A few words about what I am working on now and what I will be trying to do. The next step will be an approach of General Relativity from two different angles. The first is to try to introduce gravitation in the model of Proper Time Adjusted Special Relativity. The second will be to formulate General Relativity in extrinsic terms, and see if it agrees or not with what I will have come up through the Adjusted Special Relativity model. The intrinsic formulation of Tensor Calculus has obviously been very fruitful, but I suspect that an extrinsic formulation will be even more so, because it will show much more clearly how gravitation is produced by the curvature of spacetime.
