i never asked for opinions.
just answers, if you don't want to answer, then press the back button, thanks.

My understanding of Newtonian gravity is that every massive object creates a force vector field that exerts a force on every other massive object. I also understand that the Newtonian gravity model creates the same acceleration on another massive object regardless of its mass.

My understanding of relativistic gravity is much more limited although I do believe it is a curvature of the space-time by massive objects. Objects apear to be 'attracted' to the massive object when really they are travelling along the curved 3d surface of 4d spacetime.

So my question is, how do both of these models of gravity how certain things which are lighter than the medium they are in float. For example, a cork floats in water and helium floats in air. Should the earth not still produce a force on these objects and pull them to the earth?

Thanks.
