Per mile squared
Get it right
your going to continue to use stuff I said out of context?
YES
don't quote me again Big Lover
It's kinda funny
I'm warning you
No
The context matters
You’re getting the math entirely wrong Kevin. It’s 8 inches per mile squared. A tiny mistake in wording, but it makes a huge difference.
So one mile is eight inches
he's not interested in facts
Its the principle that matters meta
but good point nonetheless
Approximately
Yes why does the horizon occur anyway?
the problem is that if you actually try to use it for close work, you can have hills creating fake curvature
or you can have someone level the hills, and then what, you removed that curvature in the short term?
some places are flatter than other places
Kevin did u see metaphysical recent change
Goto reception
Kevin why does the horizon exist, and why does it get more distant as you gain altitude?
Lol
@The18thDoctor gradiant slope
Optical slant
Do you have some sort of diagram?
Sure

What object or thing blocks the light from things beyond the horizon?
this shows perspective, and convergence at your viewing distance

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.
Gimme professor role
Big Lover keeps quoting me out of context Citizen Z, don't make him a professor
