Humans Are Social Beings and Science is a Social Process

Humans are social beings. We depend on each other; not everything we need to do can be done by ourselves. We do not produce every food we eat every day, and the same applies to practically every other aspects of our lives.

We often hear flat-Earthers ask if we have researched by ourselves all the things we claim. If we have not researched it by ourselves but only rely on information from third-party, then —according to them— we should not accept the information. It is merely their way to undermine society, and disconnect us from the rest of society.

Balloon Satellites

In the context of spaceflight, a satellite is an object that has been intentionally placed into orbit. A few of these satellites are balloon satellites. They are satellites that are inflated with gas after they have been put into orbit. There are also other human-made objects which are also called satellites, only placed in a much lower altitude, and with a very different operating method. These include the geostationary balloon satellites and atmospheric satellites.

Flat-Earthers deny the existence of satellites, and after they discovered the existence of balloon satellites, they started to use the fact as “proof” that orbiting satellites do not exist. It is the fallacy of hasty generalization. Using the same “logic” they are using, we can use the existence of trucks to “prove” buses don’t exist.

Shill Gambit

The shill gambit is a fallacy where one party dismisses another party’s arguments by proclaiming them to be on the payroll of some conspiracy, without having any evidence other than the arguments themselves. The shill gambit is a type of ad hominem and poisoning-the-well fallacy. It shifts from addressing the substance of the argument to attacking the person and their credibility instead.

Flat-Earthers would usually commit the shill gambit when they feel cornered. They would accuse anyone outspoken against flat Earth to have been paid by the global conspiracy. We at FlatEarth.ws get these accusations a lot.

Notable Effort Fallacy

The fallacy of notable effort is committed if one accepts good effort as a valid reason to accept the conclusion, even though the effort is not related to the truth.

Flat-Earthers would often over-emphasize their efforts in proving a flat earth and belittling that from ‘globe-earthers’. Then they take the purported noteworthiness of their efforts to conclude that the Earth is flat. This is the fallacy of notable effort. Putting in more effort does not mean the conclusion is more correct.

Special Pleading

Special pleading is applying standards, principles, or rules to other people or circumstances, while making themselves or certain circumstances exempt from the same critical criteria, without providing adequate justification.

Flat-Earthers like to impose various unwarranted rules and conditions —that were invented spontaneously— to rule out evidence against flat Earth. However, when it comes to the things they regard as ‘evidence’ in favor or a flat Earth, they are more than happy to ignore the rules and conditions that they previously invented.

False Analogy

A false analogy is a fallacy in which similarity in one respect of two concepts, objects, or events is taken as sufficient to establish that they are similar in another respect in which they are actually are not similar.

Almost all of what flat-Earthers happily claim as “experiments” are actually false analogies. They would take everyday objects and use them as analogies for actual objects. In reality, a shared similarity in both the analogy and the real thing is not sufficient to ‘prove’ both are similar in some other respect.

False Dichotomy

A false dichotomy or false dilemma is a logical fallacy which involves presenting two opposing views, options, or outcomes in such a way they seem to be the only possibilities: if one is true, then the other must be false. In reality, there can be many in-between or other alternative options, not just two mutually exclusive ones.

Flat-Earthers like to ‘disprove’ spherical Earth using their own ignorance about various issues. Then they would regard their erroneous belief that spherical Earth has been disproven as “proof” that the Earth is flat. This is fallacious reasoning because the Earth can be in another shape instead.

Einstein’s Thought Experiments and Daydreaming

Albert Einstein used thought experiments as a tool for formulating his theories. His theories provided predictions that can be tested in observation and experiments. He did not perform the observation and experiments himself. Others did and confirmed his theories.

Some flat-Earthers dismiss Einstein’s theories —especially those about gravity— on the basis that they are founded on thought experiments and daydreaming. They are wrong. His theories have been repeatedly confirmed by various experiments and observation performed by many others, even to this day.

Photographic Evidence

A photograph alone is not sufficient to prove that the things or event in the photo is real. The reality of the things or event needs to be determined using inductive reasoning, where multiple information is considered and evaluated together.

Flat-Earthers often claim that we regard certain things or events as real only from photographic evidence. In reality, there is information other than the photographs themselves that was considered and led us to accept the things or events are real beyond any reasonable doubt.

Shifting of the Burden of Proof

The fallacy of shifting of the burden of proof is committed when someone makes a claim that requires justification, failed to provide sufficient evidence, but instead demand others to provide the evidence of the opposite of their claim.

Most of the claims from flat-Earthers are bare assertions. They do not provide sufficient evidence. A false way for them to defend their claims is by shifting the burden of proof.

