Gravity, energy conservation, and parameter values in collapse models

  • Philip Pearle

We interpret the probability rule of the CSL collapse theory to mean to mean that the scalar field which causes collapse is the gravitational curvature scalar with two sources, the expectation value of the mass density (smeared over the GRW scale a) and a white noise fluctuating source. We examine two models of the fluctuating source, monopole fluctuations and dipole fluctuations, and show that these correspond to two well-known CSL models. We relate the two GRW parameters of CSL to fundamental constants, and we explain the energy increase of particles due to collapse as arising from the loss of vacuum gravitational energy.

    This prescription is crude because it is based upon the undefined notion of measurement by an apparatus to determine which events can occur and upon the imprecise statement “after the measurement is completed” to indicate when the event and its accompanying collapse take place (note that the Born rule gives, not anabsolute probability per second of an event, but rather theconditional probability of an eventif one occurs). The currently fashionable “decoherence” schemes provide no essential improvement, possessing comparable undefined and imprecise features. See, e.g., F. Dowker and A. Kent,Phys. Rev.

    This energy gain is compensated by a loss of gravitational potential energy supplied by the vacuum. The appearance of, e.g., a Planck mass monopole means that the vacuum supplies both the Planck mass-energy and the (negative) monopole-particle mutual gravitational energy. The energy gain of a particle during its brief period of acceleration by the monopole comes from a decrease of this mutual gravitational energy. Thus, the subsequent absorption of the monopole by the vacuum entails a net loss of gravitational energy of the vacuum.Google Scholar
