U-Edwin hubble

Iminikelo ekwandisweni kwendawo yonke yeHubble

Kule bhulogi sesivele sikhulume ngezihloko eziningi ezihlobene nesayensi yezinkanyezi. Phakathi kwabo siyathola isimiso sonozungezilanga, UMars, K Es Es Escha! Escha Escha! Escha Escha! Escha!, Venus, I-Jupiter, Saturn, njll. Kodwa-ke, asikakhulumi ngososayensi abathuthukise le sayensi ngenxa yokutholwa kwabo. Ngakho-ke, namuhla sikulethela i-biography ka U-Edwin Powell Hubble. Ungusosayensi owaziwa ngokuthi ungubaba wesayensi yemvelo yanamuhla futhi othole izinto eziningi ezibalulekile.

Ngabe ufuna ukwazi yonke iminikelo ku-Edwin Hubble nge-astronomy? Kulokhu okuthunyelwe ungazi konke. Kumele uqhubeke ufunde 🙂

Uhlolojikelele luka-Edwin Hubble

Umsebenzi weHubble

Okutholwe ngusosayensi yilokhu okuguqule indlela yokubuka indawo yonke. Wazalwa ngo-1889 futhi, yize kungabonakala kuhlanya, waqala emhlabeni wommeli. Imithetho yezobulungiswa yayingahlangene nakancane nemithetho ye-physics nendawo yonke. Kodwa-ke, ngemuva kweminyaka eminingana, wabuya wazothola iziqu zobudokotela kwezesayensi yezinkanyezi. Ngenxa yokusetshenziswa kwesibonakude, u-Edwin Hubble ukwazile ukuthola inqwaba yemithala emisha ngo-1920.

Kuze kube yilowo mzuzu bekucatshangwa kuphela ukuthi sisendaweni enomkhawulo lapho umkhawulo uhlala khona ngendlela yobisi. Ngenxa yokutholwa kwabanye abaningi, ukuqonda indawo yonke kwaba lula. Umuntu Akuyona neze indawo ephakathi nendawo. Ngaphezu kwalokho, asilutho njengamazeze amancane ngaphakathi kwendawo enkulu.

Okutholwe okubaluleke kakhulu

U-Edwin hubble

Enye yezinto ayibonile yakhombisa lokho i-nebulae babekude kakhulu. Lolu cwaningo lwenziwa ngonyaka we-1925 nokuyilapho kwabonakala khona ukuthi ama-nebulae ayesecishe kube yisigidi seminyaka yokukhanya futhi ngenxa yalokho, abengeke abe yingxenye yeMilky Way.

Okunye okutholwe okubaluleke kakhulu uHubble ayenakho ngemuva kophenyo lwe izinkanyezi ezahlukahlukene zeCepheid ezitholakala kwi-nebula ye-Andromeda. I-Andromeda ingumthala ongomakhelwane esinawo futhi nakanjani ozosihlasela kungakapheli izigidigidi zeminyaka.

Kakade ngalesi sikhathi kwakukhona okutholakele okuhle ngemigodi emikhulu emikhulu nombono wokuthi yonke imithala endaweni yonke inomunye wayo enkabeni yayo. Yebo, njengoba ufunda. Lezo zimbobo ezinkulu ezimnyama ezinkulu ezikwazi ukugwinya yonke into ezungeze futhi ikwenze inyamalale yilokho okulawula isikhungo seMilky Way, umthala wethu. Noma kunjalo, akukho okumele ukhathazeke ngakho. Ukunyamalala kwempilo yomuntu kutholakala ngezindlela eziningi. Noma ngenxa yezinhlekelele zokuguquka kwesimo sezulu, ukuphela kwempilo yeLanga, ukuwa kwesibhakabhaka, izivunguvungu zelanga, njll.

Konke lokhu kwatholwa nguHubble ngonyaka we-1920. Ngokufunda kabanzi ngokuguquguquka kwendawo yonke, wakwazi ukubona ukuthi umhlaba unwebeka kanjani nokuthi lapho kuvela khona i-Hubble njalo, okuyi lowo osetshenziswe ku-physics ne-astronomy ukuchaza ijubane lokukhula kwendawo yonke.

