Again: if the force of the cosmos is greater than the force of the Earth on a positive charge (which is what you're saying) then the polarisation is in the opposite direction.

And that's ignoring that you're suggesting that a polarisation on the scale of 1 × 10−10m would have a significant effect for objects that are more than 6.4 x 106m from the COM of the Earth and 4 x 1016m from the nearest star, that would be the nearest object in the "cosmos" that could be exerting this repulsive downward force.
