Its not a curve

You haven't proved light yet

Its the angle

Ffs gnite

Gnite babe

Look at your phone

You can see everything

Now tilt your phone away from you till its completely horizontal

That's not light it just changes color

Notice how you cant see much of it

The more shallow the angle the less you can see

Increasing the angle and distance is what makes things disappear from bottom up

The more distant, the more shallow the angle

Wouldn't a shallow angle cause the whole thing to obscure evenly though

No

See the drawing

See the vertical lines i marked in yellow?

No because my phone's still tilted

Now see the observer i marked in red on left

The red observer is closer to bottom than top

So how would this cause an object to disappear from view? The observer is always above the object on a flat plane.

See green line is shorter than purple line

Imagine the lines marked in yellow are buildings

Buildings don't move

The red observer is closer to the bottom than top

Ur not following

Sorry I'll stop

Ok go on

See how the camera is closer to left side of hallway

Yeah

The pillars start to blend together faster on the side the observer is closest to

Ok

You can see more of the pillars on the ones further away

Thats because the angular resolution

You're able to distinguish them anyway

Another example

The pillars are still there, it's just hard to tell one from another

Closer to left

It doesn't make the hallway appear to be curving

You lose the objects you are closer to first

The ocean doesnt curve either

There is a difference between losing an object and not being able to distinguish it from other objects

You are just losing what's closest to you first

The human eye has angular resolution limit of .02 degrees

Once the light hits the retina at .02 degrees resolution the object is no longer reasolvable

You dont lose the entire object all at once

Just the part that reached the resolution limit

As it gets further away, the angle will continue to become more shallow

Ah ok now I see

Until it all disappears

So for example if there was something sticking out from between two of the farther pillars you would see it

It appears like there is a curve

Yes you would see things sticking out

Ok I'm following

Its called gradiant slope or optical slant

Imagine looking at a painting on the wall

Then go up to the wall and look down the wall

You would only see the frame

The angle is gone

So as an expansion of that, say the hallway went as far as the eye could see, until the left pillars melded with the right

And there were mini sails sticking out from between the pillars on the left

At the same distance

Right so if you put a boat going down the hallway...you would lose the portion you are closest to first

It would need to be a very long hallway

Miles and miles

Hmm ok

How does the sail disappear so fast then

Wouldn't it have to travel much further to disappear?

The sail disapears last cuz its further away from you

Ok

Imagine the sail isnt a sail

Its billions and trillions of points of light

Trillions of photons coming to your eye

Those photons are on a steeper angle than the hull compared to your position on the beach

The sail is higher up

Steeper angle

Will be resolvable longer

See how the light blends together on right side of hallway faster than left side

Cuz the camera is closer to right side

The angle is more shallow

But the hallway doesnt curve

We know that

Yet we lose the door frames and picture frames

Oh lord

See the building you are closer to becomes less reasolvable than the building further away

Satan never could understand optics

🤗

I'm gonna have to continue this in a bit I gotta get back to work

In the meantime what's the distance that is required for a ship to fully disappear relative to its height

5 ft at about 15000 feet

Which means you lose objects at 5ft tall at about 3 miles
