Nature abhors macroscopic superpositions

TL;DR

The paper argues that macroscopic mass superpositions are naturally suppressed due to an energy dip, which acts as a force preventing their formation, with implications for the measurement problem.

Contribution

It introduces a model showing a natural energy-based reluctance for macroscopic superpositions, linking quantum superpositions to spacetime geometry.

Findings

Energy dip in superpositions prevents macroscopic superposition formation

Reluctance manifests as an energy minimum at specific separation distances

Implications for understanding the measurement problem in quantum mechanics

Abstract

Superpositions of mass distributions can potentially lead to entanglement with the geometry of spacetime. Here we show that there exists a natural reluctance for macroscopic mass distributions to form such superpositions. The macroscopic superposition is modeled as a Schr{\"o}dinger cat state. The reluctance manifests as a dip in the total energy of the Schr{\"o}dinger cat state as a function of the separation distance between the terms in the superposition. The dip in the energy provides an opposing force preventing the formation of the superposition. A generalization of this phenomenon addressing the measurement problem is also discussed.
