>Vauxhall; Does FET take into account curvature like hills, mountains, etc.? In the city where I live I often feel the roundness of the ground as i walk across certain areas. I could see a Zetetic counter argument from people who live in very mountainous areas for example. If mathematics, video, photography, etc., aren't enough to satisfy ZP, then what sort of experimentation would be enough to satisfy an observation?
It seems like a massive experiment would have to take place to prove without any doubt that FET is true. And it could be the case that to satisfy ZP, the world technology would have to advance a great deal because it would have to be tangible evidence and not documented evidence. ZP is difficult to persuade, so I wonder if that might be the "essence" of it. A sort of stubbornness that requires 100% tangible evidence to be satisfied.
