Emergent gravity at all scales

TL;DR

This paper demonstrates that the entire observed gravitational potential across all scales can be derived from a specific quantum wavefunction, suggesting gravity may emerge from quantum mechanics.

Contribution

It provides a concrete example of how the gravitational potential at all scales can be generated by an underlying wavefunction, linking quantum mechanics to gravity.

Findings

The gravitational potential from planetary to cosmological scales can be produced by a suitable wavefunction.

Quantum mechanics can generate observed gravitational interactions at all length scales.

Implications for understanding gravity as an emergent phenomenon from quantum states.

Abstract

It has recently been shown that any observed potential can in principle be generated via quantum mechanics using a suitable wavefunction. In this work, we consider the concrete example of the gravitational potential experienced by a test particle at length scales spanning from the planetary to the cosmological, and determine the wavefunction that would produce it as its quantum potential. In other words, the observed gravitational interaction at all length scales can be generated by an underlying wavefunction. We discuss the implications of our result.
