The second 2 are to show how the points of light will merge into onehttps://cdn.discordapp.com/attachments/379214321907007488/468601108441595906/unknown.png These are two points of light that are close. https://cdn.discordapp.com/attachments/379214321907007488/468601846089646090/unknown.png

How angular resolution works:

The further an object (i.e. boat, building mountain) gets away from the lens, the angular separation will continue to close until the light blurs together and eventually becomes a line or point or edge"

"As he looks downward toward his feet the slant approaches zero, as he looks upward the slant increases, as the center of clear vision approaches the horizon the slant becomes maximal, and at the horizon itself the land ceases to be a surface and becomes an edge"

As you look down the right side of the hallway, you'll see the angular separation of light begins to close the further you look. Then looking at the left side of the hallway you'll notice the angular separation of light does not close or blur as quickly as the right side.

Here are some questions you can ask yourself. Where is the plane of the eye? What is the relative angle between the surface of target and the plane of the eye? Given that angle , what is the angular separation of the points of light on that target?

Notice the blue cones angle compared to the orange cone. The blue cones angle will lose the light first on the bottom and the ground will start to blur with the object but if you raise in height the resolution will increase shown with the orange cone because the angle of light hitting the retina or camera is made larger. Once the angle becomes too shallow the light turns into a line or Edge. Think of buildings or boats or mountains not as objects but as quadrillions of points of light or photons coming to your retina at different angles and some will become non-resolvable before others. The ones closest to you disappear first as you back away. You will see the ground running up to the horizon then see the horizon as a line and will see things like the sky still or if there's a mountain or building you will still see the top parts but eventually those will also become unresolvable as they get further away and the angle changes.

optics arent gonna prove anything they think u can see 300 light years away so nothing optical will every prove it to them they cherry pick what is real at the horizon or what is an optical illusion so
@GandalfTheGreen you should watch that. Maybe bring you back to the reality of how perspective works
@Citizen Z Once you understand that if you want to prove something is flat and level, you need to be parrellel to it. I know exactly how perspectie works, and why flat earthers need lines to baby step them through it. The reality of the situation, is that your vision has been manipulated for a very long time.
Okay whats the concave curve math
Let me know when you're done reading that.
"A Ground level camera removes zonular accomadation caused by objects being beneath eye level allowing you to measure a level objects relationship to the things potentially above it."
Think of your eyes, as like... Concial regions of sight.
If you are looking down that is.
IF you are flat with something, looking dead on, it removes that perspective .
Light flashlights, how they project a conical beam
You receive ligth in this fashion.
If you lay flat and even with a surface, you can tell if it's flat and even, because the region of perspective changes to match the actual enviroment.
You will always see a "flat earth" at eye level.
You're only going to be able to tell it's not flat by lying down and using a high powered lense to demonstrate the horizon higher than the things above the "flat" water.
Why does the sky meet the ground
Is the sky convex then?
You arent thinking of basic perspective
lol.
Its simpe stuff
No, it's rather complex
And you would rather not sit through it all.
But the math works
That's cute stuff bibleman.
