Abstract

The Diosi-Penrose model of quantum-classical boundary postulates gravity-related spontaneous wave function collapse of massive degrees of freedom. The decoherence effects of the collapses are in principle detectable if not masked by the overwhelming environmental decoherence. But the DP (or any other, like GRW, CSL) spontaneous collapses are not detectable themselves, they are merely the redundant formalism of spontaneous decoherence. To let DP collapses become testable physics, recently we extended the DP model and proposed that DP collapses are responsible for the emergence of the Newton gravitational force between massive objects. We identified the collapse rate, possibly of the order of 1/ms, with the rate of emergence of the Newton force. A simple heuristic emergence (delay) time was added to the Newton law of gravity. This non-relativistic delay is in peaceful coexistence with Einstein’s relativistic theory of gravitation, at least no experimental evidence has so far surfaced against it. We derive new predictions of such a ‘lazy’ Newton law that will enable decisive laboratory tests with available technologies. The simple equation of ’lazy’ Newton law deserves theoretical and experimental studies in itself, independently of the underlying quantum foundational considerations.
