We show that within the framework of a definite proposal for the initial conditions for the universe, the Hartle-Hawking `no boundary' proposal, open inflation is generic and does not require any special properties of the inflaton potential. In the simplest inflationary models, the semiclassical approximation to the Euclidean path integral and a minimal anthropic condition lead to $\Omega_0\approx 0.01$. This number may be increased in models with more fields or extra dimensions.

  1. Morse-Bott inequalities, Topology Change and Cobordisms to Nothing

    hep-th 2024-10 unverdicted novelty 6.0

    Morse-Bott inequalities yield homology bounds and topology-change counts for generic cobordisms to nothing in string theory compactifications.

  2. Inflation, Open Universes, and Dark Energy

    astro-ph.CO 2026-07 conditional novelty 5.0

    A slightly open universe with Ω_k ≈ 3×10^{-3} pulls n_s down to ~0.969, reconciling plateau inflation models with combined CMB and DESI data.

  3. Inflation from a Weyl-flat null origin

    hep-ph 2026-04 unverdicted novelty 5.0

    Single-field inflation with ε(N) approaching a constant in (0,1) at early times forms an asymptotic universality class with a Weyl-flat null origin while producing ns and r values compatible with Planck data.
