This research aims to test the dark energy predictions of the Order Parameter Spacetime Theory using baryon acoustic oscillations and growth rate measurements.
Analyzed DESI DR2 baryon acoustic oscillation distance measurements and DESI DR1 growth rate measurements.
Fitted data at 7 effective redshifts (z = 0.295–2.33) and 5 redshifts (z = 0.15–1.48), totaling 12 independent data points.
Expanded the prior range of the feedback coefficient c₀ for model fitting.
Best-fit value for the feedback coefficient is c₀ = 0.0 and α = 0.866.
Identical χ² = 19.28 and best-fit cosmological parameters (H₀ = 68.93 km/s/Mpc, Ω_m = 0.299) for both the Order Parameter Spacetime Theory and ΛCDM.
Information criteria mildly favor ΛCDM over the Order Parameter Spacetime Theory, but no significant distinction is found.
