Suppose we have a large circular disk with pegs around the perimeter, and we set the disk rotating so that one pegs passes us every second. Then, we move this disk to a gravitational field, such that one side of the disk is closer to the gravitational mass than the other. From our perspective at the far side of the disc, we continue to observe one peg passing per second. Meanwhile, one assumes, an observer placed at the near end (closer to the gravitational mass) similarly observes one peg passing per second on his side. My questions: 1. Does the far observer, looking toward the side of the disk closer to the mass, see one peg per second passing the other observer? (Seems like he couldn't, since he would observe a clock at that location running slow.) 2. In order to accommodate that, does the far observer notice some aspect of the disc changing (spatial or otherwise)? In other words, what must happen in the observation of the disc to prevent the "faster" pegs from appearing to catch up with the "slower" ones"? I am trying to imagine how this scenario would appear to the far observer as the disc rotates. Thank you.
