Question subsidiaire : un photon n'a pas de temps propre.Je ne vois pas pourquoi il n’aurait pas de temps propre.
N'est ce pas logique?
Parce que tout le monde le sait.
C'est d'ailleurs ce que dit ton équation Vr=Vo/sqrt(1-Vo²/c²)
Si tu poses x=Vr.Tr=Vo.To=Vapp.Tapp.
Tu as aussitôt Tr=To.sqrt(1-Vo²/c²).Je suis plutôt de l’avis de Toutain (décidément !).
Et donc, si Vo=c, sqrt(1-1)=0et To est infini, et "l'infini c'est long, surtout vers la fin" (Coluche).
