Pressure gravity also explained by the space curvature of the 6-hour Tides even at the poles.

Pressure gravity also explained by the Tides, by the SPACE CURVATURE RING pressing the water extra down around the world, perpendicular to the axis on the Moon.
However, Due to the space curvature ring around the earth, there is only ebb but no flow at the poles, because of the absence of the moon pressure reduction on the water, which is located around the equator with minimal rising water influence at the poles leading to anomalies.

(“The Speed of Gravity – What the Experiments Say” , Tom Van Flandern, Physics Letters A, 250 (1-3) (1998) pp. 1-11) SEE: " Laboratory, solar system, and astrophysical experiments for the “speed of gravity” yield a lower limit of 2 × 1010c. The link between relativity and the causality principle involves issues of the meaning of gravitational waves and curved space-time analogies. Apparently, Lorentzian relativity better describes nature than special relativity."

Conclusion: Tom van Flandern was half right (according to Q-FFF Theory).

Q-FFF Theory says:  the gravitational solar well is created by the Fermion pushing Axion oscillating vacuum lattice focused on the sun and mainly absorbed by both SABHs with the sun located in the middle.

In other words, The vacuum based gravity pressure on the sun is instant (like a gravity well) because guided by the dual polar solar SABHs system (the former Herbig Haro dual black holes star forming system).

However the smaller numbers of left over vacuum strings, coming out of the sun after bouncing with the sun's Fermions and transfer into all eigenvalues of gluons/ photons, etc,   will show the local speed of light., which is still a support for Tom van Flandern's ideas, if gravity is a pressure force..
