Derivation, Verification and Application of the Wave-Expansion Distance Formula — Wave-Expansion Cosmology Series Paper III, Argument Paper 1
Abstract
This paper is the third in the Wave-Expansion Cosmology series, Argument Paper 1. The fundamental proposition of wave-expansion cosmology is: space does not expand; waves expand by themselves during propagation.
We derive the complete frequency-difference distance formula from the physical laws of wave-expansion theory itself. The derivation proceeds in four steps. Step 1: define the evolution parameter Δτ = ln(v_emit / v_obs). Step 2: introduce the expansion rate K(Δτ) representing the distance increment per unit Δτ. Step 3: from the physical law that energy density decreases with spherical surface area and the wave-expansion driving force decays with energy density, derive K(Δτ) = K_0 * exp(β * Δτ) (physically β = 1). Step 4: integrate K(Δτ) to obtain D = K_0 * (1 - e^(-Δτ)).
We verify using 29 independent paired data points from NED-D geometric distances + SDSS raw observed frequency differences (completely no wavelength, completely no standard candles). At low Δτ, the result agrees with the linear form, giving K_0 = 143.17 billion light-years. For a source with frequency-difference ratio corresponding to z = 14.4, the distance is 133.87 billion light-years. We derive the cosmic age from the CMB: Δτ_CMB = 7.004, corresponding to a wave-expansion distance of 143.04 billion years.
We provide the complete derivation, data sources, code, reproduction steps, and application guide for all researchers to verify and apply.