Iminikelo yesayensi yezinkanyezi

Ukutholwa kweHubble

Ngenxa yokwakhiwa kwe-Hubble njalo, kuye kwenzeka ukubala ukuthi indawo yonke ibisanda kangakanani ukuze yazi ubudala bayo. I-Big Bang Theory isitshela ukuthi indawo yonke eyaziwayo yaqala ngokuqhuma okukhulu okwakhipha inani elikhulu lamandla aqukethe. Ubudala bendawo yonke yiminyaka eyizinkulungwane eziyi-13.500 billion futhi lokhu kwatholakala ngu-Edwin Hubble.

Ngaphezu kwalokho, ngale datha uthole ukuthi indawo yonke iqukethe amandla amnyama. Lolu hlobo lwamandla luyimbangela yokuthi imithala ihlale ihlukane njalo. Yiyo futhi "ehlohla" imithala ukuze indawo yonke iqhubeke nokukhula ngokuqhubekayo.

U-Edwin Hubble ukwazile ukubamba izigaba zokuqala iplanethi enazo lapho iqala ukwakheka. Le datha itholwe ngenxa yokuthatha izithombe ezahlukahlukene zediski yothuli negesi ekhona ezungeze inkanyezi esanda kuzalwa futhi ethola ukuqina okukhulu. Njengoba into ithola ubukhulu obukhulu, ivumela ezinye izinto ezizungezile ukuthi zihlangane kancane kancane ngenxa yokwanda kwamandla adonsela phansi. Yile ndlela iplanethi eyakhiwe ngayo.

KuHubble, omunye weminikelo yakhe emikhulu kwezesayensi kwaba ukutholakala kwemolekyuli ephilayo emkhathini we-exoplanet.

Umbono ka-Edwin Hubble

IHubble Bio

Manje sizoqhubeka nokuchaza ngokujule ukuthi uyini umbono owenza u-Edwin Hubble adume. Futhi ngukuthi ithiyori yakhe ingumlingiswa ophambili womthetho kaHubble, nokuyinto echaza ukuthi yonke imithala isuka komunye nomunye ngejubane elilingana nebanga labo. Le nhlangano ingenxa yokuthi ukuqhuma okwenzeka ngemvelaphi yendawo ngesikhathi seBig Bang, kuyaqhubeka nokudedela amandla.

Awekho amandla adonsela phansi noma ukungqubuzana endaweni yonke. Ngakho-ke, uma kungekho lutho lokumisa lawo mandla aqhuba i-Big Bang, indawo yonke izoqhubeka nokwanda futhi ngalokhu, imithala izoqhubeka nokuhamba ngejubane elingaguquguquki.

Ngokuqhathanisa phakathi kwemithala ehlukene ayitholile wakwazi ukusungula ubukhulu bobudlelwano obuqondile ukuze engeze emthethweni kaHubble. Kusukela kulokhu okutholakele wafinyelela esiphethweni sokuthi indawo yonke inokwakheka okufana.

Ngenxa yeminikelo kaHubble ekwandisweni kwendawo yonke engaguquki, namuhla kuyaziwa ukuthi Uma sibheka umthala wethu kusuka noma yikuphi endaweni yonke kuzohlala kufana njalo. Lokhu kungenxa yokwanda okuhlala njalo okutholwa indawo yonke.

Kokubili imfundiso yakhe kanye nazo zonke izifundo zakhe nocwaningo kube nemiphumela emihle kwezesayensi yezinkanyezi kanye ne-cosmology namuhla. Ukuvela kwemithala, kubalwa iminyaka yendawo yonke, izinga lokukhula enalo nazo zonke izihloko ezihlobene nendawo ejulile zinendawo yokubonga ku-Edwin Hubble.

Njengoba ukwazi ukubona, lo sosayensi owaqala njengommeli wenze amagalelo amaningi futhi abalulekile kusayensi.
