Ok I have attached a picture of what I am talking about. A, B, C, represent people with clocks. And A is at rest with respect to the middle of the planet. A, B , C all synchronize their clocks . Then B and C start to orbit around the planet with the same speed but in opposite directions. then they will meet on the other side and then eventually meet back where A is. in A's frame wont B and C's clock be dilated the same amount. So A would see B and C's clock reading the same time. In B's frame wouldn't he see C's clock to be running different than his. Ok now my question is when B and C go around the planet once and meet up back with A. If A see's B and C's clock to be the same, would B see C's clock to be different?
