First of all, this book doesn't contain any complex formulas or obscure technical terms, and anyone who can read all can understand its content. Since Newtonian mechanics was first established, there was a question still unresolved, that just, what is the medium through which gravitation is transmitted? Newton was limited by the experimental techniques of his time, so could only simply attribute gravitation to the action at a distance. But in his letter to Bentley, he expressed questions about his own assumption. Even today, schools only tell everyone that, scores can be obtained using formulas, if you don't understand, just use formulas. When quantum mechanics was first established, Einstein simply attributed the gravitational force of the universe to the curvature of spacetime, and replaced the interaction forces between particles with various obscure mathematical tools. People focus on the study of laws, but their understanding of the forces in macro and micro fields, has always been vague. Including the formation of black holes, people also simply attribute it to the collapse of gravitation, the collapse of spacetime, and other idealistic speculations. However, we must remember that, time and space, do not exist in nature itself. Time and space, are just mathematical tools created by the human spirit. Before starting the detailed reasoning, I would like to summarize my conclusions briefly at the beginning. They are all based on nature and reality, all based on the latest observational data and experimental results. First, black hole is composed of matter. All black holes in the universe, are not formed by space collapse or gravitation collapse, but by moving fluid matter that filled in the universe. Any theories related to the curvature of time and space, only partly held true on the surface laws, but they are fundamentally untenable and contrary to the nature and reality. Because the terms time and space are just spiritual concepts, they are not material entities, and cannot be mechanically applied with the physical dynamic properties that only matter possesses. Second, the universal gravitation, is formed by the motion of the fluid matter. The gravitation of all stars in the universe, is not generated by any star itself, but by the motion of the fluid matter filled with universal space, and the fluid pressure generating on every star. The magnetic fields of stars, planets, magnets, and electromagnets, are all composed of this particle fluid substance. All stars and stellar cores, only have some impacts on the fluid gravitational field of themselves, but any stellar core and any star themselves, are not the sources of gravitation. Light, is the phenomenon of the matter’s transforming energy acting on the particles of the cosmic fluid. And electromagnetic waves, are the particle vibration waves of the cosmic fluid. This is a brand new view of spacetime, as well as a new theory for reconstructing and uniting quantum mechanics and classical mechanics, and also the formation process and preservation methods of antimatter.
