Ithiyori ye-Wormhole kanye ne-Spacetime
Ezincwadini zesayensi kanye nesayensi eqanjiwe, ama-wormhole angumqondo oye wadonsa umcabango womuntu. Umqondo wokuthi amaphuzu amabili ahlukene esikhaleni-sesikhathini angaxhunyaniswa yindlela efihliwe, okuvumela ukuhamba okusheshayo kunokukhanya, uvuse ukuqagela mayelana nokwenzeka kokuhamba phakathi kwezinkanyezi kanye nokuhamba kwesikhathi. Ukuqonda kwethu ama-wormhole kuthonywe kakhulu yinkolelo-mbono ka-Albert Einstein yokuhlobana okujwayelekile, kanye namamodeli ahlukahlukene enkolelo-mbono aphakanyisiwe kusukela ngaleso sikhathi.
Isingeniso kuMqondo weWormhole
I-wormhole iyisisombululo esisekelwe embonweni wezibalo zensimu zika-Einstein kumbono jikelele wokuhlobana. Kalula nje, i-wormhole ingacatshangwa "njengendlela emfushane" yesikhala-isikhathi evumela izinto noma ulwazi ukuthi luhambe phakathi kwamaphuzu amabili ahlukene ngokushesha kunokuba belungahamba ngesikhathi-isikhala esivamile.
Ngokwezibalo, ama-wormhole aqala ukuphakanyiswa ngo-1935 ngu-Albert Einstein noNathan Rosen, abasungula umqondo we-“Einstein-Rosen Bridge.” Bachaza i-wormhole njengebhuloho elihlanganisa “amashidi” amabili ahlukene e-space-time. Lawa ma-wormhole “anemilomo” emibili, ngalinye lixhunywe endaweni ehlukile e-space-time, kanye “nomphimbo” ohlanganisa lokhu kokubili.
Isakhiwo se-Wormhole kanye Nokuzinza
Omunye wemibuzo emikhulu mayelana nemigodi yezimbobo ukuzinza kwazo. Imbobo yezimbobo engazinzile ingawa ngokushesha ngemva kokwakheka, ivimbe izindlela zokuxhumana noma zokuhamba ebingazinikeza. Umbuzo wokuzinza uhlobene nohlobo lwezinto noma amandla akhona ngaphakathi noma eduze kwembobo yezimbobo.
Ama-wormhole, njengoba eqashelwa ezincwadini zefiziksi, adinga izinto ezinezakhiwo ezingavamile. Lezi zakhiwo ezingavamile zibhekisela ezintweni ezinamandla amabi noma ingcindezi engavamile, ngokuphambene nalokho esivame ukukubona kufiziksi yakudala. Le nto engavamile isebenza njenge-buffer, igcina imbobo ivulekile futhi ivimbele ukudilika kwayo. Uhlobo olulodwa lwezinto ezingavamile okukhulunywa ngazo ngokuvamile amandla amabi akhiqizwa umphumela weCasimir. Lo mphumela uyinto eyenzeka kufiziksi ye-quantum ekhiqiza ingcindezi engemihle ngezinga elincane.
Izinhlobo ze-Wormholes
Ngokwesakhiwo sabo kanye nezakhiwo zabo, kunezinhlobo eziningana zemibono ye-wormholes eziphakanyisiwe:
1. Imbobo ye-Schwarzschild: Mhlawumbe lena yindlela elula kakhulu ngokwemfundiso, exhumanisa imigodi emibili emnyama ye-Schwarzschild. Kodwa-ke, lolu hlobo lwembobo ye-worm aluzinzile ngoba lunganyamalala ngokushesha ngenxa yemisebe ye-Hawking futhi luzowa ngokushesha.
2. Ama-Wormhole Angadlula: Lezi yizinhlobo zama-wormhole avame ukuvela ezindabeni zesayensi, afana nalawo aku-movie ethi Interstellar. Ukuze kuhanjwe ngokuphepha, lezi zinhlobo zidinga izinto ezingavamile ukuze zigcine umphimbo we-wormhole uvulekile.
3. Imbobo yeMorris-Thorne: Yethulwa nguMichael Morris noKip Thorne ngo-1988, lo mqondo uhilela imbobo yembobo ezinzile, ekwazi ukuwela abantu enezinto ezingavamile ngaphakathi.
