definition

Kafin ka fara wani labarin game da yadda tsohon sararin samaniya, yana da daraja don nuna ra'ayi: ta shekaru da aka lasafta daga lokacin da ta fara fadada.

ΛCDM-model aka halitta domin sanin data. Masana kimiyya jayayya da cewa shi zai iya hango ko hasashen lokacin da farkon na lokuta daban-daban. Amma har yanzu, da yadda tsohon ne sararin samaniya, za ka iya gano ta gano mafi tsufa abubuwa da sarrafa kwamfuta shekaru.

Har ila yau, na bayar da muhimmanci da aka buga periodization. A zamanin yau, akwai sau uku, wanda aka sani ga wasu bayanai. A farko - farkon. Shi ne ake kira da Planck lokaci (10 ^-43 seconds bayan da Big Bang asalin). Idan ka yi imani da masana kimiyya, da wannan lokaci dade har zuwa 10 ^-11 s. A gaba epoch ci gaba zuwa 10 ^-2 s. An halin bayyanar quark barbashi - yana da wani ɓangare na hadrons, cewa shi ne, da na farko barbashi da hannu a nukiliya interactions.

A karshe zamanin - zamani. Ta fara da 0.01 seconds bayan da Big Bang. Da kuma tsananin magana, da zamani zamanin yana zuwa wannan rana.

A general, bisa ga kwanan nan data, duniya yanzu 13,75 shekaru biliyan. Yarda gyara (± 0,11 biliyan).

Hanyar na kirga tushen sanyi taurari

Akwai kuma wata hanya zuwa ga gano yadda tsohon talikai. Kuma ya aka sa idanu da watsi da ake kira fari dwarfs. Su ne basamaniyai sosai high yanayin zafi ne quite kananan a size. Game da girman da Duniya. Su wakiltar karshe mataki na kasancewar wani star. Fãce waɗanda suka sãɓã wa jũna a cikin babbar masu girma dabam. The fari Dwarf star zama bayan duk ta thermonuclear man fetur da aka kone su. Kafin haka, ta har yanzu jurewa da wasu upheavals. Alal misali, don wani lokaci, shi ya zama mai ja giant.

Kuma ta yaya za ka gano yadda tsohon sararin samaniya, tare da taimakon farin dwarfs? Ba a ce cewa sauki, amma masana kimiyya ci. Dwarfs ƙone hydrogen sannu a hankali sosai, don haka abin da ajalinsu zai iya isa daruruwan miliyoyin shekaru. Kuma duk wannan lokaci ba an haifi mutum godiya ga tara makamashi. A layi daya zuwa kwantar da hankali. Kuma masana kimiyya, kirga kudi na sanyaya, ƙayyade yawan lokaci cewa wajibi ne don rage zafin jiki star daga abin da yake da asali (yawanci, shi ne 150 000 K). Don lissafa da yadda tsohon duniya wanzu, kana bukatar ka sami shaawa fari dwarfs. Don kwanan wata, gudanar ya gano star tare da zazzabi na game da 4000 K. Masana kimiyya nazarin a hankali duk data bisa wannan bayani, da da'awar cewa duniya ba zai iya zama fiye da shekaru biliyan 15.

A binciken da na siffar zobe gungu na taurari

Ya kamata masu amfani da wannan hanya, yadda hakika haihuwa sararin samaniya, bisa ga masana kimiyya. Wadannan gungu suna located in da na gefe sashi daga cikin Milky Way. Kuma suka kewayewa kusa ta tsakiya. A tabbatar da dalilin da kwanan watan da samuwar taimaka wajen gano ƙananan iyakar da shekaru mu talikai.

A tsari ne a zahiri rikitarwa. Duk da haka, ta ainihi ta'allaka kawai wani ra'ayin. Bayan duk gungu fito daga daya girgije. Sai suka tashi, za mu iya ce a lokaci guda. Kuma hydrogen da aka kone a wasu adadi a cikin kayyade lokaci. Yadda shi ƙare? Bayyanar wani farin Dwarf ko neutron star samuwar.

Shekaru da dama da suka wuce, da karatu na wannan irin za'ayi 'yan saman jannati suka yi amfani ACS kyamara Space kawo nesa kusa, da aka sani da "Hubble". Saboda haka, bisa ga masana kimiyya da yadda tsohon halittu? 'Yan saman jannati sun sami amsar, kuma shi yayi dace da hukuma bayanai. Age gungu cewa su bincika, amounted zuwa wani talakawan of 12.8 shekaru biliyan. A mafi "m" ya 13.4 biliyan.

A cikin cosmic rhythms

A nan, in general, mun gano cewa, bisa ga lissafin kimiyya. Nawa ne duniya - ba shi yiwuwa a san daidai, amma mafi bayanai iya zama m adadi, da jawo hankali ga cosmic rhythms. Su binciken gudanar da bincike Explorer 80 game da 15 da suka wuce. Mun aka ɗauke shi zuwa lissafi zafin jiki da hawa da sauka, kuma da CMB. Idan ba ka shiga cikin cikakken bayani, sa'an nan muka gano cewa mu duniya, mafi m, 13.5-14 shekaru biliyan.

Kuma a general, duk abin da ba zai iya zama hanya da muke sa ran. Bayan duk, sarari - mamaki babbar kuma kusan unknown sarari. Amma so cewa da bincike ne rayayye gudana.
