I was just curious as to how someone could find a Quantitative answer out of the equations for general relativity. I've tried to mess around with stuff related to tensors and manifolds but yeah, I can only compute so much given my foundation. In an attempt to build and forge that foundation I try and obtain some answers. My one question was how did Einstein calculate red shift and that sort of deal. Also, how could someone obtain any quantitative answers to any sort of problem. For instance. what if there were two bodies of mass in some distant corner of the universe. Each was of a different but significant difference in mass. What would be the amount that the light would bend if it were traveling between the two bodies.
