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

In conjunction

Imagine extending that 60 miles

The angle will become so shallow that the eye or lens will lose its ability to resolve objects in the cone

is this entire thing about earth being flat

yeah

ok

im a round earther

same

this guy thinks that you cant perceive things as round if you are far away

it litterally shows the object dipping below the horizon in the gif

No

yes

It shows angular resolution

What does this mean?

its dipping below the horizon because when you look at it from far away it dips along the curvature of the earth

Says who?

says everybody except flat earthers

Its not dipping below any curve

yes it is

Ive just shown you

How light works

Your problem if you refuse to learn

We will have to agree to disagree

okay new topic how do tides work
