Mapoka enyeredzi uye maumbirwo wezvose

tsananguro kusaverengeka

Muchadenga - dzakaunganidzwa zvose kuti chiri pezvakasikwa. It ane muchadenga, nekuti munhu haagoni kunan'anura pakunogumira. Hazvina usingagumi nguva nokuti pashure guru bang, uye pashure kutonhora ichiri chinhu zvichaitika ikoko. Chinokosha sainzi kudzidza nomumwe zvinoumba zvakasikwa: Chemistry rinoongorora samolecular nyika, wefizikisi - zvokutanga nezvimedu uye maatomu, zvipenyu ndiye pakudzidza ari mananara zvakasikwa. Sechivako muchadenga rose iri kudzidza cosmology iri uchifungidzira nyeredzi.

yokutevedzera zvakasikwa

Kukurumidza kukura cybernetics pakutsvakurudza siyana zvaiva kuwedzera kukurumbira pakati Modelling dzidziso. Musimboti dzidziso iyi kudzidza muenzaniso unoenderana chokutanga chaicho chinhu. Kuumba yemashoko nomumwe mananara kubatsira zvakadzama kudzidza yakapoteredza nyika. Kwenguva refu nguva vanoongorora zvenyeredzi kushingaira kudzidza maumbirwo zvakasikwa uye yokufungidzira homogeneous (isotropic).

Einstein akafunga muenzaniso cylindrical umo dzeko curvature yakajeka nguva uye nzvimbo achitungamirira yose curvature wezvose. In muenzaniso uyu, nguva rinoronga haina hwakakungwa, kureva noruvara nguva anoenda kubva kare kuti ramangwana. Uyezve, muenzaniso uyu rave nani astrophysicist Villemom De zvinofanira kutevedzerwa hadzina chinodzirwisa, uyo akataura kuti pakanyorwa tsvuku kusuduruka, nguva runoyerera zvakasiyana munzvimbo dzakasiyana-siyana zvakasikwa.

Nhasi, inonyanya kufarirwa muenzaniso rakawedzera zvakasikwa, wakatangwa na Friedman. In pfungwa iyi, nemamiriro wezvose ane pose curvature pamusoro nguva dzose gravitating zvavo. Munyika yesayenzi nharo okunatsiridza maviri kuwedzera muenzaniso:

- up womuenzaniso achipfeka nezvishoma deceleration kuwedzera somugumisiro rinokweva deceleration;

- muenzaniso rakavhurika rinoratidza tava kuderera kuwedzera munyika imwe nguva inopfuura refu.

Chero muenzaniso wezvose zvakasikwa chete kopi chaiye chinhu, uye saka migumisiro yacho yokudzidza evasingatombonamati yokungotaura, ivo zvinoda mazano chisimbiso.

Renyeredzi mune zvose

Nhasi, Earth masayendisiti vanocherechedza zvakasikwa chimwe chete, asi haisi hwaro kutaura kuti zviri rakasiyana. Marongerwo uye Evolution of Universe ndiyo yose chinetso cosmological zvidzidzo. All nyeredzi dzaro uye mitumbi yokudenga akabatanidzwa kuva chihombe nyeredzi mugadziriro, akadana enyeredzi. Mumwe renyeredzi ane nechepakati paro, dziri zononoka maoko vakamupoteredza, iyo inoshandiswa vakawanda nyeredzi, uye arikunze iri muchimiro makore, raiumbwa isingawanzowanikwi nyeredzi. Stars vanoberekwa, kurarama, uchifamba muchadenga, uye kufa. In redu renyeredzi, musimboti nyeredzi ndiye Sun, zvisikwa, kufanana naye, kurarama kubva 10 kusvika 15 bhiriyoni makore. Zvino zuva iri pakati zera.

The renyeredzi yatiri kurarama anonzi hweGwara Way nokuti ndege dzaro kunonyanyisa nhamba nyeredzi, gasi uye guruva riri kuoneka mudenga somunhu pwititika chomwedzi usiku. Boka sokupenya ichi runopoteredza rakafara chindori pedenga. Gwara Way - the renyeredzi hakusi chete, chezvinonhuwira sechivako wezvose. Pane rakakura nhamba emapoka pamwe wandisa nyeredzi. Somuenzaniso, kuti gwara rinonzi Andromeda uye Magellanic Makore, riri pamusoro sanzwisisika kure nesu.

Sechivako kuparadzira nyaya

Nemamiriro wezvose zvakasikwa kuunganidza sandara machira Galactic, akaparadzaniswa nevanhu kumatunhu umo substantially hapana luminescent zvinhu. voids izvi vane saizi vanenge 100 Mpc. jira The rokutanga vakachengeta Great Wall, riri kure mamiriyoni 200 chiedza makore. Great Wall - boka emapoka enyeredzi, vane Ukobvu miriyoni 15 chiedza .. zera uye kukura - mamiriyoni 500 DM .. makore.

In nemamiriro wezvose nzvimbo Nyika ine zvinotevera unhu: zuva yemapuraneti ezvinhu, imwe munharaunda boka zvisumbu uye zvisumbu zvikuru emapoka enyeredzi, ari Orion ruoko, kuti renyeredzi - hweGwara Way.
