Le Paradoxe des Jumeaux expliqué avec un court métrage d’animation


Animation, Short Films,

Le « Paradoxe des Jumeaux » ou paradoxe de Langevin est sans doute l’effet le plus célèbre de la relativité restreinte d’Einstein. Voilà donc un court métrage d’animation qui va vous permettre de comprendre pourquoi un jumeau vieilli plus vite que l’autre en voyageant à la vitesse de la lumière dans une fusée. ;) Une court métrage en animation et réalisé par Yuanjian Luo.

    The second guy that spoke sounds like a giant faggot…

    Any transformation between two observers is a space-time dialogue between two entities A and B about a third entity C. In the ‘Galileo Transformation’, the third entity C is understood, does not appear in the notation. But the ‘Lorentz Transformation’ completely ignores the entity C, and this is why the twin paradox.
    I would like to introduce some new transformations that preserve the local velocity of light. Also resolve the twin paradox.

    Hi Guys. Nice animation! I have a few comments though. At 2:10 you say that the ball « actually » travels farther than it appears to the passenger. I would say that this is from the point of view of the person not in the car. Furthermore, there is no absolute « actual » distance that the ball travels…only distances relative to each observer. At 2:39 you mention that light is different than the ball and this is sort of true. Light is massless (sort of) and all its speed is through the space dimension of spacetime where as the ball has part of its speed through spacetime in both the space and time dimensions. At 3:35 you mention that time is also dilated in the car but I don’t see how you can say that. Maybe you can explain it to me. It seems to me that the car and everything in it are part of the same inertial frame and therefore there would not be any time dilation within the car. How did you mean it?

    I’m sorry but I think that you’ll have to ask the authors of the video ;)
