"Izinto zokudla zasolwandle" ezingavamile zithusa ososayensi futhi zibeka usongo emhlabeni ophilayo ...
Ngezinye izikhathi izimfihlakalo zemvelo zibonakala ziyinto engavamile ngaphezu kobufakazi bokuba khona kwabafokazi noma ukuvela kwemimoya evela kwamanye amazwe. Emgodini osempumalanga we-United States nase-Australia iminyaka engaphezu kweyishumi, abantu bendawo bahlangabezane nezindawo ezingavamile eziluhlaza ebhishi, ukuchaza ukubonakala kwazo kusukela ekubukeni kwesayensi ngakho akekho owaziyo.
Umlando wokuthola okungavamile ogwini
Ngo-2002, edolobheni laseHotton, elisendaweni yase-Virginia yaseVrithani, abantu bathola ekuseni kakhulu olwandle "izipho" ezidalwa yi-Atlantic Ocean ubusuku bonke. Abazange bazise isipho sezakhi futhi ngokushesha babika emaphoyiseni. Abasebenzi bomnyango babiza ababiologists nezomvelo ukuthi bathathe izithombe bese bezithumele kwinethiwekhi.
Izinto ezitholakala zifakwe ebhokisini lombala omnyama omnyama, ubukhulu bebhola for tennis noma igalofu. Ugu lwalutholakala ngalo lungenani ngamamitha angu-300 ubude. Amabhola athathwe ukuhlolwa kwe-laboratory, futhi imiphumela yabo, yebo, yabalwa.
Mhlawumbe isintu singayikhohlwa ngale ndaba, siyilobe emaphethweni emvelo, kodwa kakade ngo-2014 amabhola afanayo awehla ngokuyisimangaliso kwelinye lamabhishi aseSydney e-Australia. Izibalo zezinto eziphilayo zasolwandle kufanele zibhalise lokho okufunayo bese zibuza abafologists usizo ekufundeni kwabo.
Izakhiwo ezinamandla zamabala aluhlaza
Isizathu sokuthi amabhola abangela ukukhathazeka phakathi kwezakhamuzi zamadolobha amabili e-US nase-Australia okufanayo. Kusuka kude, bafana nesiponji ukuthi, lapho ihlahlela amanzi, iyakhula kuze kube sezingeni lebhola lebhola. Yilokho kufana okwenza abantu bafinyelele kubo, okwakungesinqumo esingenangqondo, njengoba omunye wabafakazi bokuzibonela ethi:
"Umakhelwane wami, uMaria Segnery, wathola isitsha emanzini okubhekene nendlu yakhe yasebhishi e-Palm Island, wamyisa ebhishi elikhulu lolwandle. Ngenkathi indodana yakhe igibela kuye futhi yazama ukumthatha, kwaba yindlala kakhulu ukuba ingeniswe ogwini ngumuntu oyedwa. "
Esihlabathini noma emhlabathini, ibhaluni limile futhi lihlehliselwe usayizi walo wokuqala. Inomumo ophelele futhi uphunga njengelwandle, kodwa awunawo iphunga lomzimba wolwandle. Esimweni esomisiwe, ibhola lobulukhuni lifana nesilazi noma insimbi - futhi lilinganisa ngokunembile kakhulu kunalokho kubonakala ekuqaleni.
Kungani kungenakukwazi ukuchazwa yi-riddle yamabala aluhlaza ososayensi?
I-biologist eYunivesithi yaseSydney okuthiwa u-Ellen Getel uye wafunda impilo yasolwandle iminyaka eminingi, ngakho amaphoyisa amnika ilungelo lokuqala ukugibela ibhola. Njengo-Ellen, nabanye ososayensi abazi ukuthi lezi "zilwane zasolwandle" zivelaphi:
"Angikwazi ngisho nokunquma ukuthi imvelaphi yale nto ingukuthi - isilwane, i-mineral, noma enye into. Kubonakala sengathi mina ngenziwe ngokwenza kahle. Kungaba yinkimbinkimbi, kodwa ulwandle alukwazanga ukuwaphula futhi wenze zonke izinto ezilinganayo. "
Usosayensi wesifazane wasondela ekutholeni impendulo ngokuziphendulela futhi wanquma ukutadisha izincwadi zabanye bezinto eziphilayo, kodwa akazange athole noma yini phakathi kwabo ngamabhola amanzi. U-Ellen ukwesaba ukuthi angalimaza izilwane:
"Uma lesi sihloko siwela, njengesibonelo, singena esiswini kuya emahlathini futhi sizobuthelela lapho, lezi zilwane zasolwandle zizophela ngokulamba. Phela, izinyonikazi azikwazi ukugaya amabhola anjalo. Bayozizwa ukuthi isisu sigcwele, futhi sizoyeka ukudla. Izimpawu azikho lokhu, ngoba le nto ayiphunga inhlanzi. Kodwa ezinye izinhlanzi zingaba yiziphukuphuku ngokwanele ukugwinya okungaziwa. Ukunyakaza kwami kokuqala komphefumulo, lapho lezi ziqhingi zivela, kwakuzohamba futhi zisuse masinyane konke lokhu kusukela emabhishi. "
U-Ellen wabuza iseluleko ku-NASA - futhi waphendulwa. Njengoba abasebenzi be-agency base bejwayele amabhola aluhlaza atholakala ogwini e-US, bamema ososayensi ukuba basebenze ndawonye, hhayi ukubeka ucingo emrekhodini wokutholakala. Abalobi bephephandaba baphumelela ukuthola ukuthi emva kokuthuthela ebhokisithri yonke amabhola ahlukaniswa ngokungenasisekelo kokubili. Ngiyazibuza ukuthi ososayensi bakwazi yini ukuthola ngaphakathi kwabo?
