We've been discussing the recent rise in people who believe the earth is flat, and how one of the methods they employ to bring the gullible into their cult is telling half-truths that are just believable enough to fool people who don't have the time or ability to check the claims.

One of these half-truths that we touched on just a bit in our article Everything You Wanted to Know About the Horizon, is the difference between objects that are far away disappearing due to being beyond their vanishing point versus objects that disappear over the horizon.
One of the flat earth deception techniques is to conflate these two concepts with objects that are just the right size to disappear due to vanishing point immediately before or right on the horizon, and to then use a telescope or high-powered zoom lens, declaring that anyone can bring back any object beyond the horizon so long as a sufficiently powerful telescope is used.
The vanishing point of an object is when the object is so far away from you it seems to disappear. Objects will disappear at different distances from you depending upon their size, your vision, and potentially atmospheric conditions. But the smaller the object, the closer to you it will reach it's vanishing point, and the contrary is true as well; the larger an object, the further away from you it will seem to vanish.

In order to promote their deception, flat earthers will use videos like this one below that show a buoy on the ocean that is past its vanishing point, but not past the horizon. When they zoom in on it, they claim that it was, indeed, past the horizon, then claim that you can zoom in on any object past the horizon. But it was merely past it's vanishing point and not over the horizon.
This is an image of the buoy in the video above. Note that you can still see water behind the buoy. It is clearly in front of the horizon and not over or even on the horizon. But flat earthers are using this as an example of an object having disappeared over the horizon and having been brought back with a zoom lens, when it's nothing but a deceptive trick, or possibly ignorance.

For many people, videos like the first one are shocking because they do not understand the difference between vanishing point and the horizon, and really believe that the buoy was beyond the horizon! Along with a lot of psychological techniques telling them they are being lied to by, basically, the entire world, and assuring them they are 'awoken' to the truth and are so smart that they can't be fooled by a global conspiracy, many people are deceived into thinking the earth truly is flat by this video and others like it.
Versus Over the Horizon
But these videos merely show objects past their vanishing point because the object is small. When you get a large object, such as the container ship in the video below, you'll see that part or all of the ship is obscured by the horizon before it reaches it's vanishing point. The portion obscured by the horizon, it can be easily seen, cannot be zoomed back in with the zoom lens, and the rest of the boat is obviously visible, so it is clearly not an issue of the bottom being too small to see. It's simply obscured by the curvature of the earth!
Because those susceptible to these psychological techniques feel special and incredibly intelligent for having uncovered the largest and longest conspiracy in the world and outsmarting every scientist who has ever lived, many simply never look for any evidence contradicting this deception before rejecting over 2000 years of scientific inquiry on the shape of the earth!
One of the favorite comments flat earthers make is that mainstream science is wrong and that every flat earther is a 'real' scientist. Yet, unlike actual scientists, providing evidence contrary to their fantasy doesn't mean they give up feeling like one of the smartest people to have ever lived. Instead, they will invent something to explain away the reality or a spheroidal earth that you must accept unconditionally else be labeled a brainwashed shill or part of a worldwide conspiracy to hide the true shape of the earth.
In this case, many have realized that these objects simply cannot be brought back with a telescope, so they now claim that objects disappearing by 'perspective' just disappear bottom first, when it's clear to anyone who has watched small objects disappear into the distance, like these batteries on colored paper prove, this is simply not true. We can still see the furthest away colored paper on the floor, just as we'd expect to see.

It's quite amazing that this phenomenon has popped up when it's so easy to find out the shape of the earth through simple methods like I outline in the article Horizon Drop: the Easiest Way to Prove the Curvature of the Earth. Unfortunately, this is the reality of this growing minority that seems to be incredibly appealing to many.
Seeing the deception being done will hopefully dissuade at least a few of those less susceptible to these psychological tactics. I'm afraid, however, that most who identify as flat earthers are too far gone to have their beliefs changed with facts and reason.
