The Flat Earth Dome Model — built by a globe defender to show the model fails

The claim

“This interactive dome model shows a working flat Earth with sunrise, seasons, moon phases and eclipses.”

What is true

◆ Refutation The app is real and it does show those things.

What is measured

The model runs on the globe. Its own source code carries an Earth-Sun distance of 149,600,000 km and an Earth-Moon distance of 384,000 km, and its author has published a version where those heliocentric parameters can be edited: change any of them and the predictions break.

What would show this is wrong

a flat-Earth model that computes the positions of Sun, Moon and stars from flat-Earth geometry alone, with no ephemeris input, and predicts the ground track of a future solar eclipse to within a few kilometers.
