Nature abhors macroscopic superpositions

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.
