Tirohia te wāhanga i raro nei, kātahi ka whakautu i te pātai i muri mai i te reo kotahi me te wāhanga:  Passage: Ko te mata porohita rite ki tera o te Ao e whakarato ana i tetahi tauira ngawari. Ka taea te whakaahua i te tauwāhi o tētahi wāhi i runga i te mata mā ngā taururuku e rua: te pae matawhenua me te roanga. Kaore i rite ki nga taunga Cartesian o te rererangi, ko nga rereketanga o te taunga kaore i rite ki nga tawhiti i runga i te mata, e whakaatuhia ana i te whakairoiro i te taha matau: mo tetahi i te paenga, ko te neke 30 nekehanga o te roanga ki te hauauru (raina magenta) e rite ana ki te tawhiti tata ki te 3,300 kiromita (2,100 maero), i te mea mo tetahi i te 55 nekehanga, ko te neke 30 nekehanga o te roanga ki te hauauru (raina puru) e hipoki ana i te tawhiti o te 1,900 kiromita (1,200 maero). Na reira kaore nga taunga e whakarato i nga korero e ranea ana hei whakaahua i te āhuahanga o te mata porowhita, i te āhuahanga ranei o tetahi waahi uaua ake, o te waahi ranei. Ko taua mōhiohio tonu te mea kua whakaraupapatia ki roto i te ine ine ine, he taumahi kua tautuhia i ia wāhi o te mata (he mokowā, he mokowā wā rānei) me te pātahi i ngā rerekētanga taururuku ki ngā rerekētanga tawhiti. Ko ētahi atu nui katoa e whai pānga ana ki te āhuahanga, pēnei i te roa o tētahi ānau, te koki rānei e tutaki ai ngā ānau e rua, ka taea te tātai mai i tēnei taumahi ine. Ka taea te whakamahi i te taumahi ine me tōna tere o te huringa mai i tētahi wāhi ki tētahi wāhi hei tautuhi i tētahi nui āhuahanga e kiia nei ko te Riemann curvature tensor, e whakaahua tika ana i te āhua o te wāhi, o te wā rānei i ia wāhi. I roto i te pātahitanga whānui, ko te ine ine ine me te taumahatanga o te piko o Riemann he nui e tautuhia ana i ia wāhi i roto i te mokowā-wā. Ka rite ki kua whakahuatia, te ihirangi take o te wāhi-wā tautuhia tetahi atu nui, te pūngao <unk> momotuhi tensor T, me te parau tumu e "kōrero wāhi-wā take pehea ki te neke, me te take e mea wā wāhi pehea ki te ānau" te tikanga e enei nui kia e pā ana ki tetahi ki tetahi. I whakatakotohia e Einstein tenei hononga ma te whakamahi i te Riemann curvature tensor me te metric ki te tautuhi i tetahi atu nui geometrical G, e kiia nei ko te Einstein tensor, e whakaahua ana i etahi waahanga o te huarahi e piko ai te waahi-waahi....  Pātai: He aha te momo mata māmā e kore e taea te whakaahua mā te whakamahi i ngā taururuku?
