From an airplane or a mountain, however high you ascend, the horizon will always appear to rise to your eye level. But if you measure it, you will see that the horizon is actually somewhat below your eye level - about 3 degrees below, for example, from an airplane at 35,000 feet."
Could you clarify the meaning of ‘below’ here? I assume it means that the angle between a line from the horizon to the eye, and a line pointing ‘downwards’, is less than 90 degrees?
Also a definition of ‘downwards’ in the wiki would help. We can’t say ‘direction of gravity’ because FE denies gravity. Or does it? How about ‘the direction in which things fall’ or something like that.
[edit] I just noticed 'perpendicular to plumb', which is good definition assuming you understand 'perpendicular' and 'plumb'.
This is an interesting suggestion, but I can't help but notice the intentional introduction of bias. Perhaps if you propose a more neutral change, I'll consider it seriously? As it stands, you're asking me to include RE hand-waving in a FE wiki. I might be an idiot, but I'm not *that* incompetent.
How about: "From an airplane or a mountain, however high you ascend, the horizon will always appear to rise to your eye level. Proponents of the globe earth claim that the horizon is
actually somewhat below your eye level, supposedly about 3 degrees from an airplane at 35,000 feet, however this is false".
