The curvature of the water surface of the spinning bucket makes perfect sense to anyone in the bucket. It makes absolutely no sense to someone standing outside the bucket where you ask "rotation relative to what?"

You now need to make the rotation complicit to every body in the universe and those forces must transfer INSTANTLY no matter how far away the body is.

I believe in "Evil, Bad, Ungodly fantasy science and maths", so I am undoubtedly wrong to you.
