IO Framework The Interior Observer Framework

Independent cosmology · reproducible calculator · explicit claim labels

A black hole cosmology with zero fitted parameters. Try to break it.

The Interior Observer framework is built on two premises: the observable universe exists inside a Schwarzschild black hole, and physics inside the horizon equals physics outside. From those, geometry, BBN, recombination, and acoustic-scale observables follow with no fitted parameters. The calculator reproduces every published number. The reproducibility bundles let you rerun the scripts.

If the theory is correct, the math will just work.

Reproducibility

Immutable bundles for the claims most likely to be checked first

Each bundle is versioned to the paper, released under an immutable GitHub tag, pinned by SHA256, and built around a single validation command.

The values below are aligned to the active public calculator bundle and current paper scorecards. Status labels are intentionally not flattened to DERIVED.

Entry points

Three high-friction claims, stated with their boundaries

Cosmological Lithium in IO.

The lithium paper remains a scoped public authority, but the calculator BBN scorecard is under active re-derivation after the Q39 R_U/x update. The nuclear isovector transport ratio c_n/c_p = 1+γ² is preserved as a separate theorem-facing result.

Hubble Tension in IO.

The historical Hubble-ladder projection has been quarantined by Q45/Q46. The primitive observer projection is under active re-derivation before any Hubble-method row returns to the active Kerr scorecard.

Baryon Count from Horizon Topology.

IO derives the baryon-to-photon ratio to 0.8%, traced through thermal leptogenesis to a single topological datum on the horizon. The baryogenesis investigation is preserved as a registry: 48 theorem surfaces, 15 clean, 33 conditional-verified.

Bridge architecture

Three languages organize every crossing

Paper 33 — General Relativity and Quantum Mechanics Unified reframes the archive as three export languages, Paper 34 — The Hubble Tension Resolved closes the Hubble-method classification on top of that structure, and Paper 35 — Four Problems, One Horizon carries the four-problems confrontation across baryon counting, high-redshift galaxies, dark energy, and dark matter nulls. On this website, branch-sensitive numerics are aligned to the current public scorecards and reproducibility bundles rather than retired mixed-branch reconstructions.

Static Geometric Language

Always on. The boundary's quantum gauge algebra permanently imprints on the bulk's classical geometry.

  • Dark Energy Density
  • Baryon Fraction
  • Rosetta Identity
  • Observer Boundary

Dynamic Thermal Language

State-gated. Opens when the bulk process is thermally synchronized with the boundary.

  • FIRAS-fixed thermal readout
  • BBN Abundances
  • Spectral Index
  • Gravitational Slip

Fermionic Bridge

Density-gated. Opens when the bulk reaches Planck density. Boundary spinor data sources the torsion bounce.

  • Bounce Normalization
  • Onset Profile
  • Spin-Source Lift

Full-stack cosmology

The Complete Cosmic Lifecycle

Paper 32 — Closure: The Complete IO Framework anchors the active lifecycle statement. Recollapse is derived there, while bounce and restart remain DERIVED/CONDITIONAL_VERIFIED within the extended fermionic/chiral IO-EC completion.

Life

Active scoped observables carried

Expansion history, thermodynamics, BBN, perturbations, lensing, and late-time observables are carried across the public stack with explicit scope and claim labels.
