Umbuzo wokuthi kunomshini wesikhathi, unesithakazelo esikhulu. Impendulo yalo mbuzo incike kakhulu kulokho okushiwo amazwi "umshini wesikhathi" nokuthi "ukhona."
Futhi eqinisweni, ikhona, ikhona futhi iyoba khona - empeleni, into efanayo, uma umshini wesikhathi ukhona ngempela. Phela, isikhathi siphelelwa yisikhathi sokuthi asiyi-nonlinear. Izinkolelo ezinjalo zikhona. Isibonelo, uSeth Lloyd wakwazi ukulungisa ijika elivaliwe ngendlela yokuthi isikhundla se-photon kuso asidluliswanga esikhala, kepha ngokuhamba kwesikhathi. Futhi lokhu kusho ukuthi, okungenani, ulwazi "umshini wesikhathi" lukhona.
Wathini u-Einstein?
Yena, njengoba wazi, wadala inkolelo yokuxhumana . Ngokwale mbono, kubonakala sengathi umbuzo wokuthi ngabe kukhona yini umshini wesikhathi okufanele unqunywe ukuze uqinisekise ukuthi kungenzeka ukuba khona empilweni yangempela, hhayi emvelweni ka Wells.
Futhi u-Einstein wayebheka isikhathi hhayi njengento ethize, kodwa njengengxenye yesine yesikhala. Kulula nje, lokhu kusho ukuthi kukhona "isivinini sesine-ntathu" sento, futhi into engeyona ehambayo (ekuphumuleni), ilingana nesivinini sokukhanya. Kodwa uma le nto ishukumisela, inani lemikhawulo yalo (ezintathu-ntathu kanye ne-four-dimensional) namanje lilingana nesivinini sokukhanya, okusho ukuthi ngokushesha into ehamba esikhaleni, ihamba kancane ngokuhamba kwesikhathi. Futhi uma le velocity ezintathu-dimensional isondela isivinini sokukhanya, ke isivinini sesikhathi sondela zero. Lona umphumela odumile wesikhathi sokuphumula, abalobi bezesayensi bezinkolelo abathanda ukukhuluma ngazo. Awu, mayelana nokuthi izimboni ze-cosmonauts ezabuya kanjani ezindiza zazingaboni ubuso obujwayelekile: ontanga yabo sebefile kakade ngokuguga . Akuyona umshini wesikhathi?
"Izibopho" kanye "nezibungu"
Futhi u-Einstein wathola ukuthi isikhathi sincike ekuvuthweni komzimba: eduze kwemizimba emikhulu igeleza kancane kancane. Ngakho-ke, ngandlela-thile ukuhlanekezela isikhala, njengoba nje amandla adonsela phansi, ungakha "izimbobo" kulo. Khona-ke, ngaphansi kwezimo ezithile, kuzokwenzeka ukuphula ubuhlobo bokususa futhi uphume "emgodini" ngaphambi kokuya lapho. Futhi lokhu kuyingozi. Lapha kuphela u-Einstein
Omunye umzamo wokuqonda ukuthi kunomshini wesikhathi, uxhumeke emigodini emnyama kanye nenganekwane noma ngokoqobo, akucaci nakancane. Kunoma yikuphi, kukholelwa ukuthi iziqhwaga, ezifa, zicindezelekile. Kodwa lolu daba aluhambanga noma yikuphi, kodwa luphenduka into encane, kodwa luyingcosana efanayo. Okusho ukuthi amandla amakhulu anjalo ankulu kakhulu. Ngokusobala, endaweni ethile lapha futhi kufanele ibe isikhala esiphezulu, ukuvumela ukuba kube khona isikhathi, kepha lokhu akukwenzeki. Kusengenakukwazi ukusebenzisa ngokunjalo "umshini wesikhathi" esinjalo: ngaphambi kokuba ufinyelele emgodini omnyama, umuntu uzohlakazeka ngaphansi kwethonya lokuvotela okukhulu emakhamukheni.
