If you record the exact moment a star disappears behind a mountain peak, the globe and flat "models" have different time predictions.
Using a null hypothesis (globe) vs alternative (flat), you test which model has the more accurate predictions. Across 32 observations over 14 different peaks, the difference between predicted and observed occlusion timing consistently favoured the flat model. On a globe you would expect residuals randomly distributed around zero. Instead they are consistently offset in the direction of the flat prediction.
The great thing about this experiment is all the data is there "open source" for anyone to refute.
