Metagalaxy - it ... Inkcazo kunye nesakhiwo metagalaxy

Iinkwenkwezi azisasazwa babeziindleko iphela lazo. Bona zidityanisiwe ngokwamaqela, ezibizwa yiminyele. Nangona kunjalo, kuba yimpazamo ukucinga ukuba namakroza zibonakale elundini - a ezisebenzisanayo star. Ezo zibane ukuthi uyabona kwenye indawo zezulu, enyanisweni, akunakuba nako kwahlulwa omnye komnye kwi kumgama enkulu.

Ukuchazwa endaweni yonke

Ngokutsho isichazi-magama ngeenkwenkwezi, metagalaxy - ukuba yinxalenye indalo yonke, leyo ilandelwe zaphandwa ngoncedo iindlela zenzululwazi zale mihla kunye nezixhobo. Oku malunga neebhiliyoni iinkqubo elanga. Kukho nenye inkcazelo. Umzekelo, kwi-Great Soviet Encyclopedia ithi metagalaxy - ingqokelela leminyele, esiquka okuninzi leminyele (1 billion), nto leyo ziqwalaselwe kusetyenziswa yerediyo. Namandla kakhulu uba ubugcisa bale mihla, kokukhona kwandiswa imida ulwazi lwabantu indalo engaziwayo. Umba wendalo iphela nto eyenza sonke metagalaxy. Ngamanye amaxesha ungabona le nkcazelo ilandelayo: indalo kunye metagalaxy - kuyahambisana.

Ingqiqo ka "metagalaxy" yaye "yonke ebonakalayo"

Ukuze ufumane inkcazelo engakumbi malunga yintoni metagalaxy, ukuchazela omnye gama - "yonke ebonakalayo". Izazi bathi eli binzana ukuba yinxalenye iphela, apho umntu ebona Earth. Kwangaxeshanye, oosonzululwazi nga bagcine kwaye bahlole ezahlukeneyo iinxalenye zayo - akukho kuphela iinkwenkwezi nezinye izijikelezi, kodwa amaza kunye imiyalezo - konke uyaqhubeka ikhaya lethu kwindalo iphela. Yonke ebonakalayo yinxalenye kuphela kwendawo yonke omkhulu. It has yomda wayo - elundini khozimologi.Sonke. Izazinzulu zikholelwa ukuba inani elipheleleyo ezisebenzisanayo inkwenkwezi wendalo obonakalayo idlula 170 billion.

Ekubeni ukufundisa le yonke ebonakalayo kuquka inani elikhulu lezinto kunokuba kuyenzeka ukubona umntu oqhelekileyo, yaqalisa ingqiqo metagalaxy. Stars ziwe, yabonakala ngoncedo ngobugcisa jikelele, ngezoqoqosho, ziyinxalenye obonakalayo. Ukuba, ke, uthetha izinto ezingaphaya ukufikelela kumda, ezi zinto kuthiwa Metagalactic. Izazi abaninzi bakholelwa ukuba ubungakanani ngqo iphela iphezulu kakhulu kunaleyo anokuthi babonwe.

Kodwa yonke ebonakalayo ayikwazi nibonwe izazi ngokupheleleyo, kuba zimiselwe radiation ethile. Ngenxa yokuba phantse akunakwenzeka ukuba bagcine oko kungaphaya kolundi. Le radiation - into zikude apho "yenza" ngeenkwenkwezi zale mihla.

izihloko galaxy

Iminyele iqundaniswe ezisebenzisanayo neendidi ezahlukeneyo ngendlela efanayo njengoko kwenza iinkwenkwezi. Kukho iindidi ezimbini ezisebenzisanayo Way - globular aze asasazeke. Zonke iinkwenkwezi ukuze sibonwe ngeliso lenyama okanye ngokusebenzisa yerediyo (hayi eyona inamandla kwabo), uhlobo inkqubo enye - loo Way. Izazinzulu zikholelwa ukuba kukho amacandelo malunga 100 ezigidi.

