Ndechekare zvakadini zvakasikwa sei kuverenga zera racho uye?

Pane zvakawanda yokufungidzira sei wekare zvakasikwa panguva. With neMhedziso chokwadi kuti mubvunzo wezera rake zviri ikozvino hazvibviri kupindura. Uye angangotadza nokusingaperi kukwanisa kuwana mhinduro chaiyo. Asi masayendisiti aiitisa zvidzidzo zvakawanda uye Masvomhu, saka kuti ikozvino musoro wenyaya zvikuru kana zvishoma zvakajeka pepa rehurukuro.

tsananguro

Usati watanga nyaya sei kare zvose, zvinokosha kuti vanoti: zera racho rwunoverengerwa kubva nguva apo yakatanga kukura.

ΛCDM-muenzaniso akasikwa kuziva mashoko. Masayendisiti vanoti kuti anogona kufanotaura kuti nguva pakutanga eras siyana. Asi zvakadaro, sei wekare ndiyo zvose, unogona kuwana kuburikidza nokuwana mukuru zvinhu nenzira zera kadambari.

Uyewo kukosha guru pakurira periodization. Mazuvano, pane katatu, iyo inozivikanwa vamwe ruzivo. Chokutanga - tanga. Inonzi Planck nguva (10 ^-43 masekonzi mushure Big Bang mavambo). Kana uchitenda masayendisiti, iyi yakatora kusvika 10 ^-11 s. Anotevera ichikosha akaramba 10 ^-2 s. It kunoratidzwa nechitarisiko quark nezvimedu - zviri chikamu hadrons, kureva, zvokutanga nezvimedu dzinobatanidzwa zvenyukireya mukukurukurirana.

The okupedzisira nguva - ano. Iye akatanga 0.01 masekonzi mushure Big Bang. Uye kutaura, yazvino nguva runogara kusvikira nhasi.

Kazhinji, maererano achangopfuura data, chadenga zvino mabhiriyoni 13,75 makore. Akabvumira kururamiswa (± 0,11 billion).

Nzira pakuverenga yakavakirwa chando nyeredzi

Pane imwe nzira kuziva kare sei muchadenga. Uye ari vachiongorora kuti anobuda dzinonzi dwarfs chena. Ndivo miviriwo yekudenga yakakwirira chaizvo kutonhora zvikuru mupfupi. About ukuru Earth. Dzinomirira wokupedzisira pavaipfuura ariko chero nyeredzi. Kunze avo kuti zvisingapindirani huru yese. The chena zvipfupi Nyeredzi anova pashure zvose zvayo yenyukireya mafuta nokupiswa. Vasati kuti, iye akanga achiri kuwana zvimwe nenyonganyonga. Somuenzaniso, kwenguva yakati, inova dzvuku hofori.

Uye unogona sei kuwana ekare sei zvakasikwa, achibatsirwa dwarfs chena? Kwete kutaura kuti nyore, asi masayendisiti kubudirira. Dwarfs vapise rehydrogen kwavo zvishoma nezvishoma, zvokuti upenyu hwavo span vanogona kusvika mazana emamiriyoni kwemakore. Uye nguva yose iyi kuti vanoberekwa kunokwana pamusaka simba. A newokuti zvichitonhorera pasi. Uye masayendisiti, pakuverenga mwero kutonhora, huwandu nguva kuti zvakafanira kuderedza tembiricha nyeredzi kubva nezvaiva yepakutanga (yemanyorero, ndizvo 150 000 K). Kuverenga sei kare zvakasikwa ariko, unofanira kuwana coolest dwarfs chena. To musi, vakakwanisa kuwana nyeredzi ane tembiricha anenge 4000 K. Scientists kuongorora vachinyatsoongorora ose mashoko kwakavakirwa mashoko aya, kutaura kuti zvinhu zvakasikwa havagoni kuva makore anopfuura mabhiriyoni 15.

Kudzidza idenderedzwa amazambiringa nyeredzi

Vanofanira kushanda kuti nzira iyi, achiudza wekare sei zvakasikwa, maererano masayendisiti. namasumbu izvi dziri mune peripheral mapazi hweGwara Way. Ivo pairi ichitenderera mwoyo weatomu. A Kutsunga musi inotungamirwa ravo rinobatsira kuwana kubva rezasi muganhu zera zvakasikwa.

Zvichiitika zvazviri kunzwisisa. Zvisinei, ayo chaizvoizvo nhema chete imwe pfungwa. Mushure namasumbu zvose vape- rimwe gore. Saka ivo simuka, tinogona kutaura panguva iyoyo. Uye rehydrogen nokupiswa mune dzimwe mari mukati yakati nguva. Sei painoguma? The pakuonekwa jena pfupi kana Nyuturoni nyeredzi inotungamirwa.

Makore akawanda akapfuura, ongororo iyi mhando kuitwa muchadenga kunoongorora vaishandisa ACS kamera Space Telescope, inozivikanwa se "Hubble". Saka, maererano masayendisiti sei yakare zvakasikwa? Muchadenga kunoongorora akawana mhinduro, uye rinoenderana pamutemo mashoko. Age namasumbu kuti nezvokumwe, semutongo neavhareji mabhiriyoni 12.8 makore. Chinonyanya "mukuru" yaiva mabhiriyoni 13.4.

On the yepasi pose mutinhimira

Pano, kazhinji, takazoziva kuti maererano Masvomhu masayendisiti. How wekare ndiyo zvose - hazvibviri kuziva chaizvo, asi mamwe mashoko anogona kuva anofungidzirwa mufananidzo, vazvione. kuti yepasi pose mutinhimira. kudzidza vakaperekedza vachiongorora Explorer 80 anenge 15 apfuura. Takaendeswa nyaya tembiricha nokufamba uye ari CMB. Kana musingadi kupinda mashoko, ipapo takazoziva kuti muchadenga chedu, Ungangove, makore mabhiriyoni 13.5-14.

Uye vose, zvose havagoni kuva sezvataitarisira. Pashure pezvose, nzvimbo - zvinoshamisa hombe uye aisatombowanika nzvimbo. Asi zvakafadza kuti kutsvakurudza yake nokushingaira mberi.
