We are (finally!) at the point where we can begin to examine the detailed predictions of General Relativity. Here we start investigating the simplest non-trivial problem of a uniform gravitational field, or, equivalently, of an observer undergoing uniform acceleration. We find that the theory makes the incredible prediction that clocks in a gravitational field appear to run at different rates, so called gravitational time dilation.
