Unification of gravitation and electromagnetic force (Third Portion)

 According to new discovery of law of moving photon does create force, we can know the reason why the photon become to electron-positron pair and can get that the elementary particle in Nature is photon, from this we can know the basic composition of matter is photon, in other words: the matter of producing gravitation and electromagnetic force is based on the same matter: photon. Meanwhile here show the Millikan's elementary charge is not universal law, reveal the essence of matter wave is due to force.
