Nobody is suggesting to use an effective dipole charge and 1/r^2 to calculate dipole gravity between two bodies, because the effective dipole charge varies with angle and distance. That's why Coulombs law in vector form and at long distances approaches 1/r^3. I am using Coulomb's law and 1/r^2 at short distances and on individual coulomb force vectors to show that there is always a net attractive coulomb force between two bodies.querious wrote: ...
That is one mathematically indisputable form of gravity whether you use r^2 or r^2½ or r^3.
Is there an additional form of gravity ?
The effective charge of each hydrogen dipole 10^-10 m apart is only 9.000*10^-19 of an elementary charge. The amount of skinn that dipoles show each other is consequently extremely small.
The question is no longer whether coulomb attraction causes (part of) gravity.
Challenge 1 is now to test and confirm how much effective skinn charge two bodies show each other and to compare the attraction caused by this to the standard Newton mass method of calculating gravity.
Challenge 2 is to figure out how this, and much else, is communicated through space.
