A logical fallacy commonly committed by the victims of the flat-Earth ideology is CGI related. CGI —or computer graphics imagery— is the use of computers to produce realistic images or videos.
Because this fallacy is very common within the flat-Earth circles, let’s give it the name ‘appeal to CGI’. Its argument has the general form of:
- Observation: a photo or video of an object ‘X’ is made with CGI
- Conclusion: ‘X’ does not exist in the real world
This is a fallacy because it is definitely possible to create a CGI image or video of a real-world object.

If the Earth is round, and it pulls water to its surface; why a ball does not pull water, even though both are round?
Because gravity is not caused by the shape of an object. Gravity is caused by mass. Everything with mass have gravity. The larger the mass of an object, the greater its force of gravity.
The ball has much smaller mass than the Earth, it is not even close. Correspondingly, its gravity is also much smaller.
Besides, the experiment is obviously done in Earth environment. The Earth —that has much larger mass than the container of the water— has much bigger influence on the shape of the water surface, than the container itself.
The surface of the water will form a spherical shape, with the same center as the center of the Earth. As the center of the Earth is too far away, the curvature is not perceptible. According to our calculation, in a container 10 cm wide, the bulge of the curvature is only about 0.0000002 mm.
It is a very small bulge, and impossible to perceive. Other forces —like adhesion and cohesion— will have greater influence on water in such small container.
“Why don’t we see satellites in photos taken from the ISS?” (or from space in general). That’s a recurring question within the flat-Earth community, usually asked without expecting an answer, assuming that an answer is impossible, and that it is a glaring oversight when the powers that be purposefully made the picture using CGI.
But no, the pictures are real. And satellites are not visible because they are too far spaced apart from each other.

Many flat-Earthers will tell you that Nikola Tesla is actually a flat-Earther. The supposed ‘evidence’ is a piece of quote that is claimed to be from Tesla himself; but in fact, it is not. It is actually a really terrible misquote, and an attempt to take the quote out of context.
The source of this problem is apparently a Facebook post that quotes Tesla, as well as a Facebook user named ‘Darrell Fox’.

Accounting for the curvature of the Earth is not usually needed for narrow high-rise building projects. Designers only need to ensure the foundation is flat, and the curvature of the Earth becomes non-factor.
For projects that extend over a long distance, like roads, railroads, canals, etc, they are built along the curvature of the Earth, and specifically accounting for the curvature is usually not needed.
But when the project extends on a long a distance, as well as extending upwards, then we have no choice but to take the curvature of the Earth into account. One of such projects is the Verrazano-Narrows Bridge, New York, United States.

‘The Principle’ is a pseudoscientific documentary that promotes geocentrism, that the Earth is stationary and the center of the universe. Despite the fact that the film has almost nothing to do with flat-Earth, some flat-Earthers decide to use this film to bolster their beliefs. Because after all, in the flat-Earth model, the Earth is stationary and the center of the universe, right?
This actually gets more complicated than that. We are dealing with two forms of pseudoscience, that sometimes even goes against each other.

Little Piggy is the nickname of a helium balloon launched by IndianaCaver. It reached the altitude of almost 37 km, before it finally ruptured and fell to the Earth. Before that, it took several hours of video, and IndianaCaver made these video available on YouTube.
Then, some flat-Earthers cherry picked bits of video where the horizon looks flat and presented it as ‘proof’ of flat-Earth. These are widely circulated in various memes and forms, even years after the originals were published.
But, can we really use these videos as ‘proof’ of flat-Earth?

The Nikon Coolpix P900 camera is a very popular camera among flat-Earthers because there’s no other compact camera ever made that has such enormous zoom range. It is a unique and a very useful tool in this state of affair.
Someday, some flat-Earthers decided to bring their trusty P900s out and used them to take some pictures of Venus. To their delight, the resulting pictures don’t look like Venus we all used to know. They were too excited that they thought they have discovered an original ‘proof’ of global deception. “This is an irrefutable ‘proof’ that they have been lying to us!” so they say.
But, maybe there’s a simpler, more plausible explanation…

Some flat-Earthers use the so called global conspiracy as an ‘escape hatch’ in order to abandon a losing argument without having to appear to lose face.
When unable to defend the flat-Earth hypothesis, some flat-Earthers will tell you the ‘flat-Earth theory’ is a work in progress, it is normal for it to be incomplete, for now. “But, ” it is inevitable they would say this, “the most important thing is to uncover the global conspiracy and save the world from these unscrupulous few!”
But, the global conspiracy theory itself is simply an invention.

Every time we see a rocket launch, its trajectory is always curved, never straight up. Why would they do that? Aren’t they supposed to go up to space?
No, it is not because they have malicious intentions, as implied by a lot of flat-Earthers.
The curved trajectory is what we call the ‘gravity turn’.
