We get this video a lot, so I thought I'd make an easily found thread debunking it. If a mod could sticky this that would be awesome.



1. Other planets are round



According to Flat Earth Theory, the Earth and other planets are not really the same type of celestial body. To put it another way, which I'm sure everyone everywhere will take offense to, the Earth is different.



2. Time Zones



This is the first of a trend in this video, in which Henry (the host of MinutePhysics, for those not subscribed) assumes that the Flat Earth is exactly the same as the Round Earth in every way except for shape. The sun works in a manner similar to a spotlight in Flat Earth Theory, which is why time zones exist. When the Sun isn't pointing overhead, it's nighttime.



3. The Coriolis Effect



Once again, Henry is making assumptions. There are a few differing opinions about this, as Flat Earth Theory is not a unified theory. Some people doubt the existence of Coriolis as anything more than a theorized force, as the evidence for it is largely contrived. Others have various explanations for it, such as the Shadow of the Aetheric Wind theorized by myself.



4. Triangles



This is little more than conjecture. It is literally impossible to perform this experiment on the scale required.



5. The Sun



Henry is assuming again. The Sun's apparent movement is caused by the Sun actually moving. As for Eratosthenes's famous experiment to measure the diameter of the Earth, that assumes a Round Earth. If we assume a Flat Earth, the same experiment gives us the distance to the Sun.



6. Stars Change



Another assumption. This time, he's assuming that FE geography is just a Mercator map. It's not. The Earth is a disk centered around the North Pole, which would provide the same effect.



7. Magellan



Again, the Earth isn't in the shape of a Mercator map. That would be silly. Magellan and many others simply made a circle around the disk of the Earth.



8. The Horizon



This is just a perspective effect. First of all, apparently large waves will obscure apparently small objects. Therefore, looking out long distances over water you will of course be unable to see land on the other side. In addition, refraction has an effect. Some flat Earthers theorize an electromagnetic acceleration which appears to bend light upward.



9. Eclipses



Eclipses are caused by the sun going behind the moon, or vice versa. It's that simple. Once again, Henry is assuming everything is exactly the same.



10. Photographic Evidence



Most photographic evidence actually demonstrates what we would expect to see on a disk shaped, flat Earth: a circle with little to no apparent curvature. Add in camera distortion, and that's our explanation for low Earth photos. As for photos like the famous Blue Marble, that the space agencies of the World are involved in a conspiracy is depressingly obvious if you look at the evidence.



____



I'd appreciate it if you didn't respond to this thread, or if a mod locked it. It's not up for discussion. This is just to let newcomers know that they can't 'destroy FES with a single video' as so many hope to. It's not that easy. Sorry.



Seriously, this isn't a debate thread. If you want to debate it, feel free to make a new thread. I'm not responding to questions or concerns in this one.
