WebGeodesic equations of the FRW metric (Christoffel symbols) I've found the non-zero Christoffel symbols for the FRW metric, using the notation , Now I'm trying to derive the … In general relativity, the metric tensor (in this context often abbreviated to simply the metric) is the fundamental object of study. It may loosely be thought of as a generalization of the gravitational potential of Newtonian gravitation. The metric captures all the geometric and causal structure of spacetime, being used to define notions such as time, distance, volume, curvature, angle, and separation of the future and the past.
