You're begging the question. The premise that gravity comes from several directions is retarded.   

You just repeat your unfounded claim. I had asked you to explain how and why. But you're too retarded to even follow the flow of comments.

I think CI readers comprehend that you're not able to substantiate your claims. Your line of argumentation is well known on CI. It has been "Railroad tracks are adaptable to any curvature of terrain, but not to that most slight curvature of the round earth". It now is "gravity comes from several directions is retarded". No reasons given, even after request.

The direction of gravity on earth is always vertical. But generally it just acts as a force, so it could come from multiple - any - direction (and even multiple at the same time, water being attracted the earth but also attracted by the moon, creating tides, shows exactly that).

But yes, plumb lines are not always straight in geodesy.
