A geometric look at the objective gravitational wave function reduction

Abstract

In ref [1], a criterion has been derived for the objective wave function reduction through the Shr\"odinger-Newton equation. In this paper, we shall derive that criterion by using the concept of Bohmian trajectories. This study has two consequences. First, providing a geometric perspective on the problem of wave function reduction and the other, representing the role of quantum force and gravitational force in the reduction process.
