Flat Earth General / Re: Why don’t FE’rs get together to do this experiment to measure earth’s curvature?

I’ve sailed around the world jackass. It’s a globe.
Special in that I’ve sailed west and never ended up at an ice wall. Always stayed in the tropics.
You literally don't understand my explanations, hence pictures where you talk about how the sun is still in line of sight.
I repeatedly explain what this parabola does,
We get it, apply it, and find it doesn’t predict what is actually witnessed in real life, is useless, and that you have to contradict yourself..
Like the simple fact I witnessed lobster boats going out to sea down a river and had to fight the tide coming in to get out of the river to the sea.
Or…
Third, you've never learned was east and west are on a FE map
Because it doesn’t work on flat earth for what is actually east and west and how those directions are relative to actual land masses.
The pink arrow on the map off the US East coast should point east to where the sun rises on the equinox. The relative direction of the pink arrow should point to the coast of Portugal/Spain. Going the general direction of the pink arrow doesn’t take you to south. If the earth was flat, traveling any direction would eventually take you to the supposed ice wall. Traveling due east or due west for much of the world does not lead to the Arctic or to the Antarctic. FE fails at relative direction of land masses to each other as they are known.
Where the sun on a flat earth would have to rise north / south for large areas of the world where in the equinox the sun rises due east and sets due west.
Thing is, like most woke globalists,
Which has nothing to do with…
The sun does shrink, but not always, as you yourself probably "proved" with your Seeing No Shrinkage This Week thread.
If you think the above, then you need too…
Bulma. Say a live in Norther Ohio.
Draw an overhead flat earth map showing the relative location of Ohio and draw the path of the sun over that flat earth map for march 20th 2025.
Bulma, writing checks they can’t cash.
From another thread, but drives home the earth is a globe.
Surveyors know Earths surface is flat, know there’s no curvature on Earths surface.
Actually large survey projects prove the earth is spherical.
Anyway..

US road grid corrections because of the Earth’s curvature
Have you ever wondered why, when you’re driving along on a straight road in the Western US, there’s a weird curve or short zigzag turn thrown into the mix? Grids have been used to lay out American roads and houses since before there was a United States. One of the most prominent uses of the grid was in the Western US: the so-called Jefferson Grid.
The Land Ordinance of 1785, drafted by Thomas Jefferson, extended government authority over the Mississippi River and the Great Lakes regions. As a response to what he believed to be a confusing survey system already in use, Jefferson suggested a new grid system based on the rectangle. The grid divided land into plots one mile square, each consisting of 640 acres. The grid also placed a visible design upon a relatively untouched landscape.
As most people know, the Earth is roughly spherical. When you try to cover the surface of a sphere with squares, they are not going to line up perfectly. That means, every so often, sections of the grid shift away from each other. Gerco de Ruijter’s short film, Grid Corrections, shows dozens of examples of places where this shift occurs and the corrections employed to correct them.
By superimposing a rectangular grid on the earth surface, a grid built from exact square miles, the spherical deviations have to be fixed. After all, the grid has only two dimensions. The north-south boundaries in the grid are on the lines of longitude, which converge to the north. The roads that follow these boundaries must dogleg every twenty-four miles to counter the diminishing distances.

The reason for so many map projections is due to the fact the earth is spherical.

Why all world maps are wrong
If the earth was flat, there wouldn’t be a need for all the crazy map projections trying to correct one aspect while exaggerating other aspects.
