Time dilation observed in each frame

  1. Feb 10, 2014 #1
    There are only two frame moving relative with each other at certain velocity. One frame see the other going right and the other to the left.

    Isn't it contradict that each see the other time running slow and both are correct?

    And this isn't the case , where one twin leave earth and each see each other leaving. In this one experience acceleration and rest other details explanation is existed.

    Its a simple question, but I'm unable to answer.

    There is no contradiction, as long as you also allow for the relativity of simultaneity. There are a number of other threads in this forum explaining how this works. For example www.physicsforums.com/showthread.php?t=729941 and https://www.physicsforums.com/showpost.php?p=4556116&postcount=16

    In this case the situation is not symmetrical because one twin experiences acceleration and the other doesn't. Because the situation is not symmetrical, there's no reason to expect them both to believe that the other's clock is running slow, and indeed they will both agree that the accelerated twin is the slow one. You should carefully study the FAQ at http://math.ucr.edu/home/baez/physics/Relativity/SR/TwinParadox/twin_paradox.html, come back if after reading that you still have quations.
