> to deriving then proving experimentally proving general relativity and decomposing GR into Newtonian physics/other laws of electromagnetism Do you mean Special Relativity, which covers classical mechanics and electromagnetism? General Relativity covers gravitation and cosmology without electromagnetism (though Kaluza and later Klein devised a theory unifying gravity and electromagnetism by adding an fifth dimension to General Relativity, which can then be decomposed into 4-dimensional GR and Maxwell's equations).
