Last year while thinking about it, I thought it will make more sense if we were pushed on our planet rather than being attracted to it. Mathematically, there is no change made to the current equation by reversing the force vector's direction! While I am read "Reinventing Gravity" from John W. Moffat. I learn that Mr. Georges-Louis Le Sage in 1758 was proposing particules could exert pressure on a body. However, they don't mention why the idea was later consider to be wrong by Maxwell and Poincaré? So, I am still not convince of the direction of the force? If we are push or attracted on Earth. If I consider gravity has a space deformation, maybe my question make no sense? Anyone could clarify it?
