In the Physical Sea model, "Dark Matter" is not an invisible particle but an emergent property of the Vorticity (∇ × v ∇ × v of the medium. Galaxies are vortices within the Sea, where the rotating medium "drags" matter along with it.
The observed rotation velocity V o b s V o b s V g r a v V g r a v V s e a V s e a
V o b s = V g r a v + ( ∇ × v ) ⋅ R V o b s = V g r a v + ( ∇ × v ) ⋅ R
Where v v R R
Unlike the Newtonian prediction that V g r a v ∝ 1 / R V g r a v ∝ 1 / R
As V g r a v V g r a v ( ∇ × v ) ( ∇ × v )
V r o t ≈ Constant at large R V r o t ≈ Constant at large R
This "carrying" effect prevents the star from flying off, matching the observed "flat" rotation curves without the need for additional mass.
Gravitational Lensing (Refractive): The rotating Sea causes extra bending of light due to its motion (frame-dragging at a cosmological scale).Galactic Collisions: Galaxy mergers are better modeled as two merging fluid vortices rather than purely ballistic mass interactions.Pulsar Drag: High-speed rotating neutron stars (pulsars) experience viscous drag against the Sea, which can be measured through timing variations.
