Gravitation and the noise needed in objective reduction models

Abstract

I briefly recall intersections of my research interests with those of John Bell. I then argue that the noise needed in theories of objective state vector reduction most likely comes from a fluctuating complex part in the classical spacetime metric, that is, state vector reduction is driven by {\it complex number valued} "spacetime foam".

Essay for the John Bell anthology being assembled by Mary Bell and Shan Gao; 11 pages; v2 has changes in the discussion of the Diosi-Penrose proposal, and an added reference; v3 incorporates corrections to the index structure in Eq.(6); v5 has an added Appendix and reformatted references and an alternative correction to indices in Eq. (6). v5 corresponds to the anthology version
