Twin paradox

  1. Mar 30, 2008 #1
    form twin paradox, let say Jerry is the one go travel to outer space then back to earth and Tom is the one stay in earth.

    From relativity time dilation,Tom will see time in Jerry will be slower and also for Jerry will see Tom time move slower.

    So, just at the time Jerry reach the earth(he spacecraft still moving), he will see Tom actually younger than him. But when the spacecraft land on earth, Jerry now see Tom is older than him. So, what actually happen here? thks
