Isazi sefiziksi esidumile uMichio Kaku ukholelwa ukuthi iminyaka eyi-100 ezayo izonquma isiphetho sethu njengempucuko. Ingabe sizohlala siyimpucuko yoHlobo lwe-0 noma sithuthukele ezinkanyezini?
Isikali se-Kardashev, esahlongozwa isazi sezinkanyezi saseSoviet u-Nikolai Kardashev ngo-1964 futhi saqanjwa ngaye, silinganisa intuthuko yezobuchwepheshe yempucuko ngokusekelwe ezinsizeni zayo zamandla. Inezigaba ezintathu eziyisisekelo: Uhlobo I, II, no-III. Kodwa kukhona nezimpucuko zoHlobo IV noHlobo lwe-V.
Impucuko yoHlobo I ingasebenzisa wonke amandla avela kunkanyezi engumakhelwane ukuze ihlangabezane nezidingo zayo ezikhulayo zabantu. Kuzodingeka sithuthukise ukukhiqizwa kwethu kwamandla izikhathi ezingaphezu kuka-100,000 ukuze sifinyelele kuleli zinga. Ngala mandla, sasikwazi ukulawula amandla emvelo njengezintaba-mlilo nokuzamazama komhlaba.
Impucuko yoHlobo lwesi-II ingasebenzisa amandla ayo yonke inkanyezi. Enye indlela ehlongozwayo i-Dyson Sphere, isakhiwo esithatha wonke amandla enkanyezi. Ngala mandla angaka, akukho lutho olwaziwa yisayensi olungaqeda impucuko yoHlobo Lwesibili.
Impucuko yoHlobo lwe-III iba umgadli we-galactic, enolwazi lwayo yonke into mayelana namandla. Abantu kule mpucuko bangase babe ama-cyborgs, abantu abavamile babonakale njengabaphansi. Bazoba namakholomu amarobhothi aziphindaphindayo ahlanganisa izinkanyezi futhi akhe i-Dyson Spheres. Kodwa-ke, zizonqunyelwa imithetho ye-physics, njengokuhamba ngesivinini esilula. U-Kardashev wayekholelwa ukuthi Uhlobo lwe-III lwaluyizinga lanoma yiziphi izinhlobo zezilwane, kodwa abanye bakholelwa ukuthi kungase kube nentuthuko eyengeziwe.
Impucuko yoHlobo IV ingacishe isebenzise amandla akhona endaweni yonke. Bangasebenzisa imithombo yamandla engaziwa futhi basebenzise imithetho engaziwa njengamanje ye-physics. Le mpucuko ibiyofana nonkulunkulu, inekhono lokusebenzisa indawo yonke.
Uhlobo lwezimpucuko lwe-V luwushintsho olukhulu lwamandla. Le mpucuko ecatshangelwayo ayiyona nje i-galactic noma yendawo yonke kodwa ihlukahlukene, okusho ukuthi inamandla okuhlanganisa futhi ilawule indaba yamandla kanye nemithetho yendawo yonke noma izilinganiso eziningi. Ubuchwepheshe bayo bungahlukaniswa kusukela kumlingo kuye empucukweni ethuthuke kancane. Banolwazi lokusebenzisa yonke into ngendlela abathanda ngayo. Impucuko yohlobo lwe-V ingase ikwazi ukudala noma ukucekela phansi indawo yonke ngokuthanda kwayo iguqule okungaguquki okuyisisekelo kwefiziksi ngisho nokukhohlisa okungokoqobo ngezindlela esingakwazi ukuziqonda njengamanje. Kodwa-ke, njengoba ukuqonda kwethu ithiyori ehlukahlukene kanye nobukhulu obuphakeme kusesezigabeni zakho zokuqala, le mibono ihlala iwukucatshangelwa nje, kodwa akwenzeki.
Ososayensi bathi, nakuba abantu bekude nokufinyelela kuleli zinga, akunakwenzeka uma sinakekela uMhlaba, sicisha impi, futhi sisekela intuthuko yesayensi.
Ikusasa lempucuko ligcwele izimanga nelukuluku. Ngabe ngolunye usuku sizoba uhlobo lwe-IV noma impucuko yoHlobo lwe-V? Amathuba awapheli uma siqhubeka nokulwela ulwazi nenqubekela phambili. Futhi umbuzo wokugcina: Ingabe uhlobo lwe-IV noma uhlobo lwe-V lwempucuko isivele isigqolozele kusukela ekuqaleni? Ingabe lokho okubizwa ngokuthi “I-Big Bang” kwakuwukubonakaliswa nje kwamandla abo okudala angenakwenzeka?
