Galilei tries out geodesic deviation
09 Feb 2022Imagine to release two test masses (i) at the same time at two different locations and (ii) at the same location at two different times in a homogeneous gravitational field. Why is the distance between the two masses is constant in the first case and why does it change quadratically in the second? what would be the reason from the point of view of relativity and curvature?
