A simple quantum cosmology

TL;DR

This paper presents a simple quantum cosmology model based on Friedmann equations, quantum mechanics, and experimental constants, explaining universe creation without singularities and aligning with observed cosmological parameters.

Contribution

It introduces a novel model of universe origin with N > 6 dimensions, where the compact dimensions' potential leads to inflation and matches current cosmological observations.

Findings

Universe inflates by about 26 orders of magnitude

Model predicts Omega_Lambda ≈ 0.68

Universe created from nothing with zero total energy

Abstract

A simple and surprisingly realistic model of the origin of the universe can be developed using the Friedmann equation from general relativity, elementary quantum mechanics, and the experimental values of h, c, G and the proton mass. The model assumes there are N space dimensions (with N > 6) and the potential constraining the radius r of the invisible N -3 compact dimensions varies as r^4. In this model, the universe has zero total energy and is created from nothing. There is no initial singularity. If space-time is eleven dimensional, as required by M theory, the scalar field corresponding to the size of the compact dimensions inflates the universe by about 26 orders of magnitude (60 e-folds). If the Hubble constant is 65 km/sec Mpc, the energy density of the scalar field after inflation results in Omega-sub-Lambda = 0.68, in agreement with recent astrophysical observations.
