Iminyele kunye nokwakheka kwendawo yonke

definition yokungapheli

Indalo - ingqokelela konke olukhoyo yonke. Kuyinto akupheli kwisithuba, kuba umntu akakwazi ukumisela imida yayo. Kuyinto obungunaphakade ngexesha ngenxa yokuba lwandulelwe bang enkulu, yaye emva lungapholi nangoku kuya kwenzeka into apho. inzululwazi Fundamental ukufunda amacandelo ngabanye iphela: Chemistry uphonononga ihlabathi eziphilayo, physics - amasuntswana cebetshu atom, eziphilayo unoxanduva ekufundweni ezi nesenzeko endalo. Indlela esakhiwe ngayo indalo xa iyonke ukufunda ngokuma isekelwe phezu ngobhalo ngeenkwenkwezi.

nemifuziselo yonke

Uphuhliso olukhawulezileyo cybernetics kuphando ezahlukeneyo kuqulathe ukwandisa ukuthandwa theory umzekelo. Undoqo kule mfundiso isifundo le modeli ehambelana nendawo into yokwenene yokuqala. Ukudala imizekelo iziganeko ngamnye igalelo olunzulu ukufunda ihlabathi ezingqongileyo. Kangangexesha elide ngeenkwenkwezi ziye ngenkuthalo wafunda isakhiwo indalo ngengqondo yohlobo olunye (isotropic).

Einstein ecetywayo imodeli zezindlu apho ugobile lobulali elichaziweyo ixesha kunye nelothe nendawo ugobile yehlabathi iphela. Kulo mzekelo, into angazange aguqe ixesha ukuququzelela, okt ixesha ngokufanayo uya ukusuka elidlulileyo ukuya elizayo. Ngapha koko, le modeli kuye kwaphuculwa ezisemajukujukwini Villemom De setter, lowo wacebisa ukuba yangasemva shift ebomvu, ixesha iqukuqela ngokwahlukileyo kwiindawo ezahlukeneyo iphela.

Namhlanje, imodeli ithandwayo iphela landayo ecetywayo yi Friedman. Kulo mbono, isakhiwo iphela uba ugobile ehlabathini kwinginginya rhoqo bayavumelana. Xa lesayensi ziphikisana iinguqulelo ezimbini ekwandiseni imodeli:

- imodeli evaliweyo angenela deceleration ukwanda ngokuthe ngcembe ngenxa deceleration omxhuzulane;

- model vula icebisa nokongezwa linyuke lonke ixesha ngamabona elide.

Naluphi na umfuziselo yonke ikopi nje into yokwenene, yaye ngoko ke iziphumo zokufunda yayo kuphela yeengcingane, zifuna yesiqinisekiso practical.

Galaxy kwindalo iphela

Namhlanje, izazinzulu Umhlaba uyigcine yonke enye kuphela, kodwa hayi sisiseko ngoluvo ukuba wahlukile. Ubume kunye Evolution of the Universe ngumceli-mngeni jikelele izifundo khozimologi.Sonke. Zonke iinkwenkwezi zalo kunye imizimba yasezulwini zadityaniswa kwiqula elikhulu iinkqubo inkwenkwezi, ebizwa iminyele. okuwo ngalinye engundoqo engundoqo, iingalo ezijikeleze ngeenxa zonke kuye, nginginya inani elikhulu zeenkwenkwezi, kunye kwimida kwi ngohlobo amafu, equka iinkwenkwezi ezinqabileyo. Stars bezalwa, niphile, ihamba isithuba, bafe. Kumnyele wethu, inkwenkwezi engundlunkulu iLanga, imizimba yasezulwini, njengaye, baphile iminyaka eli-10 ukuya kweli-15 ezigidi. Ngoku ilanga kwi yobudala ephakathi.

KwabeMi esiphila kuthiwa iMilky Way kuba moya yawo kunye nani liphezulu iinkwenkwezi, irhasi kunye uthuli iyabonakala esibhakabhakeni ebusuku ngathi bugcwele yinkungu. Le band yale ukukhanya ezingqonge ijikazi ngokubanzi kwezulu lonke. Milky Way - kumnyele asiyiyo yodwa, icandelo isakhiwo iphela. Kukho inani enkulu iminyele ineenkwenkwezi ezingenakubalwa. Umzekelo, kumnyele Andromeda kunye Magellanic Amafu, ibekwe kwi umgama nanto kuthi.

Ubume ukwabiwa kwezinto

Indlela esakhiwe ngayo indalo zokwanda flat sheets galactic, ezahlulwe kwimimandla apho kakhulu akukho izinto luminescent. Ezi mgodini babe ubukhulu malunga 100 iMPC. Iphepha lokuqala emsebenzini Great Wall, zibekwe kumgama million 200 iminyaka elula. Great Wall - iqela leminyele, ukuba ubukhulu 15 million ukukhanya .. ubudala kunye nobukhulu - million 500 DM .. iminyaka.

Xa isakhiwo nomhlaba ngesigqibo Umhlaba ezi mpawu zilandelayo: wezijikelezi-langa, iqela lasekuhlaleni ezisebenzisanayo abumbe zeminyele, ingalo Orion, kumnyele - iMilky Way.
