Hi

You know how Atomic clocks in orbit have to be reset because bending spacetime or something. What is actually happening? Do the clocks go slower (or faster) in a weaker gravitational field? Is the difference the result of atomic decay being variable in differing gravitational fields?
Also if there is a time difference( say between a clock on Earth and one in orbit) if we were to physically move the clocks so they met in the same gravitational field i.e. the surface of the Earth would the clocks right themselves and become synchronous?
