligeleza kanjani eqhweni. Ubelokhu elinde lesi simo izinyanga ezingaphezu kweziyisithupha, ngoba isimangaliso semvelo asihlali njalo. Leli thuba eliyingqayizivele lamvumela ukuba athathe amasampula wamanzi agelezayo futhi athole isizathu sombala obomvu.
Sikukwazisa ukuthi ubheke iMpophoma i-Iguazu.
Njengoba kwenzeka, kusolwa amabhaktheriya, azivumelanise nokuphila ngaphandle komoya-mpilo ezinzulwini ezifihlwe yiqhwa. Ezigidini zeminyaka eyedlule, leli chibi lalimbozwe izingqimba zeqhwa, ezazincisha izinto eziphilayo kulo. Bambalwa kuphela kubo abaye bafunda ukondla ngensimbi, beguqula amakhemikhali amathathu abe yizincomo. Ngakho-ke, kunenqwaba yokugqwala okungcolisa amanzi echibi elingaphansi komhlaba.
Njengoba i-oksijini inganikezwa lapho, ukuminyaniswa kasawoti kuphakama kaningana kunasemanzini aseduze. Lokhu okuqukethwe akuvumeli ukuthi uketshezi lubande ngisho nasemazingeni okushisa aphansi, futhi lapho inani elikhulu lamanzi liqoqeka futhi licindezelwa, liphuma ku-Taylor Glacier bese lipenda yonke indawo ezungezile nge-hue ecebile enegazi. Izithombe zalo mbukwane ziyamangaza, njengoba kubonakala sengathi uMhlaba ngokwawo uyopha.
Ingabe kukhona ukuphila eMars?
Lokhu kutholwa kwavumela ososayensi ukuthi bazibuze ukuthi akhona yini amagciwane anjalo ekujuleni kwe-Mars angenza ngaphandle kwe-oxygen. Ucwaningo lukhombisa ukuthi izinto ezifanayo zazibonwa ezindaweni ezahlukahlukene kwiplanethi eseduzane, kepha akekho noyedwa owayengacabanga ukuthi kwakudingekile ukutadisha okujulile, hhayi ubuso. I-Bloody Falls yaba yisasasa, yadala ukucabanga okusha ngokuba khona kwabafokazi, noma ngabe kuyizinto ezilula kakhulu.
