General Relativity Must Be Used for Which Frame of Reference

Special relativity applies to special cases its mostly used when discussing huge energies ultra-fast speeds and astronomical distances all without the complications of gravityEinstein. The special principle of relativity states that physical laws should be the same in every inertial frame of reference but that they may vary across non-inertial onesThis principle is used in both Newtonian mechanics and the theory of special relativityIts influence in the latter is so strong that Max Planck named the theory after. Relativity The cone shape emerges since all light must reach the same distance from the point at a given time no matter its direction. . General relativity states that planets bend space and time the way a bowling ball bends a trampoline. Along with all paths taken by the light reaching the point as the flash occurs. Thus for example the path of a planet orbiting around a star is the projection of a geodesic of the curved 4-dimensi...
