Takion

Takion (Jawi: ‏تاكيون‎code: ms is deprecated ‎) ialah suatu zarah yang dibayangkan dapat bergerak lebih pantas daripada kelajuan cahaya. Kebanyakan ahli fizik percaya bahawa zarah sebegini tidak wujud kerana prinsipnya tidak konsisten dengan hukum-hukum fizik yang sedia ada atau diketahui;^[1]^[2] seandainya keadaan sebaliknya berlaku, maka zarah tersebut boleh digunakan untuk membina suatu antitelefon takion (tachyonic antitelephone) yang menghantar isyarat lebih laju daripada kelajuan cahaya lalu melanggar sebab akibat (causality) dalam fizik jika mengikut kerelatifan khas.^[2]
