Ngesikhathi sokukhulelwa ikude kangakanani i-alpha centaur emhlabeni Kufanele sicabange ukuthi uma sikhuluma ngamakhilomitha, kumele senze izibalo kahle kakhulu, njengoba unyaka okhanyayo ulinganiselwa ku-9.461.000.000.000 km, ukuphindaphinda ngo-4,36 kuzonikeza isamba esingu-41.249.960.000.000. XNUMX km futhi lokhu kungaba yindlela uhambo lwakho olungaba ngayo. thatha.
Ikude kangakanani i-Alpha Centaur ukusuka eMhlabeni?
Ngaphambi kokusho ukuthi le alpha centaur ikude kangakanani emhlabeni, kubalulekile ukuqaphela ukuthi le ngxenye yecosmos ingaphezu kwe uhlelo lwezinkanyezi ezintathu o izinkanyezi, okuyinto ngokwezifundo ezihlukahlukene eseduze kakhulu nesimiso sethu sonozungezilanga njengoba likude ngeminyaka yokukhanya engu-4.22. Kulolu hlelo lwemibono, leli qoqo lezinkanyezi liphinde lakhiwe amanye ama-alpha amabili, okungukuthi, i-alpha centauri A no-B, aqhele ngeminyaka yokukhanya engu-4,36.
Uhambo oluya e-Alpha Centauri
Sesiyazi ukuthi okungenani kunenkanyezi eyodwa Alpha Centauri, inkanyezi eseduze kakhulu neLanga. Futhi, kucatshangelwa ukuthi i-Alpha Centauri empeleni iyifomula yakhiwe izinkanyezi ezintathu cishe kukhona abaningi abengeziwe. Njengoba sabona izindaba zokutholakala kwalokhu, abaningi baye bazibuza ukuthi kuzothatha isikhathi esingakanani ukuya e-Alpha Centauri ukuze sizibonele izwe elisha.
Okuvelayo komculi ka-Alpha Centauri Bb
Ikude kangakanani i-alpha centaur emhlabeni futhi iyiphi enye ekhona esiseduze nesimiso sonozungezilanga kungathiwa ihlala iminyaka engamashumi amabili noma amathathu. Isikhathi eside, yebo, kodwa singaphansi kwesilinganiso sempilo yanoma yimuphi umuntu. Uhambo lwasemkhathini lunzima ngempela, uhambo lwalo ngezinhlobo eziguquke ngempela. Nokho, ake sihlaziye ukukhetha okuwusizo ngokuzola.
Ummango wesikhala
Into yomuntu eqinile kakhulu esiyixoshile kuyo Uhlelo lomkhathi yiVoyager 1. Lolu phenyo oluhloniphekile lusuka eLangeni ngesivinini esingu-17,4 km/s, noma cishe amakhilomitha ayizigidi ezingu-540 ngonyaka. Kodwa i-Alpha Centauri iqhele nge-light-year engu-4,37-noma amayunithi wesibhakabhaka angu-272, idijithi ekhiqiza iminyaka engu-000 yokukhanya endabeni yentombazane yase-Proxima Centauri. Ngalesi sivinini, i-Voyager 4,24 izoba ngemuva kweminyaka engaba ngu-1 ekufinyeleleni ku-Alpha Centauri, kucatshangwa ukuthi yahamba ngakuyo. Akudingekile ukusho, i-Voyager akuyona inkanyezi efanelekile kakhulu.
Ngobuchwepheshe obusebenzisekayo kungaba amandla okuthumela umkhumbi-mkhathi ngaphandle kwe-Solar System ukukhanya okuphindwe kahlanu kuya kashumi kune-Voyager 1. The serious obala of the NASA ukulungisa ama-'interstellar' ama-probe akwazi ukusebenza i-Oort Cloud noma i-heliopause, uxwayisa ngokufinyelela uhambo lwamakhilomitha ayizigidi ezingu-150 eminyakeni eyishumi nanhlanu noma engamashumi amathathu. Hhayi-ke kubukeka sengathi siyaphumelela, size sibone ukuthi leli banga alifiki ku-000% wonyaka wokukhanya. Siphishekela okufanayo nokuthwasa.
Ukuze sifike ku-Alpha Centauri phakathi nesikhathi esibekezeleleka, izivinini okufanele sizifinyelele kufanele zibe amakhilomitha ayizinkulungwane eziyishumi ngomzuzwana. Ngaleso sivinini singafinyelela iminyaka engu-130, okungase kucabange ukucasuka okuthile noma okunye uma kucatshangelwa umkhuba iningi lethu elinawo wokufa ngaphambi kweminyaka eyi-100. Uma sihamba ku-25.000 km/s, isikhathi sokundiza singaphansi kweminyaka engu-50.
Ingxenye yekhulu ayikubi ohambweni isikhala, ngakho-ke lesi kufanele kube isivinini okufanele sisicabangele uma siphumelela, kube yinselele impela uma siqhubekisela phambili ukubhoboza kweVoyager 1 ngaphansi kuka-18 km/s.
