An Alternative to the General Theory of Relativity

This is the third of three related works on dark matter (DM), dark energy (DE), and the General Theory of Relativity (GTR). In the first two papers laws L1 and L2 are given which resolve the DM and DE problems, respectively, without the invention of mysterious dark forces. While L1 deals with the gravitational force that one moving body of mass M exerts on another moving body of mass m, in this third work it is extended to L3 to include the effects of gravity on photons and bodies moving with unusually high speeds. From L3 many of the well-known triumphs of GTR are given alternate explanations. Based on the inability of GTR to explain DM and DE, and also from other arguments provided herein, it is concluded that GTR is either incomplete or in error.
