Cosmic curvature from de Sitter equilibrium cosmology

Understand

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.
