# A model of quantum collapse induced by gravity

## TL;DR

This paper proposes a gravity-induced quantum collapse model where classical gravity interacts with quantum systems, predicting rapid collapse of macroscopic superpositions without introducing new fundamental constants.

## Contribution

It introduces a novel model coupling quantum wave functions with Bohmian particle positions via a modified gravitational interaction, leading to spontaneous collapse.

## Key findings

- Predicts extremely small effects on microscopic systems
- Fast collapse of macroscopic superpositions proportional to size^5
- No new fundamental constants required

## Abstract

We discuss a model where a spontaneous quantum collapse is induced by the gravitational interaction, treated classically. Its dynamics couples the standard wave function of a system with the Bohmian positions of its particles, which are considered as the only source of the gravitational attraction. The collapse is obtained by adding a small imaginary component to the gravitational coupling. It predicts extremely small perturbations of microscopic systems, but very fast collapse of QSMDS (quantum superpositions of macroscopically distinct quantum states) of a solid object, varying as the fifth power of its size. The model does not require adding any dimensional constant to those of standard physics.
