The twin paradox is very confusing, and even after reading the explanation, I still get questions. The only explanation of the paradox is when an object is first moving away from earth, and then moving towards the earth. They make it very complicated. How about just moving one direction, and then stop. Let's say that an object moves one lightyear from earth in the rest frame in a straight line for an average speed that makes the dialation for the object 0.5 in the rest-frame. The object will see the earth move away from it, and assume it is dialated by 0.5 as well. When both observe this, what will be true when the object stops? Will the object be "older" or will the earth be?
