The Unwarranted Assumption of Zero Magnetic Redshift: How the Consensus Overestimates Cosmological Expansion by Ignoring Critical Ionization Velocity and Collective Plasma Effects in High-Redshift Galaxies — With a Specific Re-analysis of MoM-z14 (z = 14.44)

The standard cosmological model (ΛCDM) interprets the observed redshift of distant galaxies as a purely cosmological phenomenon. This interpretation rests on a single, critical assumption: that the magnetic contribution to the total observed redshift is exactly zero (z_mag = 0). We demonstrate that this assumption is both unwarranted and quantitatively consequential. Using the Al-Mahaqari Magnetic Redshift Equation (z_mag = eBλ₀/4πmₑc²), we show that for a galaxy with a magnetic field of B ∼ 10⁻⁴ T, the magnetic redshift contribution to z = 14.44 is z_mag ≈ 2.88, representing 20% of the total. We provide a specific, detailed re-analysis of the MoM-z14 discovery paper, identifying five unexamined systematics. We further incorporate the author's independent calculation of the age of the universe as t₀ = 14.90 ± 0.12 Gyr—over a billion years older than the standard ΛCDM value of 13.8 Gyr. A complete Python simulation accompanies this paper.
