Implications of a Quantum Mechanical Treatment of the Universe

TL;DR

This paper applies quantum mechanics to model the early Universe, suggesting it avoids initial singularity, expands, and resolves causality issues through a wave packet approach and the correspondence principle.

Contribution

It introduces a quantum mechanical framework for the early Universe, linking the scale factor to wave packet width and addressing key cosmological problems.

Findings

No initial singularity in the quantum model

Universe expansion derived from quantum principles

Causality problem of the standard model is resolved

Abstract

We attempt to treat the very early Universe according to quantum mechanics. Identifying the scale factor of the Universe with the width of the wave packet associated with it, we show that there cannot be an initial singularity and that the Universe expands. Invoking the correspondence principle, we obtain the scale factor of the Universe and demonstrate that the causality problem of the standard model is solved.
