Waton- actually that's the kind of misinformation I was referring to. Even if well intentioned, it's wrong. Given sufficient distance on a flat plane, you have the same effect with the horizon. In fact, almost all math works the same when you are just one observer on/near the surface (near meaning not in space)
I'm not a flat earth proponent, as I have mentioned, but bad science doesn't help anyone.
The question is though, who cares? Rounders think Flatters are stupid, Flatters thing Rounders are deceived, but aside from ego issues, who really cares? We navigate by flat earth models on land, sea and air, we build according to flat earth models, and so much more but really if you are not doing that, and the model you use for what you're doing works, what's the difference?
The world could use a little less US vs THEM.