4. Ama-Euclidean Wormholes: Aqagela kakhulu futhi anemfundiso, lolu hlobo lungadinga ubukhulu obengeziwe ukuze lube khona, ngokusekelwe ku-string theory noma ku-M-theory.
Ukuhamba Ngesikhathi Neziphazamiso
Esinye sezici ezithakazelisa kakhulu ngama-wormhole yikhono lawo lokuhamba ngesikhathi. Uma enye yezimbobo ze-wormhole yayihamba ngesivinini esivumelanayo noma eduze nensimu enamandla kakhulu yamandla adonsela phansi, isikhathi besizohamba kancane kakhulu kulowo mnyango uma siqhathaniswa nezinye, ngenxa yemiphumela yokwandiswa kwesikhathi. Ngale ndlela, umhambi ocabangayo angangena embobo ye-wormhole futhi aphume esikhathini esidlule noma esizayo.
Kodwa-ke, ukuhamba kwesikhathi esikhathini esidlule kudala izimpikiswano ezahlukahlukene. Enye yezimpikiswano ezaziwa kakhulu yi-grandfather paradox, lapho umhambi wesikhathi ebuyela emuva esikhathini futhi abulale umkhulu wakhe ngaphambi kokuba azalwe, okudala ukuphikisana kwembangela nomphumela. Izazi zesayensi eziningi zikholelwa ukuthi imithetho ye-physics njengoba siyiqonda njengamanje ingase ingavumeli ilungiselelo elinjalo.
Imiphumela ye-Astrophysics kanye ne-Cosmology
Ama-wormhole, uma ekhona, angaba nemiphumela ebalulekile ku-astrophysics kanye ne-cosmology. Angachaza izenzakalo eziningana ezingachazeki njengamanje, njengokuxhumana phakathi kwemithala noma ukubonwa okungavamile okuzungeze imigodi emnyama. Ezinye izinkolelo-mbono zize zicabangele nokuthi ama-wormhole angasebenza njengesibonelo esivumelekile sobunye obungabonakali enkabeni yomgodi omnyama.
Ubuchwepheshe Bokuhlola Nezithiyo
Naphezu kwenkolelo-mbono ebanzi yama-wormholes, ubuchwepheshe obudingekayo ukuze kutholakale noma kudaliwe okwamanje abufinyeleleki. Ukudala noma ukulawula izinto ezingavamile ezidingekayo ukuze kuqiniswe i-wormhole kuyinselele enkulu, ingasaphathwa eyokuthi izidingo zamandla ezinkulu zingadingakala.
Ukuhlolwa okufana nama-laser interferometers okuhloswe ngawo ukuthola amagagasi adonsela phansi (njenge-LIGO) kunganikeza ubufakazi obungaqondile be-wormholes ngokubuka izenzakalo ezihambisana nokuba khona kwazo. Kodwa-ke, kuze kube yileso sikhathi, i-wormholes isalokhu iyindawo ethakazelisayo yokuqagela kwesayensi.
I-Penutup
Ithiyori ye-Wormhole inikeza umbono omusha ngesikhala nesikhathi, okusivumela ukuthi sicabangele amathuba okuhamba phakathi kwezinkanyezi ngezindlela ezingakaze zicatshangwe ngaphambili. Nakuba ukuba khona kwazo kungakaze kuqinisekiswe ngokobufakazi, ukutholakala kwezinto ezingavamile noma ubuchwepheshe obukwazi ukuzilawula kungavula iminyango emisha ekuhloleni isikhala ngesikhathi. Ngakho-ke, ucwaningo kanye nokuqagela mayelana ne-wormhole akugcini nje ngokwandisa ukuqonda kwethu indawo yonke kodwa futhi kuphefumulela imizamo eyengeziwe kwisayensi nobuchwepheshe.
Ekuphetheni, ama-wormhole aphonsela inselelo ukuqonda kwethu okuvamile kwesikhathi-sikhala futhi asunduza imingcele yomcabango wesayensi. Kungakhathaliseki ukuthi ekugcineni afakazelwe ukuthi ayizinto zangempela, umqondo wawo uyaqhubeka nokwenza kube lula izingxoxo ezicebile mayelana nohlobo lwendawo yonke yethu kanye nekusasa lokuhlola kwabantu.
