153. Dubay quotes Reverend Thomas Milner giving examples of really flat parts of the Earth

Image
"Quoting Reverend Thomas Milner’s “Atlas of Physical Geography,” we find that, “ Vast areas exhibit a perfectly dead level, scarcely a rise existing through 1,500 miles from the Carpathians to the Urals. South of the Baltic the country is so flat that a prevailing north wind will drive the waters of the Stattiner Haf into the mouth of the Oder, and give the river a backward flow 30 or 40 miles. The plains of Venezuela and New Granada, in South America chiefly on the left of the Orinoco, are termed llanos, or level fields. Often in the space of 270 square miles the surface does not vary a single foot. The Amazon only falls 12 feet in the last 700 miles of its course; the La Plata has only a descent of one thirty-third of an inch a mile.”" Duh! On a spherical Earth, "flat" obviously follows the curve of the Earth.  Yes there are lots of flat places.  The Earth is still a sphere. < Prev      151-160     Next >

11. Railways can’t go over the “hump” caused by the curve of the Earth

Image
“A  surveyor and engineer of thirty years published in the Birmingham Weekly Mercury stated, “I am thoroughly acquainted with the theory and practice of civil engineering. However bigoted some of our professors may be in the theory of surveying according to the prescribed rules, yet it is well known amongst us that such theoretical measurements are INCAPABLE OF ANY PRACTICAL ILLUSTRATION. All our locomotives are designed to run on what may be regarded as TRUE LEVELS or FLATS. There are, of course, partial inclines or gradients here and there, but they are always accurately defined and must be carefully traversed. But anything approaching to eight inches in the mile, increasing as the square of the distance, COULD NOT BE WORKED BY ANY ENGINE THAT WAS EVER YET CONSTRUCTED. Taking one station with another all over England and Scotland, it may be stated that all the platforms are ON THE SAME RELATIVE LEVEL. The distance between Eastern and Western coasts of England may be set down as 3...

10. Following the curve of the Earth changes your elevation above sea level

Image
“The London and Northwestern Railway forms a straight line 180 miles long between London and Liverpool. The railroad’s highest point, midway at Birmingham station, is only 240 feet above sea-level. If the world were actually a globe, however, curving 8 inches per mile squared, the 180 mile stretch of rail would form an arc with the center point at Birmingham raising over a mile, a full 5,400 feet above London and Liverpool.” Dubay does not understand basic geometry, what elevation is or how it is measured Imagining a line drawn from London to Liverpool on a spherical earth, and then measuring the height of the hump at the mid point formed by the curvature of the earth has absolutely nothing to do with height above sea level.  Sea level follows the curve of the earth because the sea is maintaining an equal distance from the centre of the earth. Note also that the London and North Western railway ceased to exist in 1922.  It seems Eric Dubay likes to rely on sources ...

5. If Earth were sphere that would mean that the Nile would sometimes be running uphill

Image
“One portion of the Nile River flows for a thousand miles with a fall of only one foot. Parts of the West African Congo, according to the supposed inclination and movement of the ball-Earth, would be sometimes running uphill and sometimes down. This would also be the case for the Parana, Paraguay and other long rivers.” Dubay does not understand elevation and laws of motion. I presume that the “inclination” part again refers to rivers flowing over the “hump” which has been dealt with the response to proof 4 .  The “motion” part probably refers to the spin of the Earth pushing the water uphill.  This also has been dealt with in the response to proof 3 . Eric Dubay is a liar As an aside he also claims that the Nile drops only 1 foot in 1000 miles is a blatant lie. See the Nile elevation chart below.  I only point this out to show that he does not hesitate to lie to make his points.

4. If Earth were sphere that would mean that some rivers are running uphill

Image
“Rivers run down to sea-level finding the easiest course, North, South, East, West and all other intermediary directions over the Earth at the same time. If Earth were truly a spinning ball then many of these rivers would be impossibly flowing uphill, for example the Mississippi in its 3000 miles would have to ascend 11 miles before reaching the Gulf of Mexico.” Dubay does not understand what elevation above sea level is I don’t know where Dubay got his 11 mile figure from since he does not explain it, but I presume that it is to do with the curve of the Earth creating a hump over which the water has to travel. Imagine a line from one location on Earth to another.  On a spherical Earth the mid point has a “hump” above the line caused by the curvature of the Earth’s surface.   Eric Dubay thinks that this hump is equivalent to elevation and that you would need to travel up hill as you moved over the hump. This is not how elevation works. Gravity exerts a force...
