Abstract: The structures of Photon, Higgs Boson, Electron, and Positron are proposed based on “Wu’s Particle”, a Yangton and Yington circulating pair. Gravitational Force is generated by the attractive force through close contact between two Higgs Bosons of String Structures made of “Wu’s Particles” having the same circulation direction. Electrical Forces are formed by either attractive or repulsive forces via close contact between Electrons and Positions/Protons. Higgs Boson Radiation and Electron Radiation with Inverse Square Law and Contact Interactions, defined as “Particle Radiation and Interaction Theory”, are proposed as the mechanisms to explain Newton’s Law of Universal Gravitation and Coulomb’s Law of Electrical Forces. Furthermore, Gravitational Waves instead of ripples of space-time, are in fact the fluctuation of the total Gravitational Forces of two merging Black Holes detected in Line of Sight by Earth observers. This can be interpreted by Higgs Boson Radiation and Interaction Theory based on Yangton & Yington Theory.Abstract: The structures of Photon, Higgs Boson, Electron, and Positron are proposed based on “Wu’s Particle”, a Yangton and Yington circulating pair.
