Ngexesha lokuthetha ikude kangakanani ialpha centaur emhlabeni Kufuneka sithathele ingqalelo into yokuba xa sithetha ngeekhilomitha, kufuneka senze izibalo kakuhle kakhulu, njengoko unyaka olula umalunga ne-9.461.000.000.000 km, ukuphinda-phinda ngo-4,36 kuya kunika isixa esingama-41.249.960.000.000 km kwaye oku kuya kuba yindlela uhambo lwakho oluya kuba ngayo thabatha.
Ikude kangakanani iAlpha Centaur ukusuka eMhlabeni?
Phambi kokuba ukhankanye ukuba ikude kangakanani na le alpha centaur emhlabeni, kubalulekile ukuqaphela ukuba le nxalenye yecosmos ingaphezulu kwe inkqubo yeenkwenkwezi ezintathu o Amakroza, ethi ngokwezifundo ezahlukeneyo yeyona ikufutshane kwisixokelelwano sethu selanga kuba ikude iminyaka eyi-4.22 yokukhanya. Kolu landelelwano lwezimvo, olu seti lweenkwenkwezi ngokulandelelanayo lwenziwe ngooalphas ababini abangakumbi, oko kukuthi, ialpha centauri A no-B, ezikumgama weminyaka yokukhanya eyi-4,36.
Uhambo oluya eAlpha Centauri
Sele sisazi ukuba kukho inkwenkwezi enye ubuncinane Alpha Centauri, eyona nkwenkwezi ikufutshane eLangeni Kwaye, kuthathelwa ingqalelo ukuba iAlpha Centauri yifomula eneneni yenziwe ziinkwenkwezi ezintathu kusenokwenzeka ukuba zininzi ngakumbi. Ekubeni sabona iindaba zokufunyanwa, abaninzi baye bazibuza ukuba kuya kuthatha ixesha elingakanani ukuya eAlpha Centauri ukuze sizibonele ihlabathi elitsha.
Umboniso womzobi ka-Alpha Centauri Bb
Ikude kangakanani i-alpha centaur emhlabeni kwaye yeyiphi enye ekhoyo ikufutshane kwisixokelelwano selanga kunokuthiwa ithatha iminyaka engamashumi amabini okanye engamashumi amathathu. Ixesha elide, ewe, kodwa ngaphantsi kobomi obuqhelekileyo bawo nawuphi na umntu. Ukuhamba emajukujukwini ngenene kunzima, uhambo olulolwalo kwiindidi ezivele zavela ngokwenene. Nangona kunjalo, makhe sihlalutye ukhetho oluluncedo ngakumbi ngokuzola.
Umphezulu wendawo
Eyona nto i-vertiginous yabantu esiye sayikhupha ngaphandle ISistema Solar yiVoyager 1. Olu phononongo lubekekileyo luhambela kude eLangeni ngesantya esiyi-17,4 km/s, okanye malunga ne-540 yezigidi zeekhilomitha ngonyaka. Kodwa i-Alpha Centauri i-4,37 yeminyaka yokukhanya-okanye iiyunithi ze-272 zezulu, idijithi evelisa iminyaka eyi-000 yokukhanya kwimeko yentombazana yaseProxima Centauri. Ngesi santya, iVoyager 4,24 iya kuba malunga neminyaka engama-1 ngasemva ekufikeleleni kwi-Alpha Centauri, ucinga ukuba yahamba isiya kuyo. Ngokungathandabuzekiyo, iVoyager ayisiyonto ifanelekileyo yeenkwenkwezi.
Ngetekhnoloji esebenzisekayo inokubanakho ukuthumela isiphekepheke ngaphandle kweSolar System ngokuphindwe kahlanu ukuya kalishumi ukukhanya kuneVoyager 1. Inzulu eveziweyo ye NASA ukulungisa 'i-interstellar' probes ezikwaziyo ukusebenza i-Oort Cloud okanye i-heliopause, ulumkisa ngokufikelela kuhambo lwe-150 yezigidi zeekhilomitha kwiminyaka elishumi elinesihlanu okanye amashumi amathathu. Ewe, kubonakala ngathi siyaphumelela, de siqonde ukuba lo mgama awufikeleli kwi-000% yonyaka wokukhanya. Silandela ngokufanayo nokwaluka.
Ukufika eAlpha Centauri ngexesha elinyamezelekayo, isantya ekufuneka sifikelele kuso kufuneka sibe ngamawaka alishumi eekhilomitha ngomzuzwana. Ngeso santya siza kufikelela kwiminyaka eli-130, nto leyo enokubangela ukucaphuka okanye okunye xa siqwalasela umkhwa uninzi lwethu olunawo wokufa ngaphambi kokuba neminyaka eli-100 ubudala. Ukuba sihamba nge-25.000 km/s, ixesha lokuhamba ngenqwelomoya lixhomekeke kwiminyaka eyi-50.
Isiqingatha senkulungwane ayibi kuhambo isithuba, ngoko ke oku kufanele kube sisantya ekufuneka sisiqwalasele xa siphumelela, ngumngeni omkhulu ukuba siqhubela phambili iVoyager 1 ibhobhoza ngaphantsi kwe-18 km/s.
