Dark matter is a physical phenomenon lacking in the calculation of gravity

Dark matter is the universal gravitation "formed" by the absence of gravity in three-dimensional space acting through the surface of the sphere. The surface area formula of the sphere is: S=4 p R ^ 2, the mass is certain, and 4 p is a constant, which is the essential reason why the size of gravity is inversely proportional to the square of the radius. Divide the gravitation of the law of universal gravitation by 4 p R, and the gravitation changes into the gravitation of one-dimensional space: so the expression of the law of universal gravitation in one-dimensional space: F1=GMm/4 p R ^ 3 - (2); The volume formula of the sphere: V=4 p r ^ 3/3. It can be said that the gravitation of one dimension space is obtained by dividing the two-dimensional space gravitation by 4 p R. According to scientific reasoning, the gravitation of three dimensions space should be obtained by multiplying the two-dimensional space gravitation by R/3. Therefore, F3=GMm/3R - (4), (1), (4), and the solution is F3=F2R/3, which can be further simplified to F3/F2R=1/3 - (5). This is the proportion of the mass of matter and dark matter in the three-dimensional space in the formal universe. Its essence is still matter, which is the result of the artificial lack of calculation of gravity. Therefore, it is not so much dark matter as gravity.
