Replacement of Space-Time with Superfluid Space and Restoration of Newton’s Dynamic Ether

Although it has been approximately 80 years since the graviton was theoretically predicted, it has not yet been discovered. To resolve this puzzle, this study developed a model wherein the gravitational force is incorporated into the fundamental structure of the universal space. A physical object diminishes the energy density of space exactly by the amount of energy it contains. The resulting area of space with a diminished energy density is pushed in the direction of the closest area with the lowest energy density. A physical object situated in the corresponding space with a lower energy density follows the motion of this area towards the closest area with the lowest energy density. Therefore, there is no direct gravitational force between the physical objects and gravity is incorporated into the variable energy density of the space. This model of gravity has advanced Newton’s ether model with the extension of the mass-energy equivalence principle to space and works without the hypothetical graviton.
