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.

based on the new discovery of moving photon do create force and a formula of describe this new discovery: Applying this discovery from the micro world to the macro world, show that from atomic world to the galaxy world, the nature has been working obeys this law, and their actions can all be described by this formula. The Coulomb law and Newton law of university gravitation are only calculation formula in the specific condition status.

Since electron has been discovered, people have been thinking it possess one electric charge, the nuclear possess contrary charge. Based on the provided new discovery that moving photons do create force, I have calculated the number Z of elements, discovered that the number Z of elements can be calculated by frequency of x-ray, and the atomic weight can also be calculated by frequency of x-ray. This method of calculated way shows the essence of electric charge, and shows the essence of gravitational mass, from this way, here in first time provide one way show the unification of gravitation and electromagnetic force.

In the process of exploring the essence of light, Newton initially agreed with the particle interpretation of light while Huygens argued for the wave theory. Hence, these two theories had been disputed in Newton’s time. In the beginning people accepted the particle theory, but after Thomas Young’s experiment and Augustin Jean Fresnel’s experiment, people began to accept the wave theory. Until Einstein proposed the quanta concept, which was later called photon, and, even later, De Broglie proposed the wave nature of matter, subsequently, people began using particle-wave duality to explicate all phenomena in micro world. Thus here appears a paradox: how can one particle exist in two forms? To solve this enigma, I have done some experiments; discover that moving photons create force; this effect reveal the phenomenon of light wave property - the inference fringes is caused by force which moving photons produced. The essence of light is particle but not particle-wave duality.

More than three hundred years ago: Newton thought that the reason of apple falling was due to gravity, although he discovered the gravity in the earth, he did not know what how produce gravitation; he said that God is the first driving force. From then on, more than three centuries have passed many people had been exploring the origin of gravitation, until today people have no notion on the origin of gravitation. In order to find the origin of gravitation, I did some experiments and discovered that moving photons generate gravitation. This discovery come to light the origin of gravitation: applying this discovery to others particles show the same effects; in the same time these discoveries have been applied in macro world to calculate the acceleration of gravity, first time display the more accurately formula than Universal law of gravitation to describe the gravity field of earth. These works indicate that moving elementary particles bring on interaction force which appearing behavior of gravitation in the macro world. This show that these discoveries reveal the essence of Universal law of gravitation from micro world to macro world, and reveal the origin of gravitation: namely, tell us where gravitation come from, and solve the enigmas what Universal law of gravitation cannot solve until today.
