Rhoqo ngexeshana, inzululwazi isiphosa into encinci malunga nohlobo lwexesha elisenza ukuba sifune ukulala phantsi kwaye siyeke ukucinga okwethutyana. Uyazi, njengokuba le nto siyibiza ngoku iyinyani I-80 millisecond kwixesha elidlulileyo , okanye ukuba iinkwenkwezi ozibona ebusuku sele zife nini xa ukukhanya kwazo kufikelela kuthi apha eMhlabeni (nangona Ubaxwa kakhulu NgokukaPhil Plait). Ewe, nantsi enye entsha kuwe: iifoto ezikhanyayo azinamaxesha. Njengazo zonke.
Siqale safunda ngale nto ku-Frasier Cain we-Universe Namhlanje, oweva ngayo isazi ngeenkwenkwezi uGqirha Pamela L.Gay ngelixa babecofa isiqephu se-podcast yabo yeveki nganye, Ubunzululwazi ngeenkwenkwezi. UKayin ucacisa kule vidiyo ingezantsi:
Inqaku elibalulekileyo lingena ngo-0: 23 okanye njalo. Ukusuka kwimbono yeefoton, utshilo uKayin, akukho nto kuthiwa lixesha. Ikhutshiwe, kwaye isenokubakho kumakhulu ezigidi zeminyaka, kodwa kwi-photon, kukho ixesha le-zero elidlulileyo phakathi kokuba ikhutshwa naxa iphinda itsalwa. Ayinamava omgama, nokuba.
Uqhubeka echaza ukuba oku kungenxa yemeko yokuguqa kwexesha kweTheory yoBudlelwane obuKhethekileyo. Okukhona usondela kwisantya sokukhanya, kokukhona uya ufumana ixesha elibonakalayo emzimbeni - oko kuthetha ukuba ukuba ubunokuchitha iminyaka eli-10 uzulazula esithubeni ngesantya sokukhanya, wonke umntu omshiye ngasemva eMhlabeni uyakuba neminyaka elishumi ubudala ixesha ubuyile, kwaye ubuya kujongeka ngokufanayo. (Eli licebo lika Ukuhamba ngenqanawa .)
Nangona kunjalo, ukukhanya kunjalo njalo ukuhamba ngesantya sokukhanya - luhlobo lwento leyo - ke ayikaze ichaphazeleke lixesha. Kwaye ayichaphazeleka ngumgama, kuba njengethiyori ekhethekileyo yobudlelwane kunye neziqendu ezilungileyo ze Ugqirha Ngubani omabini la manqaku, indawo kunye nexesha zihambelana ngendlela engachanekanga.
Ukuthetha nge Ugqirha Ngubani, ukuba siza kuzisa le nto kwi-geeky psuedo-science yintsimi yentsimi (kwaye kunjalo siza kuthi, yabona igama lale webhusayithi?) emva koko ngokucacileyo oko kuthetha ukuba konke ekufuneka sikwenzile ukuze singafi kukusebenzisa amandla okukhanya ukuqinisekisa ukuba asisayi kuze sibe badala. Huh, mhlawumbi abo bantu bavela Imiphefumlo Emnyama bebengekho kude kangako emva kwako konke nokunqula kwabo iLanga. Ukuba nje sonke sinokuba kwi-incandescent gross!
(nge IPhoto.org , umfanekiso nge UMarjan Lazarevski )
- Ngaba kunokwenzeka ukuba ukukhanya kujikeleze umngxuma omnyama?
- Abaphandi bafumene indlela yokubambisa ukukhanya umzuzu opheleleyo
- Abadali beendalo bahleli bekhathazekile ICosmos
