Ko te Passage: ko te spacetime metric. Isotropic me homogeneous rongoā o enei whārite whakarei, te Friedmann <unk> Lemaître <unk> Robertson <unk> Walker rongoā 1980, tukua physicists ki te tauira i te ao e kua whanake i runga i te 14 piriona tau i mua i te wera, tīmatanga Big Bang wāhanga. Kia kua whakaritea te maha iti o ngā tawhā (hei tauira i te kikokiko o te kikokiko o te pāmahana ki te kiato), ka taea te whakamahi i ētahi atu raraunga mātakitaki ki te hoatu i te tauira ki te whakamātautau. matapae, katoa angitu, ngā te maha tuatahi o ngā huānga matū i roto i te wā o te nucleosynthesis tuatahi, te hanganga nui-tauine o te ao, me te tīariari me ngā āhuatanga o te "raro thermal" i te cosmos wawe, te kitenga cosmic.
