So, it would seem that Newton's theories of gravity predict correct results but are not rooted in reality. The earth is not attracted to the sun via gravity, both warp the space (spacetime) around each other and travel in the lines of force that this warping generates (this seems to imply that gravity if just momentum acting along a line of force - is this a reasonable conclusion).

It could be argued that Newtons laws are digital simulations of the spacetime continuum and ditto for quantum theory. Possibly even these simulations also take place in our minds (and therefore that our minds are outside spacetime). A continuum, of course, can be approximated by splitting it up into points. The smaller the points, the closer the approximation.
