Does anyone have a calculation for measuring geodesic deviation?

14 April 2014 0 5K Report

Does anyone have a calculation for how much grows the "distance" between two points that follow 2 separate geodesics next to each other (maybe only tracing radial directions and noticing the shifting time-space like coordinates r,t --> t,r, perhaps using the equation of geodesic deviation) and referring to the black hole, i.e the inner region of a event horizon for a Schwarzschild metric? This question arises from the possibility of identifying which aspects are common to the Schwarschild metric (inside the event horizon) and the FLRW cosmological model of expansive universe.
