As we know from special theory of relativity, time flows slower for a moving observer. But also, thanks to gravity, time ticks slower and faster depending on whether the gravitational force is stronger or weaker. This f.ex. means that time will flow slower for a person living on the 10th floor of a building than a person living on the 1st floor. The most precise device for measuring time on earth is the atomic clock. The atomic clock measures time by using the signals of the electrons in atoms, which emits when it charges energy levels. So, does this mean that the electron charges levels faster when it's pushed by stronger gravitational force (the person on the 1st floor) ? Or the electron emits more signals on charging, when it's pushed by weaker gravitational force (the person on the 10th floor) ?
