Izixhobo ze-LCP-18 zoMlinganiso weSantya sokuKhanya
Ukusukela oko uGalileo wazama ukulinganisa isantya sokukhanya ngenkulungwane ye-16, abantu basebenzise ezobuchwephesha obuphezulu ukulinganisa isantya sokukhanya ngamaxesha ahlukeneyo. Ngoku, umgama ohamba ukukhanya ngexesha elithile uye waba ngumgangatho weyunithi kuwo wonke umlinganiso wobude, oko kukuthi, "ubude bemitha bulingana nomgama ohamba ukukhanya ekukhanyeni kwisithuba se-1/299792458 kwisithuba sesibini." isantya sokukhanya sikwasetyenziswe ngokuthe ngqo kumlinganiso womgama, isantya sokukhanya sihambelana kakhulu neenkwenkwezi. Isantya sokukhanya sisiseko esisisiseko esibalulekileyo kwi-physics. Zininzi ezinye izinto ezinxulumene nayo, ezinje ngeRydberg rhoqo kwi-spectroscopy, ubudlelwane phakathi kokuvuthwa kokuthambisa kunye nokuqhutywa kwezinto ezisebenza ngombane, i-radiation yokuqala yemitha kunye neyesibini eqhubekayo kwimitha ye-Planck ye-radiation yomzimba, Ubunzima beeproton, i-neutron, ii-electron kwaye iimons zonke zihambelana nesantya sokukhanya C.
Uvavanyo olukhethiweyo: Linganisa isalathiso sokuphinda usasaze imithombo yeendaba ezahlukeneyo njengeglasi ye-organic, i-quartz eyenziweyo kunye nolwelo ngokusebenzisa ityhubhu yemidiya.
