Science is used to help Describe, Explain, Predict, and Control any phenomena studied. The Describe and Explain part would be the pure science, and the Predict and Control parts are the applied science part.
Instead of letting a Flat Earther moo on and on about the Describe and Explain part, force them to show devices, procedures or processes that have been created out of Flat Earther Descriptions and Explanations of reality.
If their observations are accurate, they should be able to demonstrate or generate something useful from their special knowledge. It should be something that simply cannot be generated using conventional Round Earth Descriptions or Explanations.
Tl;dr: Flat Earthers are unable to demonstrate practical application of their special knowledge that improves any process.
If they don’t produce, the discussion is over.










I’m more interested in the put up or shut up, and less interested in the alleged internal struggle that prevents them from doing so.
Produce.