Kucacile ukuba asinayo enye imbuyekezo ngaphandle kokusebenzisa ii-impulse systems ezahlukeneyo kuneziqhelekileyo, ngoko ke kungcono silibale malunga nokuphehlelelwa kweekhemikhali ezisetyenziswa ziiprojectiles eziqhelekileyo. Ngoba? Ewe, ukuba sifuna ukufikelela kwi-1% yesantya sokukhanya (3000 km/s) sisebenzisa iirokethi zekhemikhali ekuvunyelwene ngazo, siya kufuna i-1026 kg enokutsha ngekhilogram nganye yobunzima benqanawa. Ngamanye amazwi, loo nqanawa yayiza kugqiba ukuba namaxesha angama-100 ubunzima boMhlaba.
Ngolunye ulungelelwaniso lwezimvo, ukuba sifuna ukuya eAlpha Centauri kule nkulungwane kufuneka senze ucamagushelo oluthile. Umzekelo, shiya ngaphandle iinqanawa eziqhutywayo. Iiprobe zoomatshini ziya kuba sezantsi kakhulu kwaye zibe nzima. Kwangaxeshanye, sinokuba nomfanekiso ngqondweni wothumo oluphelele ekugqithiseni ialpha centaur ngaphandle kobunzima bokubeka kunye nokungena kwi-orbit kufuphi nenye yeenkwenkwezi ezimbini zokuqala, ezinokuthi ziqikelele ukusetyenziswa okunamandla okugqithisileyo.
Inyukliya eshushu kunye nokuqaliswa kwe-ionic
I-thrust yombane - ionic okanye iplasma - okwangoku isetyenziswa kwiziphekepheke ezininzi kwaye iyakwazi ukuphumeza ukuqhutywa okuthile kwemizuzwana emininzi. Ukuqaliswa kwe-atomic thermal kulandela kancinci ngasemva. Ezi nkqubo zokuqhuba azimbi kwaphela ukukhwela zijikeleze ISistema Solar, kodwa bekuya kusithatha iminyaka emalunga nama-40.000 ukufikelela kwi-Alpha Centauri.
iiseyile zelanga
Apha siqala ukuhamba kwindawo ekhangayo. Iseyile yelanga ekubonakalisweni kweendiza zasezulwini. Ngaloo ndlela, oku akunjalo ikhandlela elilula iifotonics njengee-Ikaros zaseJapan. Isichazi 'solar' sinesizathu. Iseyile yelanga isekwe kunikezelo oloyikekayo kunye nokumelwa kweeparachute ezithi, njengeseyile yefotonic, isebenzise ukunyanzeliswa kwemitha yokukhanya kwelanga-kwaye ingeyiyo leyo yomoya welanga njengoko ngamanye amaxesha inyibilika ngempazamo- ukukhawulezisa isiphekepheke ukuba sihambe kwangoko. ukusuka kwiSolar System. Kodwa ukusebenzisa le nkqubo kuyimfuneko ukwandisa iseyile ekufutshane yeLanga.
Kwelinye icala, sicinga ukuba kumashumi eminyaka ezayo sinobuchule bokwakha iiseyile ezinkulu ezilula kakhulu ezikwaziyo ukumelana nokukhawuleza okungaphezulu kwe-60 g kunye namawakawaka eeCelsius, iseyile yelanga inokuhamba iye kuthi ga ngoku. ialpha centaur kwiwaka okanye amawaka amabini eminyaka. Kusenzeka kakhulu, kodwa le nkqubo inokudityaniswa nezinye ukunciphisa ixesha lokubhabha.
Ukuqaliswa kweNyukliya ngothotho lwee-pulses
Ivunyiwe iprojekthi ye-orion Ukususela kwiminyaka yoo-60, le nkqubo ibonakala iphambene, kodwa inyaniso kukuba iiseti ezidityanisiweyo zobuchule sele zivavanyiwe. Inqanawa yenyukliya eshukumayo ishukuma ijikeleza ukudubula kwezinto zakudala zeathom kumgama omfutshane ukusuka kwisithuthi. I-vehement wave ifakwe kwipleyiti ethile ene-spirals, ehambisa inxalenye yamandla kwinqanawa ngendlela yokuba isantya ngokukhawuleza. I-Orion yayisisithuthi esithembisayo sokuhamba sijikeleza iSolar System, kodwa kukhenketho lwasemajukujukwini le nkqubo ayihendeki kangako.
Ngolu landelelwano lwezimvo, umsebenzi owenziwayo ubaluleke ngokwenene kuba ngale ndlela kukho unxibelelwano olukhulu kunye noko kuya kuba njalo. umgama phakathi kwealpha centauri kunye nesijikelezi-langa sethu.
Okokugqibela, kubalulekile ukuqaphela ukuba lo mgama ungakanani na le alpha centaur ukusuka emhlabeni esiya kucinga ngawo malunga neminyaka yokukhanya njengoko kukhankanyiwe ngasentla, ukongeza kwinto yokuba kukho iindidi ngeendidi zemilinganiselo eziya kuba nexesha elide ukufikelela kuzo. iseti yethu ye iinkwenkwezi ekufutshane, ukuchaneka ngakumbi, malunga neminyaka eyi-150 ukufikelela kwi-Alpha Centauri. Ayisiyonto imbi kwinqanawa yokwahlulahlula, kodwa ayibonakali ifaneleke kakhulu kumsebenzi otyhilayo ngokwenene kwaye onentsingiselo yenkolelo ezenzekelayo kwabo bafayo (ingathethi ngokoqobo) ukwazi imimangaliso ekufuphi yenkqubo yethu yelanga kwaye ke ngoko, yomhlaba wethu.