Ukufunyanwa leminyele ezintsha

Ngaphaya kwemida Milky Way, izazi baye bafumanisa inani elikhulu ezinye iinkqubo nkwenkwezi. afane zethu kubume bayo. Ngokufanayo, ukuba zenziwe ezigidi iinkwenkwezi, ezinye ezo efana nelanga. isakhiwo Metagalaxy kuye sasingumba uphando Ekuveleni XIX kunye XX eminyaka. Emva koko, ezinye izazi beyiseka ukuba mafu okunene inkwenkwezi iinkqubo, leyo iyasuswa iMilky Way ezigidi ukukhanya iminyaka.

Andromeda Galaxy - umzekelo inkqubo star elizimeleyo

Ngenkulungwane XX ekuqaleni, uEdwin Hubble singqiniwe ukuba ezi mafu ngokwenene ezahlukeneyo, ngokufuthi zobukhulu enkulu, iinkqubo inkwenkwezi. Umzekelo kwingqumba ekwanti loo Sisihloko leenkwenkwezi Andromeda. Wati kungaba ebusuku ecacileyo, kodwa kumnyama. It ibonakala njenge zazingacacanga eliqaqambileyo suntswana ubungakanani disk kwenyanga. Ngeendlela ezininzi, kumnyele efana iMilky Way. It iyabonakala ukuba mkhanya utyekelo kancinane ngokunxulumene abone ngayo. Inxalenye ezigqame yayo yakhiwe yi uhlobo ephotheneyo, yaye waba ngaphezu kumnyele wethu. Andromeda Nebula uvela kuthi kumgama ukukhanya-kweminyaka ngaphezu kwesigidi esi-1.

Imfundiso iphela elandayo

Lo mbono ngomnye yesayensi mkhulu. amanye amagama ayo - 'imfundiso le metagalaxy elandayo ", okanye nje The Big Bang Theory. isikhundla sayo ezisisiseko kukuba indalo wazalwa malunga 20 bhiliyoni kwiminyaka eyadlulayo. Oku kungenxa kukuqhushumba ihlwili ingxinano elikhulu enkulu zenkqunto. Njani le ngcamango? Kanye ngaphambi kokuba ithandwa-ekuthiwa imodeli isotropic womhlaba. Umbhali we omnye wabo Albert Einstein.

ntoni eli gama lithetha ntoni? Way nganye (kunye metagalaxy) lungohlulwa lube kwimimandla eziliqela sabaqalayo. Kunjalo kungenziwa yonke indalo. Isotropy kuthetha ukuba iipropati metagalaxy ziyafana kuzo zonke iindawo. Ngokutsho imodeli esiphakanyiswa Einstein, metagalaxy - inkqubo emileyo apho akukho tshintsho. Kwixa elizayo, lo lethiyori, wawancamisa ekuhleni zizazinzulu Russian A. A. Fridmanom. Wacela umfuziselo iphela elandayo.

Quasars - izinto ziqaqamba kwi Universe

Ngumrhumo obalulekileyo isifundo bezinto ezahlukeneyo metagalaxy unika isifundo quasars - Iziseko engaqhelekanga nezinomtsalane ezintle. Quasars zibangelwa imingxuma ezingaziwayo abamnyama, elubengezelo kwaso ke Asinakwaphula eselumelwaneni Way. Quasar yokunikana, izigidi amaxesha ngokukhawulezisa ubunzima elanga.

Xa oosonzululwazi kuqala got ulwazi malunga quasars, babengenako ukukholwa khona zabo. Healthy kugxeka umnqweno wabakhokelela ukufumana ingcaciso ngonzululwazi sokuba ezi zinto. Nakuba kunjalo, izifundo ngeenkwenkwezi emva aye abonisa ukuba izazinzulu eneneni yeyona ocacileyo ifomu metagalaxy. imingxunya omkhulukazi abamnyama imithombo best sesondlo quasars. imingxunya Black yale hlobo - iindawo indawo apho amandla omxhuzulane lomelele kangangokuba kwelanga akakwazi kwaphula aphume emideni yabo. imingxunya omkhulukazi amnyama nazo imfihlelo ukuba izazi. ubukhulu yabo ibe ukuya kubukhulu kwenkqubo elanga. ukuba enzeka njani ke, akukho inzululwazi Akukabonakali ukuqonda.
