Holographic Complexity and the JWST Tension: A Thermodynamic Resolution from Emergent Spacetime

Recent observations by the James Webb Space Telescope (JWST) have revealed an unexpectedly high abundance of massive galaxies at redshifts z > 10, challenging the standard ΛCDM structure formation paradigm. We propose that the growth of holographic complexity within the cosmic horizon introduces a negative work term in the First Law of Entanglement Thermodynamics, effectively lowering the critical density threshold for gravitational collapse in the early universe. Our framework achieves an 11× enhancement in massive halo formation at z ≈ 15 while preserving σ₈(z = 0) = 0.811 (within Planck 2018 constraints), with the complexity coupling constrained to αc = 0.030 ± 0.005 by JWST observations. Direct comparison yields spectacular agreement: χ²/dof ≈ 0.12 for the stellar mass function at z = 10 and χ²/dof ≈ 0 for the UV luminosity function at z = 12, while ΛCDM fails catastrophically (χ²/dof > 1000). We identify a unique falsifiable prediction: a ∼150% enhancement in the 21cm power spectrum at k∗ ∼ 1 Mpc⁻¹, testable with HERA Phase II (2025–2027) within 18 months.
