Organisations claimed to conspire are too new
2023-11-07 10:35 Many flat-earthers claim the round Earth to be a hoax by the Freemasons.  How long to they think the Freemasons have existed, maybe 3,000 years?  I would rather say 300.
The frozen continent of Antarctica
2023-11-03 10:57 Antarctica is a continent lying around the South Pole.  However, it is not particularly symmetrical.  There is considerably less land in the direction of South America and the Pacific.
On space and telescopes
2023-11-01 12:23 Most flat-earthers claim that space don’t exist.  Oftentimes this is about a misunderstanding of the concept of vacuum.  The “vacuum” people are familiar with from contact with everyday objects is actually an under-pressure.
Consequences of the Earth’s motions
2023-10-27 11:07 Regardless if they are flat-earthers or not some denies that the Earth moves.  The argument is we would feel it.  The problem with this argument is we don’t feel movement in and of itself.
Flying with gravity
2023-10-25 11:09 Flat-earthers usually claim that gravity does not exist.  It is claimed to be incompatible with how things fly.  If gravity makes things fall down everything is supposed to always fall down.
On maps and navigation
2023-10-19 13:00 Flat-earthers use to claim the world looks like this...
What you can in fact see in the sky
2023-10-17 11:09 Flat-earthers show great ignorance about the movements of celestial bodies.  It is bad enough to believe that perspective could explain the sun rising and setting.
How far can you see?
2023-10-11 10:36 Flat-earthers like to argue that one can see things further away than one would on a round Earth.  The problem is usually faulty calculations of what one would be able to see.
Perspective in real life
2023-10-10 10:41 Something flat-earters have substantially misunderstood is the concept of perspective.  It is not a natural law for light.  Instead, it is a method for depicting things on a flat surface.
Mathematics works!
2023-10-05 12:31 Many people certainly hate math.  I think this is due to misdirected attempts to increase the number of mathematicians.  They tried to teach advanced concepts to everyone from an early age.
