A siffar, tsarin da Girman sararin samaniya

A cosmology, akwai har yanzu babu bayyana amsar tambayar, wanda rinjayar da shekaru, da kuma siffar Girman sararin samaniya, kuma babu wani yarjejeniya game da wata gabar jiki. Domin idan samaniya yana guntun, to, shi dole ne ko dai ji ƙyama ko fadada. A wannan yanayin, idan shi ne iyaka, da yawa zaton su ne m.

Back a 1744 da falakin JF Cheseaux farko shakka cewa duniya iyaka, saboda idan yawan taurari yana da wani kan iyakoki, don me ba haske sama da kuma me ya sa yake da shi duhu? A 1823, G. Olbes jãyayya gaban da iyakoki da sararin samaniya don haka wannan haske zuwa ga Duniya daga m taurari ya kamata ya zama weaker saboda da sha na wani abu da yake a cikin hanyar. Amma a wannan yanayin da kanta, wannan abu dole ne mai tsanani ga haske, kuma babu mafi muni fiye da kowane star. Wannan zato aka tabbatar da kimiyyar zamani, wanda ya bayyana cewa da wuri ne "kome ba", amma a lokaci guda yana da wani real jiki Properties. Hakika, da sha na injin samar da makamashi photons take kaiwa zuwa wani karuwa a cikin zafin jiki, sakamakon cewa da injin zama sakandare tushen radiation. Saboda haka, idan Girman sararin samaniya, lalle iyaka, hasken taurari da kai iyakar nesa ne da karfi ja shift cewa yana farawa zuwa ci tare da bango (secondary) radiation injin.

Duk da haka, wanda zai iya ce cewa Girman sararin samaniya, wanda aka lura da 'yan adam, ba shakka, a matsayin karshe da kanta da kuma gudun haske. Distance 24 ne ya yi iyaka da haske Gigaparseksa m sararin sama. Duk da haka, saboda gaskiyar cewa fadada kudi ƙaruwa, ƙarshen duniya ne, a wata nisa da biliyan 93 haske shekaru.

A mafi muhimmanci sakamakon cosmology shi ne Hujjar cewa sararin duniya ta fadada su. Yana da aka samu ta hanyar kallo na redshift, sa'an nan samu a gwada yawa kima daidai da Hubble ta dokar. Wannan shi ya haifar da masana kimiyya ya kammala da cewa, Big Bang Theory sami ta tabbatarwa. A cewar NASA, wanda aka samu da WMAP, da shekaru na sararin duniya, daga Big Bang, 13.7 shekaru biliyan abõkan tãrayya. Duk da haka, wannan sakamakon shi ne zai yiwu ne kawai idan muka ɗauka cewa model, wanda ya ta'allaka a kan tushen da bincike ne daidai. Lokacin amfani da sauran daraja dabaru samu gaba ɗaya daban-daban data.

Shafi tsarin na sararin duniya, ba za a ce game da halittarsa. Ya zuwa yanzu ba a gano cewa, da uku-girma siffar cewa zai fi kyau wakiltar ta image. Wannan matsala mai tushe daga gaskiya cewa ya zuwa yanzu shi ba a san ko sararin samaniya ne lebur. Na biyu al'amari ne alaka da cewa shi ne a ga wasu da aka sani game da mahara sadarwa. Haka kuma, idan Girman sararin samaniya spatially a daure, a kan madaidaiciya Lines a wani shugabanci na iya zama wani masomin.

Kamar yadda zamu iya gani, fasaha ci gaba ya ba ta kai matakin a daidai amsa tambayoyi game da shekaru, naúra da kuma Girman sararin samaniya. Har yanzu, da yawa theories a cosmology ba a tabbatar ba, amma ba a karyata.
