    • A few years ago, when I told Renata Grassi about my attempts at this formalism, she suggested that it might be worthwhile to try again to couple (Formula presented) to the nucleon number density directly, without the intermediacy of the (Formula presented) particle. At the time we did not appreciate that the two models could be equivalent in the sense shown here

    • Long before this calculation was possible, Renata Grassi (private communication) argued that, since one would expect the radiation rate of an atom due to excitation by collapse (calculated by nonrelativistic CSL) to be time dilated when the atom is moving, one could conclude that the collapse rate itself ought to suffer time dilation. Our calculation shows that this is so for a single particle. If this is also so for a macro-object, one would have the persistence of a superposition of its spatially separated states in a frame relative to which it is moving close to the speed of light (of course, observation of its state by another macro-object at rest would rapidly collapse the state vector in that frame)
