I think it was either a Miniminuteman or a Folding Ideas video that showed what some flatties proposed: the Sun moves in a wacky repeating spiral pattern above the surface. It’s closer to the Arctic during summer and to the Antarctic during winter, which they claim to explain the different angles of incidence. Obviously that doesn’t conform to any physical laws… observed phenomena… ideas that a person of ordinary intelligence might come up with… their own models of flat Earth… but flatties are nothing if not persistent in their dogmatic rejection of reality.
