This volume establishes the first formal falsification program of EL Science through pre-registered predictions and direct kill-tests against observational cosmology. Unlike earlier volumes focused on framework construction and phenomenological viability, this work freezes the model’s predicted deviations from ΛCDM in advance and attempts to refute them using every currently accessible low-cost test available without a Boltzmann solver. Three frozen predictions are committed before future survey results: a percent-level H(z) excess peaking near z≈0.58, a non-monotonic vacuum-density evolution with an interior maximum near z≈0.85, and a phantom-crossing dark-energy equation of state evolving dynamically with redshift. These predictions are tested through Planck CMB distance-prior geometry, the Ωm–H0 consistency triangle using BAO and cosmic chronometers, and an analytic integrated Sachs–Wolfe direction estimate. The framework survives the available tests while honestly documenting its limitations and remaining open challenges. The CMB geometry and internal consistency triangle are successfully reproduced, while the ISW analysis reveals a mild but explicitly acknowledged concern regarding the low-ℓ anomaly direction. The volume clearly distinguishes between currently surviving tests and decisive future tests requiring full CAMB/CLASS Boltzmann analysis and Big-Bang nucleosynthesis computations. This work transforms EL Science from a purely viable alternative cosmology into a framework with explicitly stated refutation conditions, frozen observational signatures, and forward-looking falsifiability criteria tied directly to upcoming DESI and Euclid precision measurements.
