  "abstract": "Combined baryon acoustic oscillation and cosmic microwave background data have begun to mildly favor departures from $Λ\\mathrm{CDM}$. This is usually framed as 2-parameter dynamical dark energy. However, a 1-parameter \"cosmic glitch in gravity\" model, whose cosmological gravitational coupling differs from Newton's constant as in Hořava gravity, fits at least as well. $\\textit{Planck}$+ACT+SPT and DESI~DR2 give $G_\\mathrm{cosmo}/G_\\mathrm{N}=0.9920\\pm0.0025$, a $3.3\\,σ$ preference for weaker cosmological gravity, robust to adding CMB lensing and supernovae. Fitted to the CMB alone, the glitch predicts DESI distances; $w_0w_a$CDM does not.",
