Is DESI Seeing Dynamical Dark Energy, or a Cosmic Glitch in Gravity?
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 differ
