I asked this in physics when I first heard the twin experiment. The answer comes from more complicated relativity based on acceleration and depends entirely on which reference frame you meet in. If you travel back to earth you age slower, if the twin catches up to you they aged slower.... It's not intuitive but time actually warps and there is no true concept of "simultaneous" in a special relativity world.
