Dark energy and OQG in Practice
What if our cosmic measuring standards have a history?
Clocks, rulers, free fall, and cosmic expansion are treated as physical comparisons made with matter. A history of changing material standards is fitted to cosmic chronometers and tested against six DESI DR2 measurements without refitting, on a branch with no physical dark-energy density.

Cosmology without dark energy
A two-parameter model fitted to 32 cosmic chronometer measurements reproduces all six DESI DR2 Alcock–Paczyński measurements without refitting, with χ² = 6.60 and every marginal residual below 1.6σ. This provides a quantitative cosmological application of OQG without a physical dark-energy density.
