Hydrodynamic Interpretation of Gravity: Predicting the Position of Planet 9 via the v_L Model.

Description / Abstract This publication presents a novel hydrodynamic interpretation of gravity, framing gravitational interaction not as static spacetime curvature, but as a dynamic process of space absorption by mass. Central to this theory is the Local Space Velocity ($v_L$) model, which defines gravity as a medium flow ("suction") towards a central mass. Key highlights of the research: Theoretical Framework: The model introduces the $v_L$ formula, successfully deriving Kepler’s Third Law and establishing a direct link between space flow velocity and orbital tangential velocity. Relativistic Verification: By introducing the concept of "twisted space viscosity," the model accounts for relativistic effects with high precision, matching observed data for Mercury’s perihelion precession (42.95"), gravitational lensing (1.75"), and the Shapiro delay (~220 μs). Predictive Power: The $v_L$ model identifies a "sink vector" deficit in the motion of Trans-Neptunian Objects (TNOs), leading to the prediction of Planet Nine (Artem's Planet). Predicted Parameters for Planet Nine: Mass: 6.0 – 6.4 $M_\oplus$ Distance: 450 – 500 AU Location: Taurus/Orion sector (RA: 04h 30m; Dec: +15°). The detection of this celestial body would provide empirical evidence for the hydrodynamic nature of gravity, shifting the paradigm of modern astrophysics.
