I cant show you something thats become unresolvable
Thats the problem ppl have
of course. That's not unresolved though, that's half blocked.
If i could show you something thats unresolvable then it would be resolvable not unresolvable
Kevin said it was refraction, but you say it's perspective?
Its angular resolution and gradiant slope
shouldn't the sails be unresolvable too?
Optical slant
and, this is a zoomed image btw
No because they are farther away from you
by like, 2 metres?
2 metres further than the hull
Yes
this is an image from a camera though
might i say ...
"ocean swell" is a real thing, too
..even on lakes, too, but yeah
_Swell waves often have a long wavelength, but this varies due to the size, strength and duration of the weather system responsible for the swell and the size of the water body_
https://en.wikipedia.org/wiki/Swell_(ocean)
Cameras work the same as the eye
@✧Mike Flatbird (Mike Blackbird)✧ Thank you, that is the only other reasonable answer I have got
They just capture more light
?
The focal length is decreased
crap I mean fov
The angles still the same
not focal length
you can see al lthe waves on that water before the ship happens
Once the light is blurred...its blurred
this is how zoom works
you're capturing light from a smaller angle
the focal length is increased, the field of view is decreased
as you look thru too much atmosphere your view will be stopped
you can only zoom in so far
Well how come it only stops the view of the hull and not the sails?
depending on your angle determines how much atmosphere you are looking thru
This is how angular resolution works physically in the eye.

Cameras work the same way.
The cones of the retina is a zoom in of the eye. If the angular size of the target is not enough to activate more than a single cones/sensor the object is unresolvable.
There are 3 ways to decrease angular separation.
1. Move the two separate targets further or closer together.
2.Increase the distance.
3. Change the angle of view.

First here is a demonstration of how angle of view changes the angular separation of 2 targets. https://cdn.discordapp.com/attachments/379214321907007488/459806914331541504/unknown.png
For example in this image, as the stop sign's angular size shrinks from distance or angle, the image that prjected onto the retina also shrinks. Eventually it will reach such as small size the eye can not physically detect the light. https://cdn.discordapp.com/attachments/379214321907007488/459808085436006410/refraction_cornea.png
A geometric analogy would be closing a pair of scissors. When the scissor tips are closer together than the spacing between the rods and cones of the eye then you get to see the target. The point where the tips cross from too close to normal vision is the angular resolution.

When the angle of view becomes to much it pretty much goes parallel, but you lose sight of the ground before that. It's the same on the globe too but even worse because the angle of view is increasing quicker because of the curving away of the ball surface.
These next images show someone how the angle stays the same but the area that you are actually observing increases. You can see the 5th image how the bottom of a building would disappear.

They are using this stuff for self-driving cars. To automate the driving they have to turn the perspective view into an orthographic top down view.

The soure of that image.. http://www.bbc.co.uk/science/0/20937803
Even though the title is BS. No one sees further. You ONLY capture more light.
This is how they build telescopes, to capture light.
Large telescope are reflectors. The larger convex lens gets the more distortion. So they made this. It all works the same generally speaking. A telescope will only help so much. It depends on the light collecting ability that is determined by the diameter of the lens. Some of these aren't built yet...

They are making the lens bigger not building 15 mile long telescopes.
Here is a demonstration of angular resultion effects with an eye charts 1D is distance from chart 2D is 2 time the distance etc...
