HD 140283 ("Methuselah"): Age Tension, Boundaries, and Redistribution in ψ₀–OCM

HD 140283 (“Methuselah”) is one of the oldest known stars in the Milky Way, with age estimates that approach — and in some analyses appear to slightly exceed — the age of the Universe inferred under ΛCDM cosmology. This record presents a redistribution-based interpretation within the ψ₀-OCM (Osborne Cosmological Model). Rather than treating time, physical “constants,” and dark energy as fixed background structures, ψ₀-OCM models them as emergent products of a deeper redistribution architecture. In this view, Methuselah does not imply that stars pre-date the Universe. Instead, the apparent tension arises from subtle biases in stellar age inference, redistribution-dependent shifts in early stellar microphysics, and a time-dependent effective expansion history. The result is not a contradiction but a calibration signal. HD 140283 is interpreted as an age calibration node that marks where fixed-background cosmology begins to mis-read redistribution-governed clocks, while remaining consistent with existing astronomical observations. The paper also outlines phenomenological correction terms for stellar chronometry and cosmic age, and discusses observational consequences for other old halo stars and routing-based interpretations of their abundance patterns.
