27. On a fast spinning Earth airplanes landing on runways would be practically impossible

“If Earth and its atmosphere were constantly spinning Eastwards over 1000 mph, landing airplanes on such fast-moving runways which face all manner of directions North, South, East, West and otherwise would be practically impossible, yet in reality such fictional concerns are completely negligible.”

This is a repeat of proof 24.  Again Dubay shows that he does not understand relative motion.

Taking this step by step for Mr Dubay ....














Yes, the tangential speed of the Earth and runway (at the equator) is over 1000 mph, BUT as the “proof” admits, so is the atmosphere.

The plane is flying within the moving atmosphere.  A plane flying at the typical landing speed of say 160 miles per hour, is flying at 160 miles per hour relative to the atmosphere whichever direction it is facing.

Because the atmosphere is moving with the ground and runway (i.e. both at over 1000 miles per hour) this means that the plane is flying at 160 miles per hour relative to the ground and runway whichever direction it is facing.

So when the plane lands on the runway, the only speed it needs concern itself with is its own 160 miles per hour …. Whichever direction it is facing.

So yes, these concerns are fictional.  A fiction made up by Eric Dubay.

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, ...

1. The horizon always appears flat

Image
“The horizon always appears perfectly flat 360 degrees around the observer regardless of altitude. All amateur balloon, rocket, plane and drone footage show a completely flat horizon over 20+ miles high. Only NASA and other government “space agencies” show curvature in their fake CGI photos/videos.” Lazy thinking Our eyes are forward facing, with a very narrow field of vision.  While we can detect things in our peripheral vision what we see is very vague.  However we “feel” that we see a lot more than we do because our mind builds a more panoramic picture for us. Source:  https://www.eyehealthweb.com/peripheral-vision/ Think of the panoramic picture Apps that you can get for smartphones.  You take a narrow picture, then turn and take another and repeat.  The App then stitches these pictures together into one panoramic picture.  For us, our eyes are constantly moving left and right and it is our brain that is stitching together ...
