This preprint presents the Ultronic Medium Hypothesis (UMH) cosmological validation study, comparing UMH-based dynamic-strain simulations to ΛCDM predictions using the Pantheon+ supernova dataset. Results show quantitative agreement with observed distance–redshift curves without invoking dark energy. The UMH framework models spacetime and matter as emergent from strain-wave dynamics in a continuous medium. All data and simulation code are openly available for replication.
