Look , these are the same distances. Obviously the angles are not the same. https://cdn.discordapp.com/attachments/379214321907007488/468569265574903818/unknown.png I can make it even more extreme... https://cdn.discordapp.com/attachments/379214321907007488/468569771735253012/unknown.png But guess what....the top of the building will get cut off. When the entire situation is reverse.
Image looking up with your chest up to the world trade center. You wouldn't see the top because the angle would be too shallow. https://cdn.discordapp.com/attachments/379214321907007488/468570710344728576/unknown.png Look what happens when you are closer to the vertical than the horizontal, the reverse. https://cdn.discordapp.com/attachments/379214321907007488/468570964817608715/unknown.png 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? Give that angle , what is the angular separation of the points of light on that target? https://cdn.discordapp.com/attachments/379214321907007488/468574743637786645/unknown.png The relative angle to the plane of the eye and the optical tilt of the target determine the angular separation
If I rotate the green block until it is vertical all the angle will grow. If I rotate it counter clockwise all the angles will shrink. If It was more to scale the angle difference would be more dramatic. https://cdn.discordapp.com/attachments/379214321907007488/468578052302176266/IMG_3195_one_world_trade_center_nyc2015_aagdolla-1038x576.jpg https://cdn.discordapp.com/attachments/379214321907007488/468578348789006336/502382332.jpg Now imagine the building is 3 miles tall and not 1776ft.

Left wall angle is steeper than right wall, relative to the observer. This photo looking upward is a good example also. https://cdn.discordapp.com/attachments/379214321907007488/468579766983720980/OrganicMechanics101.JPG

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.
wait @Citizen Z citizen are u a flat earther or a round?
and btw I said something about fading into the distance
im bringing up a topic lol
Which isn't what is happening
Its just visibility
watch the video
Like viewing a mountain
From far away
Sometimes they look blue
what mountain is blue?
Yes watch the video
If you view a mountain from far away they will start to blend with the sky
and?
Blue light is scattering out the light between you and the mountain
It doesnt
It just proves you cant see infinite
Due to visibility
oh my other point
You were saying they were fading
Im saying thats because of visibility
Nothing more
Me: the thing im confused about is if the earth is flat wouldnt all the water leak off the edge?
you: who told you there is an edge?
me: so ur saying that earth is infinite?
you: who told you the earth had an edge or it is infinite?
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.
Ive never been off north america. I don't know whats out there
okay viewing a mountain from far away it blends with the sky right?
Depends on that days weather conditions, the position of the sun, etc
.
at that time in the video u can still see the mast of the ship, its not blended, it sunk slong the curvature of the earth
So you didn't watch the optics video?
Nothing about blending
Its about optics
Blending is the visibility of the day
Optics im talking about is how light and the eye work
