TL;DR
This paper explores the quantum origin of a hot universe, explaining CMB anisotropy through quantum cosmology and analyzing the probability of universe creation from a GUT-scale false vacuum.
Contribution
It introduces a quantum cosmological model that accounts for universe birth probabilities and explains CMB anisotropy within a minisuperspace framework.
Findings
Universe's energy spectrum explains CMB anisotropy
Probability of universe birth is about 10^{-10^{14}}
Open, flat, and closed universes can originate with matter having negative pressure
Abstract
We consider quantum birth of a hot Universe in the framework of quantum qeometrodynamics in the minisuperspace model. The energy spectrum of the Universe in the pre-de-Sitter domain naturally explains the cosmic microwave background (CMB) anisotropy. The false vacuum where the Universe tunnels from the pre-de-Sitter domain is assumed to be of a Grand Unification Theory (GUT) scale. The probability of the birth of a hot Universe from a quantum level proves to be about . In the presence of matter with a negative pressure (quintessence) it is possible for open and flat universes to be born as well as closed ones.
