Cosmic curvature from de Sitter equilibrium cosmology

TL;DR

This paper demonstrates that de Sitter Equilibrium cosmology predicts observable curvature levels in the universe, which depend on matter and energy density ratios and initial conditions, providing testable predictions independent of inflation details.

Contribution

It introduces a model linking observable curvature to fundamental cosmological parameters within de Sitter Equilibrium cosmology, offering a way to test the theory through future measurements.

Findings

Predicts observable curvature levels in the universe.

Curvature depends on matter-to-energy density ratio and initial conditions.

Provides a testable link between cosmological parameters and early universe conditions.

Abstract

I show that the de Sitter Equilibrium cosmology generically predicts observable levels of curvature in the Universe today. The predicted value of the curvature depends only on the ratio of the density of non-relativistic matter to energy density in cosmological constant, and the value of the curvature from the initial bubble that starts the inflation. The result is independent of the scale of inflation, the shape of the potential during inflation, and many other details of the cosmology. Future cosmological measurements of the matter density, cosmological constant and curvature will open up a window on the very beginning of our Universe and offer an opportunity to support or falsify the de Sitter Equilibrium cosmology.
