What the above demonstrates is that the spatial deflection, 2GM/Rc^2,
In fact it easily demonstrated with the straight flight path, gravity
free, tangent intersecting with the eye of the observer tangent, that
spatial deflection measured in terms of radius causes an angular
deflection of twice that. R=2R as you might say. The mathematics of
gravity has not broken down. It was the wrong formula in the first
place. A simple piece of Euclidean logic was all that was needed to
show that 4GM/Rc^2 was the right formula for anglular deflection and
2GM/Rc^2 the right formula for spatial deflection.
