Recent stringent observations of the declining accelerated expansion of the universe (DES Collaboration 2025, arXiv:2503.06712) now challenge even more authoritatively the concordance ΛCDM paradigm with its ad hoc cosmological constant. Yet, this phenomenon had already been quantitatively predicted by T. Yarman via his Rest-Mass Dynamics (RMD) decades ago (Ann. Fond. de Broglie 2004, 29, 45; Eur. Phys. J. Plus 2013, 128, 8; Ann. Phys. 2023, 454, 16934). The framework spearheaded by the first co-author is grounded in strict energy conservation and is fully compliant with both Quantum Mechanics (QM) and Special Theory of Relativity (STR). RMD thus naturally explains i) the observed acceleration magnitude (~10^-10 m/s^2), ii) its 1/r^2 decay behavior, and iii) key cosmological data such as Cosmic Microwave Background (CMB) anisotropies, the so-called Baryon Acoustic Oscillations (BAO), and the securely established Hubble tension without invoking Dark Energy. Yarman et al.’s theoretical enterprise replaces spacetime curvature with a dynamic rest-mass scaling formalism that leads to the centennially verified results, such as gravitational redshift and bound muon decay-rate retardation (Int. J. Theor. Phys. 2011, 50, 1407). Besides these, it accounts for discoveries that Einstein’s metric formalism cannot cope with, such as concerning those of Mössbauer rotor experiments (Phys. Scr. 2008, 78, 035302). The theory’s predictive and explanatory power, coupled with its falsifiability claims (e.g., rotation-induced CMB signatures, density gradients at cosmological scales, etc.), positions RMD as a viable alternative to the ΛCDM model.
