What do you mean by "a geometric effect"? Einstein didn't like that notion but I'm very curious as to why most people who are fluent in GR do? Note my explicit mention of *modeled as* a geometric offect, the effect of course being the curvature of the manifold (spacetime) that we use as a stage to describe events. Dirk Vdm
