Motion is relative. According to special relativity in inertial frame an object is always at rest and all objects clock ether ticks the same or slower as the observer. They tick the same is if they are at rest with the observer or moving in the same direction with the same speed.
But no clock moves faster.
The Paradox:
Two inertial objects located at a reasonable distance in empty space with respect to each other with no other frames to come in play or interfer.
You are in one and your twin is in the other.
How would anyone of you determine who is moving and who is not or who ages less or more than the other?
Good luck. I don't have the answer and I have never seen the answer. All the other answers are not related to the actual twin paradox although they make it look like it is.
