I'm hoping for some help in understanding how the Michelson-Gale-Pearson experiment in 1925 is held as a refutation of the Stokes-Planck theory of gravitational aether drag. If I understand the Stokes-Planck theory correctly, complete dragging of the aether near a sufficiently massive body (diminishing at distance, in accordance to the inverse square law as it applies to gravitational force) would be essentially indistinguishable from a complete dragging model. Wouldn't it also be indistinguishable from a non-aetheric model? Didn't Michelson-Gale-Pearson support that? What am I missing? Thanks.
