Pardon my ignorance, if we have two identical clocks and we use them to measure time dilation.
Suppose we have two identical clocks one in a Satellite around the earth and one on the ground. Now the clocks are mechanical and consist of moving parts. Does the clock in the satellite run faster because it's parts are turning slowly? Or does this have to do with the observer on the ground seeing the clock turning faster due to the amount of time it takes from the clock to reach the observer on ground.
