The Ship Under the Curve Explanation Debunked

Debunking Round Earth "Evidence": A ship does not disappear over the horizon

One of the most frequent pieces of evidence I get from round earthers is that since a ship disappears over the horizon the earth must be curved. This is wrong. The reason a ship looks smaller and smaller until it disappears is simply just a matter of perspective. The further a ship goes away from the observer the smaller it appears eventually the the viewer cannot determine ship from sea and there fore the viewer wrongly concludes that the ship "sailed over the horizon"



You can see that in the diagram above the further away a ship goes the smaller it appears. Eventually line w will intersect line E and the viewer will perceive the ship as disappearing. All round earthers have to do to test this theory is watch ships leaving a harbor. Eventually the round earthers will see that the ships get smaller and smaller until they cannot see the ship anymore. Round earthers feel free to debate me in the comments I look forward to debunking them.

  1. If you think that "round earthers" don't understand how perspective works, then you are more out of your league that previously thought. See, there is a perspective phenomena known as parallax and it has some incredible applications in science.

    Parallax is the effect whereby the position or direction of an object appears to differ when viewed from different positions, e.g., through the viewfinder and the lens of a camera.

    Using trigonometry we can deduce the distance to heavenly bodies merely based on angles and standard luminosities. Early astronomers used parallax to estimate the distance to the sun, even other planets.

    To say that the ship just gets smaller and smaller is just plain wrong. If you had a powerful enough telescope you could see the ship hundreds and hundreds of miles away. Take a satellite for example. When one passes in front of the moon, you can see it with a telescope. The ship, however, will disappear, EVEN WITH A POWERFUL TELESCOPE. But try this, once you can no longer see the ship with the telescope (the second it disappears from view) get in a hot air baloon/skyscraper/whatever and increase your elevation. If you go high enough and peer through the scope, voila! The ship appears again, because you adjusted your angle and can see over the curve. Look how smart you are! you did it! you just solved a basic freshman geography problem!

    1. just an edit. "you could see the ship hundreds and hundreds of miles away - if you were on a flat plane"

    2. The ship disappearing could be explained by water refracting light in such a way to create an illusion, similar to mirages

    3. Did you even read what I said? I said if you go up in a balloon you can see it but when you are on the surface, you cant. That is because there is curvature, not light interference from the water. The mirage argument is so overplayed.

  2. Your diagram makes at least one huge error, and probably several. When you draw a scale diagram and measure the angular width of a distant object as seen by the eye you find that to halve the apparent size you have to double the distance. One quarter the size, four times the distance, one tenth, ten times the distance and so on. So the smaller and smaller ships should be spaced further and further apart. The line you draw connecting the mast's lines should not be straight but curved. Likewise the line connecting the ships hulls. These lines never meet. You have not described what the other lines represent. If they represent points on the ship those lines also will never meet when drawn correctly.

    I suspect the drawing is confusing two different diagrams, but how it was constructed is not my problem. It is wrong.

    There is a second confusion. If you watch a ship go off into the distance you will see the width and also the length decreasing in the same proportion as the height. The decrease in apparent width does not cause one side or the other of the ship to disappear. But the geometric properties of perspective are symmetrical about the line between observer and object. There is no reason for them to be different horizontally or vertically. Yet no flat earther ever suggests a ship disappears over the horizon from the side, because no ship ever does.

    Finally the scale from front to back changes with distance in the same proportion as height and width. This is the classic compression of perspective. As a result you have to go infinitely far to make the ship appear infinitely small, and the vanishing point can never be reached. But that would also be apparent if you drew the sides or top and bottom of the ship on a scale diagram when working out the angles. At every distance the actual size of the ship is the same, so the lines connecting the extremes of the ship drawn at different distances (L,R Top ,Bottom) are parallel, and parallel lines never meet. The apparent size of the ship is the angle subtended at the observer's eye, which is set by the width or height and the distance using the normal laws of geometry or trigonometry.

  3. Thanks for the great post on your blog, it really gives me an insight on this topic.
