Suppose we synchronize two atomic clocks at a point at 45° south latitude, and then move one clock directly north to the earth’s equator and the other directly south to the south pole, where they remain for some years in climate-controlled enclosures that keep them at the same temperature and humidity. We then reunite the clocks at the origin point and compare them again. Which (if either) has registered a shorter time between the synchronization and comparison events?
A. The clock at the equator
B. The clock at the south pole
C. Both clocks read the same time
A. The clock at the equator
