Perspective is why boats disappear from the bottom up. Ever heard of the angular resolution limits of your eyes?
Every single photo from high altitudes with a normal lens camera shows a flat level horizon at eye level. Have you heard of the black swan? It also destroys the curvature.
Where do you get your straight line for the use of the sextant? The sextant is an angle measuring device and you don't have a flat baseline when measuring on a ball.
If you seriously think you have proof of a globe you should take this guy's 3 bitcoin challenge.
You must think flat earthers actually think what the flat earth society thinks. Not one actual flat earther thinks that. Even they find it retarded. The flat earth society is a legit psyop designed to discredit flat earth and make it look retarded. Flat earthers can't give you all the answers you want because they don't gain grants and funding for research like globetards do.
It's not perspective; you completely misunderstand it. It's the fact that the last part to be seen is the highest. So also with skyscrapers. I am quite familiar with the angular limits of one's eyes, as I worked for 2 years on quality control optical instrumentation for the production of intraocular lenses. Are you so familiar? You don't make any point of it.
I never alluded to horizon curvature as meaning anything. It doesn't (both a flat or spherical earth will have a curved horizon). The shape of the horizon as photographed has more to do with whatever optical distortion is caused by the lens. (Panoramic lenses are prone to barrel or "fish-eye" distortion.) Or what angular sector of view is being photographed. Once again, a small enough angle will make it look flat.
The sextant takes the angular measure of the heavenly object that is the target relative to the visible horizon. No problem. Doing it for over a century.
Bitcoins are worthless, in my opinion. I don't have anything to prove that decades of orbital flight hasn't already proven.
I don't care what the Flat EarthSociety thinks. I am trying to get you (a flat earther) to reveal what you think. So far, it is confused junk and ignorance. I have not been seeking "answers" to any questions. I have been requesting the key argument proving the Earth is flat, and you don't seem to have the faintest idea of what it could be. All you can do is question well-known phenomena from the standpoint of someone who doesn't know squat about the phenomena. Real brainy.
The fact that you have zero proof of curvature I would say proves we live on a relatively flat topographical plane. The fact that I can see entirely way too far. The fact that boats in your southern hemisphere still have to correct to the north when traveling east and west. How about the fact that when military shoots artillery they assume a flat non rotating plane when calculating their shots because lives are on the line and if they relied on ball math people would die.
You are mistaken. I never said there was a lack of proof of curvature. First, we can see the Earth as a sphere from space. Second, we can induce the fact of spherical curvature from the fact that surface geometry satisfies spherical trigonometry (the angles of a triangle add to greater than 180 degrees). Any given locality seems flat, but that extends only for about 100 km, and then we begin to notice it is not flat. Can you see entirely too far? How far is that, and why is it too far? (Perhaps you are omitting the refraction of light at low angles.) I don't know what you mean by "boats in the southern hemisphere... correct to the north." What has that to do with curve or flatness? Military artillery can use a flat earth APPROXIMATION if the distances are short, but when the distances are large, they have to use orbital mechanics (e.g., ballistic missiles).
The "curvature killers" are pathetic. It is quite impossible to understand what they are trying to say. Drawing any conclusions from Earth topography is crucially dependent on whether the topography is, in itself, spherical in contour. (Or do you deny the existence of topography and insist the Earth really is absolutely flat?)
So much for your usual list of things about the Earth you don't understand. Where is the key fact that proves it is flat? Where is the self-consistent flat map? Where are the photos of the edge? How is it possible to travel along the equator (a straight line) and circumnavigate the Earth?
I'm sorry but your earth model necessitates a geometric horizon of no more than 1.22 times the square root of the observers height in feet. That is plenty accurate enough for local measurements. Guess what, horizon isn't geometric. It's an apparent location. Your model requires a geometric horizon.

Here is a playlist of quite a few curvature killers. https://youtube.com/playlist?list=PLEzivhxtxgbsRfA1jEZsHFDJ3JJNeQkkB

Still haven't given me evidence. You' might be the most retarded globe yet.
