All explained by FET.
Oh, isn't that great? How marvellous!
Please Jora, would you summarise how FET explains these things from the list above:
1. Navigation, specifically how inertial navigation systems work on a flat earth.
2. Neutrinos, specifically observations of solar neutrinos which appear to have passed through the earth.
3. Surveying, specifically why the horizon viewed through a theodolite is below horizontal level from any appreciable altitude.
4. Maps, specifically why it appears to be impossible to produce a functional FE map but very easy to produce a functional RE map.
I'll get the popcorn and we can watch him fail to answer these.
Oh BTW Jora, I'm rather puzzled why you think the horizon isn't visual evidence of curvature? It's exactly what you'd expect to see on a big ball.
