The Schwarzschild Metric on a spacial plane passing through the center of a spherically symmetric (non-spinning) center of gravitational attraction is:



If there are two spaceships at a distance r1 from a gravitating body, and one moves radially (dφ = 0) to a radius r2, in a time τ1 as measured by its own clock, and then immediately returns from r2 to r1 in a time τ1, how much time will have elapsed on the clock on the spaceship which remains at r1 ?
