Quantum Potential and Cosmological Singularities

TL;DR

This paper explores how the de Broglie-Bohm interpretation applied to quantum cosmology suggests that quantum potential effects can prevent the traditional initial and final singularities in the universe.

Contribution

It introduces a novel application of the de Broglie-Bohm interpretation to the Wheeler-DeWitt equation in quantum cosmology, showing potential avoidance of singularities.

Findings

Quantum potential dominated solutions avoid cosmological singularities

Quantum effects may alter the nature of the universe's beginning and end

Back-reaction of geometry and matter fields influences cosmological evolution

Abstract

We apply the de Broglie-Bohm interpretation to the Wheeler-DeWitt equation for the quantum FRW cosmological model with a minimal massless scalar field. We find that the quantum FRW cosmological model has quantum potential dominated solutions that avoid the initial and the final cosmological singularities. It is suggested that the quantum potential and the back-reaction of geometry and matter fields may change the property of the cosmological singularities of the Universe.
