DEF

[A] hypothetical subatomic particle whose velocity always exceeds that of light.

CONT

[Ils] purent démontrer qu'un objet ayant une masse imaginaire et se déplaçant plus vite que la vitesse de la lumière ne viole pas la théorie spéciale de la relativité d'Einstein. Ces particules plus rapides que la lumière et à masse imaginaire furent nommées tachyons.
