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.
Next eratosthenes
Ok
Disprove that
Also. They didn't even have clocks back then. They couldn't have known when it was exactly noon in Alexandria if they were in syene
When the sun is exactly above one stick they couldn't have know when that was 400 miles away. They had no clock. No phone. No radio.
The story is nothing more than a myth
Plus it works for a flat earth or a globe earth
Just make assumptions first.
All were wrong
It works for both.
I just showed you
Stop denying
Hypothesis 1
Hypothesis 2
Same.
What abt the fact that with a telescope you can see other planets that are spheres
Or the fact that satalites orbit the earth
And the fact that it's night on one half of the earth and day on the other side
balloons with relay antennae
ha ha
balloon satellite constellation relay network
If the earth is shaped like that
Then explain a lunar eclipse
The earth projects it's shadow of a round earth
