That has nothing to do with my post. I said the rate at which an atomic clock ticks is determined by the physical state of the space in which it exists. Gravitational force is a physical state of space.

Ever hear of gravity? And what do you think occurs when the clock is at the center of the Earth? Does it tick at the same rate as it would in 'empty' space because there is no gravity at the center of the Earth? Of course, not. An atomic clock will tick slower at the center of the Earth than it will on the surface of the Earth. The rate at which an atomic clock ticks is determined by the physical state of the space in which it exists.