Appeal to Possibility

The fallacy of appeal to possibility occurs when a conclusion is assumed not because it has been proven, but because it is possible that it is true, no matter how improbable. Flat-Earthers would often use this fallacious reasoning to prevent their theories from being falsified. In particular, to “disprove” photos and videos taken from space.

“Behind the Curve”: the Earth’s Curvature Experiment

Featured Video Play Icon

“Behind the Curve” is a documentary showing behind the scenes on what is happening in the flat-Earth community in the United States just before a flat-Earth conference. In a section, the film shows us how a flat-Earther tried to disprove curvature using a series of visual experiments. The result clearly indicates the surface curves, but he was unwilling to accept the fact.

“Behind the Curve” is a documentary showing behind the scenes on what is happening in the flat-Earth community in the United States just before a flat-Earth conference. In a section, the film shows us how a flat-Earther did an experiment involving a ring laser gyroscope, which proved the very thing he tried to disprove: Earth’s rotation; and that he was unwilling to accept the result.

One Single Proof Fallacy

The fallacy of “one single proof” occurs when someone rejects overwhelming evidence because of the lack of specific evidence and declare the entire argument invalid.

A common trick of flat-Earthers is to demand unrealistic evidence of spherical Earth. After their demand is not met, they would proclaim Earth is not a sphere, and conveniently ignore all the other evidence of spherical Earth.

Fiber-Optic vs Satellite Communication

Fiber-optic communication is a method of transmitting data by sending pulses of light through an optical fiber. These days, the majority of data communication involves a fiber-optic connection. However, other methods of transmitting data exist, including satellites.

Flat-Earthers use the prominence of fiber-optic communication as “proof” of the nonexistence of satellites. Such a line of thinking is a fallacy of hasty generalization. Using the same “logic,” we can “prove” trains don’t exist just by showing the existence of cars.

Composite Photos of the Earth

NASA has published several pictures of the Earth that are composites. It means the pictures were the result of combining many images into a single picture. In most cases, the source pictures were taken from low-orbiting satellites to obtain higher resolution pictures of the Earth.

Flat-Earthers discovered the photos are composites and claimed to have exposed “yet another evidence” of wrongdoing. They would publish this “findings” everywhere to turn us emotional. They are wrong. Nobody is covering the fact the pictures are composites, and there is no intention to deceive. Information that the photos are composites can be readily found in NASA’s website, far before the claimed “discovery” by flat-Earthers.

Theories of Gravity

Gravity is a natural phenomenon by which all things with mass or energy are brought toward one another. Today, the phenomenon of gravity is explained by two theories: Newton’s law of universal gravitation and Einstein’s general relativity.

Flat-Earthers take the existence of the two explanations as inconsistency in science and use it as a “proof” of deliberate misconduct. Such allegation is obviously only a result of their prejudice. The two theories are the correct explanations of gravity, and can reliably predict the outcome of the phenomenon.

Proofs of Spherical Earth Presented by Flat-Earthers

Many adherents of flat Earth have spent a lot of effort and money to perform various observations and experiments. They would buy expensive equipment, travel to the other side of the world, painstakingly designed the experiments in minute details, and performed large-scale experiments; all to prove the notion that Earth is flat. However, many of these experiments and observations have actually confirmed the Earth is a sphere beyond any doubt.

In most cases, they would not accept such conclusions, and instead, they misinterpret, refuse to accept, lie, and withhold information. Such behaviors are the results of confirmation bias. However, their results speak louder than their biased conclusions, and these are perfectly valid proofs that Earth is a sphere.

These are some of those observations and experiments, where flat-Earthers have painstakingly and extravagantly performed them, only to come up with the wrong conclusions and spectacularly demonstrating their confirmation biases to the entire world.

Stellarium

Some flat-Earthers like to observe celestial phenomena and the positions of celestial objects. Sometimes, they insist such events cannot possibly happen if the Earth is a sphere orbiting the Sun, and took the wrong conclusion that the Earth must be flat.

We can try asking them the time of the occurrence and the position of the observer, then use Stellarium or similar applications to simulate it. If the result matches the observation, then they have nothing to complain about. Their confusion was only the result of their ignorance.

How to “Prove” a Basketball (or any Spherical Object) is Flat

If we were to magnify the surface of any spherical object with large enough magnification, then at some point, it would appear flat. This can be easily demonstrated using a macro lens as the Redditor ‘Useless-Pickles’ did. He magnified the surface of a basketball using an extreme macro lens as a philosophical demonstration.

This shows that the surface of a spherical object can easily look flat if the object is large enough, or the observer is small enough.  And the basis of all flat-Earthers’ belief that the horizon appears flat is insufficient to determine the shape of the Earth. By applying the same “logic” as these flat-Earthers, we can actually “prove” a basketball is flat, which, as we all know, is clearly wrong.
