As in some FE contend that the horizon line would and always rises to eye-level
Have you considered bringing it up with the people who hold this view? You're unlikely to find them here, and repeatedly trying to bait people into this by saying "well, sOmE FE'ers claim this" only encourages people not to take you seriously.
SoMe Re'ErS can't even figure out the difference between velocity and acceleration. SoMe Re'ErS think that spirit levels can only operate thanks to the nigh-immeasurable differences in gravity affecting 2 ends of the tube. And that's just with things sOmE rE'eRs claim today - if we started digging up centuries-old beliefs, there's more fun to be had. We don't hold all of RE accountable to that, because that would be an utterly psychotic thing to do.
If you want an argument from your anonymous "some FE'ers", go talk to them.
A couple of things…
I was being cautious by using “some”. As in the past if I were to simply say, “FErs claim that blah, blah, blah…” I would get blasted by you for implying
all FErs. So now, if I say “some”, that still seems to be an issue.
For two, there’s some stuff in the wiki regarding horizon/eye-level/dip experiments and observations that are stated as inaccurate. It appears to me as a refutation of GE’s claim of dip due to curvature considering that’s exactly what the experiments are designed to show:
Water Level DevicesThere’s also this in the wiki leading me to believe that some FEr's may dispute the dip:
“
...since it is the nature of level surfaces to appear to rise to a level with the eye of the observer. This is ocular demonstration and proof that Earth is not a globe.”
And
“
...no matter how high we ascend above the level of the sea, the horizon rises on and still on as we rise, so that it is always on a level with the eye…"
Also, there was a request back in 2018 to remove this from the wiki:
”A fact of basic perspective is that the line of the horizon is always at eye level with the observer. This will help us understand how viewing distance works, in addition to the sinking ship effect.
Have you ever noticed that as you climb a mountain the line of the horizon seems to rise with you? This is because the vanishing point is always at eye level with the observer. This is a very basic property of perspective. From a plane or a mountain, however high you ascend - the horizon will rise to your eye level. The next time you climb in altitude study the horizon closely and observe as it rises with your eye level. The horizon will continue to rise with altitude, at eye level with the observer, until there is no more land to see."
Since I can’t seem to find it in the wiki, I guess it was removed. Perhaps it was removed when a new redirect was created in 2019:
• Horizon always at Eye Level
#REDIRECT [[High Altitude Horizon Dip]]

All that said, if some or all FEr’s here are no longer in the horizon always at eye-level camp anymore then, I guess, never mind.
