MOND might be several phenomena including multipole gravitational potential flows near the speed of light
https://en.wikipedia.org/wiki/Modified_Newtonian_dynamics Their a0 is 1.2E-10 meter/second^2 which is the sensitivity needed to follow the sun moon tidal gravity signal at the earth’s surface. Potential changes at the sun and moon (and on earth) “diffuse” at the speed of light and change the local gradients. Also, electrons and protons from suns – a few charges easily