Kuyacaca ukuthi asinaso esinye isinxephezelo ngaphandle kokusebenzisa ama-impulse systems ahlukene kunalawo ajwayelekile, ngakho-ke kungcono sikhohlwe ngokusetshenziswa kwamakhemikhali okuthiwa asetshenziswa ama-projectiles ajwayelekile. Kungani? Nokho, njengoba uma sifuna ukuzuza u-1% wejubane lokukhanya (3000 km/s) sisebenzisa amarokhethi amakhemikhali okuvunyelwene ngawo, sizodinga u-1026 kg wokuvutha ngekhilogremu ngayinye yesisindo somkhumbi. Ngamanye amazwi, lowo mkhumbi wawuzogcina unesisindo esiphindwe izikhathi eziyi-100 kunoMhlaba.
Ngolunye uhlelo lwemibono, uma sifuna ukuya e-Alpha Centauri kuleli khulu leminyaka kumele senze ukuhlawulelwa okuthile. Isibonelo, shiya ngaphandle imikhumbi eqhutshwayo. Ama-probe omshini azoba phansi kakhulu futhi abe nzima. Ngesikhathi esifanayo, singacabanga ngemishini egcina ukudlulisa i-alpha centaur ngaphandle kobunzima ukuthambisa nokungena emzileni eduze nenye yezinkanyezi ezimbili zakuqala, okungase kucabange ukusetshenziswa okunamandla ngokwedlulele.
Ukuqaliswa okushisayo kwe-nuclear ne-ionic
I-thrust kagesi - ionic noma i-plasma - okwamanje isetshenziswa kumikhumbi-mkhathi eminingana futhi ikwazi ukufeza ukuqhutshwa okuthile kwemizuzwana embalwa. Ukwethulwa kokushisa kwe-athomu kulandela ngemuva kancane. Lawa masistimu okushayela awakubi neze ukuwagibela uzungeza Uhlelo lomkhathi, kodwa kungasithatha iminyaka engaba ngu-40.000 XNUMX ukufika ku-Alpha Centauri.
amaseyili elanga
Lapha siqala ukuhamba endaweni ekhangayo. Iseyili yelanga ekukhulumeni kwezindiza zasezulwini. Ngalo mqondo, lokhu akunjalo ikhandlela elilula izithombe njengama-Ikaros aseJapane. Isichasiso 'solar' sinesizathu. Iseyili yelanga isekelwe ekusabalaliseni okwesabekayo okunomfanekiso wamapharashuthi okuthi, njengoseyili wezithombe, asebenzise ukuphoqelelwa kwemisebe yokukhanya kwelanga - hhayi lokho komoya welanga njengoba ngezinye izikhathi uncibilika ngephutha- ukusheshisa umkhumbi-mkhathi ukuthi usuke ngaphambi kwesikhathi. kusukela kuSolar System. Kodwa ukuze kusetshenziswe lolu hlelo kuyadingeka ukwelula useyili oseduze weLanga.
Ngakolunye uhlangothi, sicabanga ukuthi emashumini eminyaka ezayo sinekhono lokwakha oseyili abakhulu abalula kakhulu abakwazi ukumelana nokushesha okungaphezu kuka-60 g nezinkulungwane zama-degree Celsius, useyili welanga ungahamba ufinyelele phezulu. i-alpha centaur eminyakeni eyinkulungwane noma eyizinkulungwane ezimbili. Kusengenzeka kakhulu, kodwa le sistimu ingahlanganiswa nezinye ukuze kuncishiswe isikhathi sendiza.
Ukwethulwa kwe-nuclear ngochungechunge lwama-pulses
Igunyaziwe iphrojekthi ye-orion Kusukela ngawo-60, lolu hlelo lubonakala luhlanya, kodwa iqiniso liwukuthi amasethi ahlanganisiwe amasu asevele ahlolwe. Umkhumbi wenuzi ophephukayo uzungeza izinto zobuciko ze-athomu eziqhumayo ebangeni elifushane ukusuka emotweni. I-vehement wave icwiliswe ipuleti elithile elinezivunguvungu, elidlulisela ingxenye yamandla emkhunjini ngendlela yokuthi isheshise kancane. I-Orion bekuyimoto ethembisayo yokuhamba uzungeza I-Solar System, kodwa ohambweni lwasemkhathini lolu hlelo aluheheki kangako.
Kulolu hlelo lwemibono, umsebenzi owenziwayo ubaluleke ngempela ngoba ngale ndlela kukhona ukuxhumana okukhulu nalokho okungaba khona. ibanga phakathi kwe-alpha centauri neplanethi yethu.
Okokugcina, kubalulekile ukuqaphela ukuthi ingakanani ibanga le-alpha centaur ukusuka emhlabeni okufanele sicabange ngayo ngeminyaka yokukhanya njengoba kushiwo ngenhla, ngaphezu kweqiniso lokuthi kunezigaba ezihlukahlukene zobukhulu obuzoba nesikhathi eside ukufika. isethi yethu ye izinkanyezi eduze kakhulu, ukunemba kakhudlwana, cishe iminyaka eyi-150 ukufika ku-Alpha Centauri. Akukubi ngomkhumbi ohlukanisayo, kodwa akubonakali kuwufaneleka kakhulu umsebenzi oveza ngempela futhi onenjongo wenkolelo ezenzakalelayo kulabo abafayo (hhayi ukukhuluma ngokoqobo) ukwazi izimangaliso eziseduze zesimiso sethu sonozungezilanga futhi ngenxa yalokho, zomhlaba wethu.
