   For example, if I put two clocks at the maximum distance on the floor,   
   they remain synchronized and, therefore, horizontally there is no   
   acceleration (there is quiet).   
      
   If, on the other hand, I put a clock on the floor and one on the   
   ceiling, they don't stay synchronized and, therefore, there is   
   acceleration vertically (there is no quiet).
