Interpretation of Gravity and Interactions by Entropy

The purpose of this research is to provide models that interpret gravity and interactions by entropy. We introduce D+-division partial entropy by applying ideas of the logistic function to its entropy and define the inverse of D+-division partial entropy as the gravitational potential. By applying these concepts, we attempt to explain as follows: 1) Gravity becomes a constant value within small distances under specific conditions. Gravity may have 5-states within small enough distances. There may exist anti-gravity which is the opposite of Newton’s gravity among 5-states. Furthermore, the gravitational potential and the Coulomb potential can be treated similarly within small distances. 2) The rotation speed of the galaxy does not depend on its radius if the radius is within the size level of the universe. 3) The gravitational acceleration toward the center may fluctuate at long distance compared to Newton’s gravity. These become the extension of Newton’s gravity and suggest that there may exist constants that control gravity and the speed of galaxies. Besides, it describes the relationship between the Yukawa type potential and D--division partial entropy with negative. We attempt to suggest 11-types interactions including the gravitational acceleration g and compare the ratios of fundamental 4-interactions in nature using suggested equations. Furthermore, we mention that the relationship with entropic gravity, that the possibility of existence new interactions, and that the gravitational constant G can fluctuate if entropy changes. Gravity and electromagnetic and quantum may unify through entropy.
