Umntu unokucinga ukuba izimvo ezinje ngoMhlaba zijikelezile ngekhe zibe yingxabano ngeli nqanaba. Emva kwayo yonke loo nto, siye emajukujukwini kwaye sabona izinto. Ke, uyazi, nokuba yintoni. Kodwa kuyacaca ukuba bakho abantu aboneleyo apho uMhlaba ujikeleze khona ayisiyiyo ingxelo yokuba i-astrophysicist kunye noMchazi weNzululwazi weNzululwazi kubantu abaPhakathi, uNeil deGrasse Tyson, waziva isidingo sokujongana nale nkqubo yakhe, Thetha ngeNtetho .
Ujoyine umhlekisi u-Chuck Nice, uTyson ekuqaleni wanika impendulo elula kwi-flat-Earthers: Sinevidiyo. Ukusuka emajukujukwini. Ngokujikeleza, ukujikeleza komhlaba. Umhlaba ungqukuva. Yiyiphi, uyazi, ewe. Kodwa ngelixa beqhula beqala ukusonga incoko yabo, bagqibela ngokwenza ividiyo yemizuzu elithoba bethetha ngamaqhekeza obungqina obungqina ukuba uMhlaba ujikeleze. Ngaphezu koko, khange kuthathe inkqubela phambili yenzululwazi yanamhlanje kunye nobungqina bokufota ukuze abantu bayazi le nto. Abantu baye baqiqa ngelithi uMhlaba kufuneka ube yingqukuva ukusukela ngexesha lamaGrike amandulo.
UTyson uchaza uvavanyo olwenziwa ngamaGrike u-Eratosthenes, owayehlala e-Aleksandriya malunga ne-250 BC U-Eratosthenes uqaphele ukuba kwisixeko sase-Egypt sase-Syene (kufutshane ne-Aswan yanamhlanje), ungabona yonke indlela eya ezantsi kwequla emini ngexesha lasehlotyeni. Ukanti kwangolo suku lunye, wawungenakubona ezantsi kwequla eAlexandria.
Kwakhona uthetha ngento elula yokuba ngexesha lokusitheka kwenyanga, isithunzi somhlaba esichasene nenyanga sihlala sigobile. Ukuba umhlaba ubusicaba, isithunzi besinokubonakala sahluke kakhulu. Owu ewe, kwaye ke ikho into yokuba nabani na ochithe naliphi na ixesha kwizikhephe uyazi: xa isikhephe sihamba sisiya ngxi, kubonakala ngathi siyehla, siphela ukusuka kumbono ukusuka ezantsi ukuya phezulu. Oko ngekhe kwenzeke ukuba isikhephe sasihamba nje saya kuflethi engapheliyo.
Ngoku, ndiyazi ukuba uninzi lwenu olufundayo luyayazi yonke le nto, kodwa kuyamangalisa ukucinga ukuba kusekho abantu abangengobantwana ekufanele ukuba bacaciselwe oku. UTyson uthi:
Kwaye, into yokuba kukho ukunyuka kwe-flat-Earthers bubungqina bezinto ezimbini: Inye, sihlala kwilizwe elikhusela intetho ekhululekile. Kwaye ezimbini, sihlala kwilizwe elinenkqubo yemfundo engaphumelelanga. Inkqubo yethu kufuneka ikuqeqeshe, hayi kuphela kwinto yokwazi, kodwa nendlela yokucinga ngolwazi kunye nolwazi kunye nobungqina. Ukuba awunalo olo hlobo loqeqesho, uya kubaleka ujikeleze kwaye ukholelwe nantoni na.
Ividiyo ivala ngokukhankanywa kwe Indawo ekhangeleka kakhulu ebizwa ngokuba yiBrilliant.org , apho ungasayinela simahla kwaye ufunde okungakumbi malunga nesayensi kunye neekhonsepthi zezibalo ngendlela emnandi kunye nokudlalayo. Kungenxa yokuba ekuphela kwendlela yokulwa ukungazi kukwazi kunye nokufuna ukwazi okungapheliyo.
