NgoJanuwari 2019, kwatholwa izinto zobuciko ezimbalwa ezingaqondakali ngasogwini lwaseFlorida e-United States. Ubudala bawo babusobala, kodwa imvelaphi yawo yayingaziwa. Sekukonke, izinto eziyisikhombisa zawela ezandleni zososayensi. Zonke zidalwe ngethusi, igolide, isiliva kanye nezinto ezibalulekile ezingatholakali emhlabeni - iridium.
Yiqiniso, lezi zinto zadalwa ngezandla zabantu nasezimweni zasemhlabeni impela. Iqiniso liwukuthi i-iridium itholakala ngobuningi kuma-meteorite awile. Ngokusobala, abantu basendulo basibona “isibonakaliso” esivela ezulwini futhi basilandela. Ngemva kokuthola itshe eliyigugu kakhulu, baqala ukwenza izinto zehlelo.
Ukuhlaziywa kwezinto zokwenziwa kwabonisa ukuthi okungenani zineminyaka eyi-10,000-12,000 ubudala. Uma kucatshangelwa ukuthi i-iridium iyinto ephikisayo kakhulu futhi eqinile, kufanele kubhekwe kabusha izinga lokujula kwe-metallurgy phakathi kwabadala bakuleyo ndawo.
Ngokunokwenzeka, lezi zinto ngezazo, futhi kunjalo, impucuko yasendulo yayinolwazi oludlulele kulezo zindawo ezingakanqotshwa isintu sesimanje. Ngakho-ke, akungabazeki ukuthi ongcweti bakwazi ukwenza le misebenzi yobuciko ezinkulungwaneni zeminyaka edlule.
Okwakuthakazelisa kakhulu kwakuyisifihla-buso sikankulunkulu uViracocha. Ubukhulu bayo buyi-1.7 mm kuphela. Ngesikhathi esifanayo, kukhona umdwebo wonkulunkulu omkhulu nezimpawu ezihlukahlukene zenkolo kuwo.
Kuyaziwa ukuthi ngaphambi kokufika kwabanqobi, impucuko ye-Inca yabhekana nomlando wayo. Ukuze kuqondwe, kufanele kushiwo ukuthi phakathi kuka-1,200 no-1,500 AD, amaInca ayekwazi ukusebenza ngobuciko kuphela ngegolide, isiliva nezinye izinsimbi ezincibilika kancane.
Izithando zabo ze-metallurgical zakhiqiza amazinga okushisa angaphezu kuka-1300 degrees. Ukuze uncibilikise i-iridium, kufanele isondele kakhulu kuma-degree angu-2500.
Isithombe sikankulunkulu uViracocha sikuvumela ukuthi unqume ngokunembile umsuka we-artifact ― yadalwa ama-Inca. Nokho, umlando wanamuhla ubonisa ukuthi uMbuso Wama-Inca ungomunye wempucuko encane kunazo zonke. Pho bakwenze njani? Futhi lezi zinto zobuciko zingaba kanjani iminyaka eyi-10,000-12,000 nhlobo? ― Lena imibuzo edidayo, lapho abacwaningi benwaya khona amakhanda.
Abaningi bacabanga ukuthi izazi-mlando ezivamile zilifihla ngamabomu iqiniso ngama-Inca asendulo noma zazi okuncane kakhulu ngesiko lawo eliyiqiniso. Khumbula, ama-Anglo-Saxon abhubhisa umlando omkhulu wamaNdiya, kangangokuthi kwaba nomuzwa wokuthi iMelika ayakhiwe hhayi ekufeni kwempucuko yamaNdiya, kodwa ezindaweni ezihlala izizwe ezingafundile.
Ulwazi lwethu lunikezwa ukuhlanzwa okufanayo. Umlando awunakwethenjwa. Siyabonga uNkulunkulu, izinto zobuciko ezifana nalezi zisiza ukuthola iqiniso elikhohliwe (elinqatshelwe).
