I have always been confused about time dilation in General Relativity.(adsbygoogle = window.adsbygoogle || []).push({});

In the twins paradox, it is the traveling twin that ages slower. However, could you not just as easily say that it is the non-traveling twin that is moving away from the other?

So why is it the traveling twin and not the non-traveling twin that experiences the slowing of time relative to the other.

One difference I can see between the two is that the traveling twin accelerated away from non-traveler. However, the time dilation continues even after the acceleration ceases (i.e. based on velocity, not acceleration).

Another difference would have to do with velocity through an absolute space, but I thought that did not exist.

Please forgive my ignorance, but clearly I am missing something fundamental here. Can anyone enlighten me?
