Umqondo wosomkhathi basendulo abavakashela uMhlaba bevela kweminye imihlaba ube yisihloko esihlaba umxhwele amakhulu eminyaka. Abantu abaningi bakholelwa ukuthi izidalwa zakwamanye amazwe bezikhona emhlabeni wethu izigidi zeminyaka, futhi zishiye ubufakazi bokuba khona kwazo. Obunye ubufakazi obunjalo busanda kutholwa emanxiweni e-pyramid complex yasendulo - ichibi le-liquid mercury.

I-liquid mercury etholakala emakamelweni ephiramidi ingase yembule izimfihlo zosonkanyezi basendulo 1 — Ithempeli laseQuetzalcoatl elaziwa nangokuthi iPyramid of the Feathered Serpent Pyramid eTeotihuacan, eMexico. Ikhredithi Yesithombe: I-Adobe Stock

Ngo-2003, abavubukuli abahlola iThempeli Lenyoka Enezimpiko eMexico bathola into eshaqisayo - umhubhe oholela echibini le-mercury ewuketshezi ngaphansi kwesikhungo sephiramidi. Lokhu kutholakala kushiye ochwepheshe bedidekile, njengoba i-mercury ingenakukwazi ukuba khona esimweni sayo esiwuketshezi ngokwemvelo. Kumelwe ikhishwe kumaminerali ebizwa ngokuthi i-cinnabar, inqubo eyinkimbinkimbi edinga izinga lokushisa eliphezulu.

Okwenza lokhu kutholwa kuthakazelise nakakhulu ukuthi okuwukuphela kwendawo eyaziwayo ene-mercury ewuketshezi iseShayina, ngaphakathi kwethuna lika-Qin Shi Huang, umbusi wokuqala wobukhosi bakwa-Qin. Lokhu kuphakamisa imibuzo mayelana nokuhlobana kwalezi zimpucuko ezimbili zasendulo nokusebenzisa kwazo lesi sici esinobuthi.

Kodwa yini impucuko yasendulo eyayingayisebenzisela i-mercury? Impendulo ilele ezimpahleni zayo njenge-superconductor. Esikhathini sethu sobuchwepheshe besimanje, ama-superconductors asetshenziswa ezinhlelweni ezithuthukisiwe ezifana nokukhiqiza amandla mahhala, izithombe zezokwelapha, namaphrojekthi wezokuthutha. Kungenzeka yini ukuthi labo okuthiwa osomkhathi basendulo babesebenzisa i-mercury ngezinjongo ezifanayo?

Izinto ezithinta ukuthuthwa nokuphathwa kwe-liquid mercury nazo ziyamangaza. Okhokho bethu bahambisa kanjani inani elikhulu kangaka lale nto enobuthi ngaphandle kokuzilimaza? Futhi yayiyini injongo yokuwugcina ngaphansi kombhoshongo oseneminyaka ecishe ibe ngu-2,000 XNUMX ukhona?

Le mibuzo isenza sizibuze ngezinga lobuchwepheshe nolwazi lwempucuko yasendulo. Ingabe babekwazi ukufinyelela ubuchwepheshe obuphambili ababunikezwa izidalwa zakwamanye amazwe? Futhi uma kunjalo, kwenzekani kulolu lwazi ngokuhamba kwesikhathi?

Ukutholakala kwe-liquid mercury endaweni yasendulo yepiramidi kunezela isisindo esengeziwe emibonweni yabafokazi basendulo. Kusikisela ukuthi lezi zidalwa kungenzeka ukuthi zazikhona futhi zibambe iqhaza ekubumbeni umhlaba wethu kudala ngaphambi komlando orekhodiwe.

Ukuba khona kwe-liquid mercury ezindaweni ezimbili zasendulo ezihlukene kuphakamisa imibuzo eyengeziwe mayelana nokuxhumana kwalezi zimpucuko ezimbili. Ingabe kwakukhona uhlobo oluthile lokuxhumana noma uhwebo phakathi kwabo? Noma ingabe bobabili bathola ngokuzimela ukusetshenziswa kwe-mercury ngezinhloso ezifanayo?

Ukutholakala kwe-liquid mercury kunikeza nokukhanya mayelana nokwenzeka kobuchwepheshe obuphambili obukhona ezikhathini zasendulo. Izakhiwo eziningi zasendulo emhlabeni jikelele, njengamaphiramidi ase-Egypt naseNingizimu Melika, zibonisa ukunemba okumangalisayo namakhono obunjiniyela okunzima ukuwaphindaphinda ngisho nezindlela zethu zesimanje.

Ingabe le miphakathi yasendulo yayikwazi ukuthola ubuchwepheshe obulahlekile noma obulibalekayo ngokuhamba kwesikhathi? Futhi uma kunjalo, ingabe bebesizwa izidalwa ezihlala ngaphandle komhlaba?

Ukutholakala kwe-liquid mercury emakamelweni ephiramidi kuwubufakazi obubodwa obenezela empicabadala ezungeze izilwane zasendulo. Kubekela inselele ukuqonda kwethu umlando futhi kusivulela umhlaba wamathuba mayelana nesikhathi esidlule nekusasa lethu.

Ubani owaziyo ukuthi yiziphi ezinye izimfihlo nezinto esizitholile ezisilindile njengoba siqhubeka nokumba futhi sihlola amanxiwa ashiywe yimpucuko yasendulo? Mhlawumbe ngokutholwa ngakunye okusha, sizosondela ekwambuleni iqiniso ngemvelaphi yethu kanye nendima okungenzeka ukuthi izidalwa zakwamanye amazwe ziyidlalile ekubumbeni umhlaba wethu.
