Isazi se-Astrophysicist uRon Mallett ukholelwa ukuthi usethole indlela yokubuyela emuva ngesikhathi - ngokwethiyori. Uprofesa we-University of Connecticut we-University of Connecticut usanda kutshela i-CNN ukuthi ubhale i-equation yesayensi engasebenza njengesisekelo somshini wesikhathi sangempela. Uze wakha idrive prototype ukukhombisa ingxenye esemqoka yethiyori yakhe - yize ontanga bakaMallett behlala bengaqiniseki ukuthi umshini wakhe wesikhathi uzophumelela.
Ukuze uqonde umshini kaMallett, udinga ukwazi izisekelo zomqondo ka-Albert Einstein wokuhlobana okukhethekile, okusho ukuthi isikhathi siyashesha noma siyehla kuye ngejubane lapho into ihamba khona.
Ngokususelwa kulowo mbono, uma umuntu ebesemkhathini ohamba eduze kwejubane lokukhanya, isikhathi besizodlula kancane kubo kunasemuntwini osele eMhlabeni. Ngokuyinhloko, i-astronaut yayingakwazi ukuzungeza isikhala isikhathi esingaphansi kwesonto, futhi lapho bebuyela eMhlabeni, bekuzodlula iminyaka eyi-10 kubantu ababashiyile ngemuva, okwenza kubonakale ku-astronaut sengathi bangahamba isikhathi ikusasa.
Kepha yize ososayensi abaningi bekwamukela ukuthi ukweqa phambili ngesikhathi ngaleyo ndlela kungenzeka, isikhathi sokuya kokwedlule kungenye inkinga ephelele - kanti uMallett oyedwa ucabanga ukuthi angaxazulula esebenzisa ama-lasers.
Njengoba i-astrophysicist ichaze i-CNN, umbono wakhe womshini wesikhathi uxhomeke kwenye inkolelo-mbono ka-Einstein, umbono ojwayelekile wokuhlobana. Ngokwalo mbono, izinto ezinkulu zigobisa isikhathi sesikhala - umthelela esiwubona njengamandla adonsela phansi - futhi amandla adonsela phansi anamandla, isikhathi sihamba kancane.
"Uma ukwazi ukugoba isikhala, kungenzeka ukuthi ujije isikhala," UMallett utshele i-CNN. "Emcabangweni ka-Einstein, esikubiza ngokuthi isikhala kuhlanganisa nesikhathi - yingakho kubizwa ngokuthi i-space-time, noma ngabe yini oyenzayo ukwenza isikhala nayo iyenzeka ngesikhathi."
Ukholelwa ukuthi kungenzeka ukuthi ngokwesayensi kungenzeka kusontwe isikhathi sibe yinto evumela ukuhamba kwesikhathi kudlule. Uze wakha isibonelo esikhombisa ukuthi ama-lasers angasiza kanjani ukufeza le nhloso.
"Ngokutadisha uhlobo lwenkambu yamandla adonsela phansi ebikhiqizwa nge-laser ring," UMallett utshele i-CNN, "Lokhu kungaholela endleleni entsha yokubheka ukuthi kungenzeka yini ukuthi kube nomshini wesikhathi osuselwa emthini wokukhanya ojikelezayo."
Njengoba ethembile uMallet ngomsebenzi wakhe, nokho, ontanga yakhe bayangabaza ukuthi usendleleni yomshini wesikhathi osebenzayo.
"Angicabangi ukuthi umsebenzi wakhe uzoba nezithelo," isazi sezinkanyezi uPaul Sutter utshele i-CNN, "Ngoba ngicabanga ukuthi kunamaphutha ajulile ezibalweni nakwimbono yakhe, ngakho-ke into ebonakalayo ingafinyeleleka."
Ngisho noMallet uyavuma ukuthi umbono wakhe ungowokucabanga ngokuphelele kuleli phuzu. Futhi ukuthi noma ngabe umshini wakhe wesikhathi usebenza, uyavuma, kuzoba nomkhawulo onzima ongavimba noma ngubani ukuthi, athi, abuyele emuva ngesikhathi sokubulala usana u-Adolf Hitler.
"Ungathumela imininingwane futhi," utshele i-CNN, "Kodwa ungawuthumela kuphela lapho uvula khona umshini."
