Abstract

We present Bowlin Interior Cosmology (BIC), a novel cosmological framework proposing that our observable universe exists within the interior of an accreting black hole. In this model, cosmic expansion emerges from the growth of the parent black hole's event horizon rather than from spatial expansion, with the Hubble parameter given by H = Ṁ/M, where M is the black hole mass and Ṁ is its accretion rate.

The model naturally produces H₀ = 73.5 km/s/Mpc from realistic black hole accretion histories, resolving the Hubble tension between SH0ES and Planck measurements. BIC resolves nine major cosmological anomalies using only five free parameters, with no requirement for exotic fields or undetected particles.

✅ JWST Early Galaxies: Enhanced structure formation at high-z
✅ S₈ Tension: Time-dependent torsion + merger viscosity
✅ Lithium-7 Problem: Orbital angular momentum coupling
✅ Bullet Cluster: Spin coherence mechanism
✅ Fine-Tuning: Cosmological natural selection

🚀 Interactive Cosmology Simulator

Adjust the parameters below to see how different accretion histories affect cosmic expansion. The simulation calculates H(z) using the BIC framework: H = Ṁ/M.

Loading Python engine (Pyodide)... This may take 10-15 seconds on first load.

Testable Predictions

Short-Term (6-12 months)

Test #1: Galaxy spin axes correlate with CMB "Axis of Evil" direction
Test #2: Orbital angular momentum dependence in nuclear abundances

Medium-Term (2027-2030)

Test #3: w(z) deviates from -1 (Euclid measurements)
Test #4: fσ₈(z) shows characteristic "kink" at z ≈ 0.6

Long-Term (2030+)

Test #5: High-ℓ CMB peaks show anharmonic drift
Test #6: Elliptical galaxies show spin-bias in velocity dispersion
