The muon g-2 measurements have nothing to do with floating rocks. This is not a superconductor update.
This is a high energy physics thing about failing to find something beyond the standard model. Just your regularly scheduled "5 sigma physics anomalies that disappear on their own with better measurements" programming.
Right. I mean that measurements conflicted with theory, and the new CMD-3 measurements suggest a better calculation. Assuming CMD-3 is good, there's no significant gap between theory results and collider results
That wasn't the only change. There was an alternate computational scheme that didn't depend on electron-positron experiments that gave results consistent with the Muon g-2 experiment.
