New Einstein Field Equation Explain of Structure of Fluid

In fluid, we need to reconsider the relationship among the center of gravity, the center of buoyancy, the mass center, and the center of structure (center of form). We cannot use Einstein equation to study the gravity structure of the fluid. We must advance Einstein equation, get a negative Einstein field equation and negative gravitational structure, study a fluidic gravitational structure (which is from temperature, heat, humidity, pressure, buoyancy, and fluid resistance), and explain of fluidic gravitational structure which has more density of negative gravitational structure. It also can study vortex and turbulence which have structures of spacetime center.
