8. The 100 mile Suez canal was dug horizontally without taking the Earths curvature into account


“The Suez Canal connecting the Mediterranean with the Red Sea is 100 miles long without any locks making the water an uninterrupted continuation of the two seas. When constructed, the Earth’s supposed curvature was not taken into account, it was dug along a horizontal datum line 26 feet below sea-level, passing through several lakes from one sea to the other, with the datum line and water’s surface running perfectly parallel over the 100 miles.”


Dubay lacks an understanding of what "horizontal" and "sea level" means

The implication is that if the canal was dug horizontally it could not follow the curve of the earth.  As explained in response to proof 4, “Down” is defined by the direction of gravity which is towards the centre of the earth.  Horizontal is perpendicular to this.  This means that to be horizontal means to follow the curve of the earth.  Similarly sea level stays the same distance from the centre of the earth, so it too follows the curve of the earth.  Digging horizontally and keeping 26 feet below sea level means that you are following the curve of the earth, just like the sea does.

Was the curvature of the earth actually used by the surveyors?  Probably, but even if it wasn’t I bet that I could do a pretty good job simply by making adjustments after measuring the water level as each new section of the canal was finished.  Since they would know that the water will always be at sea level in each new section as it is completed, if the water depth is slightly less than 26 feet I know do dig a little deeper for the next section.  It is not as if a canal needs to be precision engineered.

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

"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,

9. Engineer W Winckler was published in the Earth Review in 1893 arguing that no engineer took the curvature of the earth into account

“Engineer, W. Winckler was published in the Earth  Review regarding the Earth’s supposed curvature, stating,   “As an engineer of many years standing , I saw that this  absurd allowance is only permitted in school books.  No  engineer would dream of allowing anything of the kind.  I  have projected many miles of railways and many more of  canals and the allowance has not even been thought of  much less allowed for. This allowance for curvature means  this - that it is 8 ” for the first mile of a canal, and increasing  at the ratio by the square of the distance in miles; thus a  small navigable canal for boats, say 30 miles long, will  have, by the above rule an allowance for curvature of 600  feet. Think of that and then please credit engineers as not  being quite such fools. Nothing of the sort is allowed. We  no more think of allowing 600 feet for a line of 30 miles of  railway or canal, than of wasting our time trying to square  the circle ”" This is a historical opinion,
