60. Repeats that the horizon always appears flat

“Anyone can prove the sea-horizon perfectly straight and the entire Earth perfectly flat using nothing more than a level, tripods and a wooden plank. At any altitude above sea-level, simply fix a 6-12 foot long, smooth, leveled board edgewise upon tripods and observe the skyline from eye-level behind it. The distant horizon will always align perfectly parallel with the upper edge of the board. Furthermore, if you move in a half-circle from one end of the board to the other whilst observing the skyline over the upper edge, you will be able to trace a clear, flat 10-20 miles depending on your altitude. This would be impossible if the Earth were a globe 25,000 miles in circumference; the horizon would align over the center of the board but then gradually, noticeably decline towards the extremities. Just ten miles on each side would necessitate an easily visible curvature of 66.6 feet from each end to the center.”


This is the same as proof 1 but with a suggested experiment.

The experiment is of course simplistic and relying on inaccurate observations by eye.  The key to understanding this is to realise that the Earth so huge that any curvature would obviously not be observable especially with our very limited field of vision.

See proof 1 for a more detailed response.

127. Straight reflections of sunlight and moonlight are impossible on a spherical Earth

Image
"The fact that the Sun and Moon’s reflections on water always form a straight line path from the horizon to the observer proves the Earth is not a ball. If Earth’s surface was curved it would be impossible for the reflected light to curve over the ball from horizon to observer." This is a flawed argument because Dubay does not understand how reflections operate Although he doesn't describe it very well, I presume that Dubay is referring to the angle of reflection from a curved surface.  I.e. the curve of the Earth would mean that the angle of reflection off the surface would result in nearly all the light  not reaching the observer's eyes. The fact that, if this was how reflections worked, that the same would be true on a flat Earth seems to have escaped Dubay's notice. This type of reflection is called specular reflection, and takes place with mirror like surfaces.  Generally the surface of the water is not perfectly flat so the reflection of the light...

Debunking Eric Dubay's 200 proofs the earth is not a spinning ball

Image
Conspiracy Baloney aims to provide resources to counter to the influence of the crazy anti-science conspiracy theories that are out there. This blog is specifically to debunk Eric Dubay's " 200 proofs the earth is not a spinning ball", that I have found flat earthers often cite. There are quite a few resources out there that comprehensively debunk this book, but I think that one more voice can only help.  I have tried to keep the rebuttals as non technical as possible. Eric Dubay’s proofs are laughably simplistic and demonstrate an almost complete lack of understanding of maths and anything scientific or technical. A list of "proofs" that show Dubay is an idiot He also likes to give historical quotes as proofs.  Typical are quotes from the 1800’s but he even has one from before 1600!.  Not only are these opinions not proof of anything, but the fact that he can’t provide quotes from more up to date sources destroys their credibility. Worse, ...

If Earth was a sphere the visible stars would be different

Image
The visible stars are a big problem for flat Earthers because what we observe is 100% consistent with a spherical Earth and completely impossible on a flat Earth. Their solution?  Simply to lie about what is observed.  These lies include denials of observations that are impossible on a flat Earth and pretending that observed stars would be impossible on spherical Earth. For the latter, it could be that Dubay simply can't do simple trigonometry but I think that he is once again deliberately lying. The strange thing about this is that everyone is capable of putting these claims to the test simply by looking up at the night sky.  The fact that flat Earth believers refuse to put these "proofs" to the test tells you that they are not really interested in truth, they are only interested in feeling good about their beliefs and will simply unquestioningly accept as fact anything that backs up these beliefs. Ignorance truly is bliss. 99...
