A unified theory of physics has been evasive, I believe, because physicists have only considered a continuum of unification. In other words, we have attempted to relate all spacetime to all quantum dynamics - that they are inclusively connected. Has the argument arisen that quantum measurement corresponds only to discrete points in spacetime, not joined overall as a continuum? Wavefunction collapse might occur, say, at a singularity unique to a spacetime neighborhood, perhaps corresponding to the intersection of geodesics. Do you think that partial connectiveness between spacetime and quantum measurement is fundamental to the unification of physics?.
