Incinci ngaphezulu kweminyaka elikhulu eyadlulayo Akukho namnye kwiplanethi yethu eyaziyo ukuba indalo iyanda. Kodwa nangona zonke iingxaki kunye ne-chativeties kangangokuba inkulungwane yamashumi amabini zazizisa uluntu, yile nkulungwane iphawulwe yinkqubela phambili yesayensi nezobuchwephesha. Ngexesha elifutshane elincinci, safunda ngehlabathi nendalo iphela kunangaphambili. Imbono yokuba indalo yethu yanda kule minyaka idlulileyo idlulileyo 13.8 Iminyaka yokuqala ye-Telgian Widerist George Geter Geters ngo-1927. Kwiminyaka emibini kamva, iAmerican Astronoma Edwina hubble ikwazile ukuqinisekisa ukuba le hypothesis. Wafumanisa ukuba wonke umntu osuka kuthi uphela uyashenxiswa kuthi kwaye yintoni enye, ngokukhawuleza kwenzeka. Namhlanje zininzi iindlela ezinokuthi ziqonde ukuba indalo yethu inyuka njani ngobukhulu. Nazi nje amanani nje abaphandi abafumaneka kwinkqubo yokulinganisa, ixesha ngalinye bafunyanwa ngokwahlukileyo. Kodwa kutheni?
Eyona mfihlakalo inkulu yendalo iphela
Njengoko sisazi namhlanje, kukho ubudlelwane obusondeleyo phakathi komgama ukuya kwi-galaxy kwaye isuswa ngokukhawuleza kangakanani. Ke ngoko masithi, i-galaxy kumgama we-1 megapardes kwiPlanethi yethu (i-megaparsk imalunga ne-3.3 yezigidi zeminyaka) isuswe ngesantya sama-70 ngekota. Kwaye igalari okwethutyana, kumgama obini Megaparsk, ihamba kabini ngokukhawuleza (i-140 km / s).
Okubangela umdla kukuba, namhlanje kukho iindlela ezimbini eziphambili zokuchonga ubudala bendalo okanye, kwinzululwazi, isiqendu sezenzululwazi. Umahluko phakathi kwala maqela mabini kukuba iseti enye yeendlela ithathela ingqalelo izinto ezisondeleyo kwindalo iphela, kwaye enye ikwindawo ekude kakhulu. Nangona kunjalo, akunandaba nokuba izazinzulu zingasebenzisi ithuba lendlela, iziphumo zihlukile ngalo lonke ixesha. Iphuma, okanye senze into engalunganga, okanye kwenye indawo kwindalo iphela kukho into engaziwayo ngokupheleleyo.
Kwisifundo esisandula ukupapashwa kwi-Airxiv.org Server iseva, izazi ngeenkwenkwezi, isebenzise indlela ye-smart yokulinganisa ukwandiswa kwendalo ebizwa ngokuba yi-sublocations yokukhanya komhlaba Eli ligama le-barrarre, kodwa kubandakanya umbono ongempela.
Ngaba ufuna ukuhlala nazi iindaba zamva nje kwiLizwe lezeNzululwazi neTekhnoloji ephezulu? Bhalisa kwisitishi sethu seendaba kwi-telegraph ukuba ungaphoswa nantoni na enomdla!
Khawufane ucinge ukuba ume kumda wehlathi, kanye phambi komthi. Kuba usondele kakhulu, ubona umthi omnye kuphela kwinkalo yakho. Kodwa kufanelekile ukugungxula, njengoko imithi emininzi iya kuvela phambi kwamehlo akho. Kwaye uyakuhamba ngoku, imithi oza kubona. Malunga nento enye yenzekayo neminyele i-galaxies ukuba izaziswa ziqwalaselwa ngoncedo lweeteleskopu, kunzima ngakumbi.
Ungalufumana njani isantya sokwanda kwendalo?
Ukufumana izibalo ezilungileyo, izazi ngeenkwenkwezi zibukele iGalaxis, ezisondeleyo emhlabeni, malunga neminyaka engama-300 yezigidi ezingama-300, kwaye isondele. Nangona kunjalo, ukubukela i-galaxies, kuyimfuneko ukuba uthathele ingqalelo uthuli, i-galaxies yeGalaries kunye neqela leenkwenkwezi, elinokubonwa kwimifanekiso efunyenweyo kusetyenziswa iteleskopu.
Kuyathakazelisa: Iza kukhangela njani amandla amnyama?
Indalo iphela schitra. Ukusukela ngonyaka we-1990s, izazi ngeenkwenkwezi zibonile ukuba iinkwenkwezi ezikhoyo kakhulu zisoloko zikhona, ebonisa imilinganiselo elula. Oku kwabakhokelela kwimbono yokuba indalo ngoku yandisa ngokukhawuleza kunangaphambili, ethi, ikhokelele ekufumanekeni kwamandla amnyama - amandla amnandi, akhawulezisa ukwanda kwendalo.
Njengababhali bomsebenzi wesayensi babhala, xa sijonga izinto ezikude kakhulu, sibabona njengangaphambili xa indalo incinci. Ukuba isantya sokwandiswa kwendalo emva koko sahlukile (sithi, 12-13, iminyaka eyi-8 yebhiliyoni kwiminyaka eyadlulayo), singaphantsi kwewaka lezigidi kwiminyaka eyadlulayo), sinokufumana amaxabiso amabini ahlukeneyo kwi-hubble engaqhelekanga. Okanye ngaba iindawo ezahlukeneyo zendalo ikhula ngesantya esahlukileyo?
Funda kwakhona: Yintoni eyaziwa ngayo abantu malunga nobudala kunye nokwandiswa kwendalo?
Kodwa ukuba inqanaba lokwandiswa litshintshile, lithetha ubudala bendalo yethu ayikho kwaphela njengoko sicinga ukuba (izazinzulu zisebenzisa ireyithi yokwandiswa kwendalo). Oku, kuthetha ukuba indalo inobungakanani ohlukileyo, okuthetha ixesha elifunekayo lwenzekile, iya kwahluka.
Ngayiphi na imeko, i-hubble engapheliyo ngumxholo weembambano ezishushu kwindawo yeenkwenkwezi. Kuba isifundo esitsha songeze imibuzo emininzi, umlo wokuvumelana nokungaqiniseki kuya kuba kudala. Ngenye imini, ewe, ukuqonda kwethu isithuba kuya kutshintsha. Kodwa xa oku kusenzeka, i-cossologists kuya kufuneka ijonge enye into, yintoni enokuphikisana. Ngokuqinisekileyo baya kwenza ntoni.
