Standing Water is Flat Water
It is part of the natural physics of water and other fluids to always find their level and remain flat. If disturbed in any way, motion ensues until the flat level is resumed. If dammed up then released, the nature of all liquids is to quickly flood outwards taking the easiest course towards finding its new level.
“The upper surface of a fluid at rest is a horizontal plane. Because if a part of the surface were higher than the rest, those parts of the fluid which were under it would exert a greater pressure upon the surrounding parts than they receive from them, so that motion would take place amongst the particles and continue until there were none at a higher level than the rest, that is, until the upper surface of the whole mass of fluid became a horizontal plane.” -W.T. Lynn, “First Principles of Natural Philosophy”
If the Earth is an extended flat plane, then this fundamental physical property of fluids finding and remaining level is consistent with experience and common sense. If, however, the Earth is a giant sphere tilted on its vertical axis spinning through never-ending space then it follows that truly flat, consistently level surfaces do not exist here! Moreover, if the Earth is spherical then it follows that the surface of all Earth’s water, including the massive oceans, must maintain a certain degree of convexity. But this is contrary to the fundamental physical nature of water to always be and remain level!
“The surface of all water, when not agitated by natural causes, such as winds, tides, earthquakes etc. is perfectly level. The sense of sight proves this to every unprejudiced and reasonable mind. Can any so-called scientist, who teaches that the earth is a whirling globe, take a heap of liquid water, whirl it round, and so make rotundity? He cannot. Therefore it is utterly impossible to prove that an ocean is a whirling rotund section of a globular earth, rushing through ‘space’ at the lying-given-rate of false philosophers.” -William Thomas Wiseman, “The Earth An Irregular Plane”
If we were living on a whirling ball-Earth, every pond, lake, marsh, canal and other large body of standing water, each part would have to comprise a slight arc or semi-circle curveting downwards from the central summit. For example, if the ball-Earth were 25,000 miles in circumference as NASA and modern astronomers say, then spherical trigonometry dictates the surface of all standing water must curve downwards an easily measureable 8 inches per mile multiplied by the square of the distance. This means along a 6 mile channel of standing water the Earth would dip 6 feet on either end from the central peak. To the benefit of true science, and to the detriment of modern astronomy’s pseudo-science, such an experiment can and has been tested.
In Cambridge, England there is a 20 mile canal called the Old Bedford which passes in a straight line through the Fenlands known as the Bedford Level. The water has no interruption from locks or water-gates of any kind and remains stationary making it perfectly suitable for determining whether any amount of convexity/curvature actually exists. In the latter part of the 19th century, Dr. Samuel Rowbotham, a famous Flat-Earther and author of the fine book, “Earth Not a Globe! An Experimental Inquiry into the True Figure of the Earth: Proving it a Plane, Without Axial or Orbital Motion; and the Only Material World in the Universe!” travelled to the Bedford level and performed a series of experiments to determine whether the surface of standing water is flat or convex.
“A boat, with a flag-staff, the top of the flag 5 feet above the surface of the water, was directed to sail from a place called ‘Welche’s Dam’ (a well-known ferry passage), to another called ‘Welney Bridge.’ These two points are six statute miles apart. The author, with a good telescope, went into the water; and with the eye about 8 inches above the surface, observed the receding boat during the whole period required to sail to Welney Bridge. The flag and the boat were distinctly visible throughout the whole distance! There could be no mistake as to the distance passed over, as the man in charge of the boat had instructions to lift one of his oars to the top of the arch the moment he reached the bridge. The experiment commenced about three o’clock in the afternoon of a summer’s day, and the sun was shining brightly and nearly behind or against the boat during the whole of its passage. Every necessary condition had been fulfilled, and the result was to the last degree definite and satisfactory. The conclusion was unavoidable that the surface of the water for a length of six miles did not to any appreciable extent decline or curvate downwards from the line of sight. But if the earth is a globe, the surface of the six miles length of water would have been 6 feet higher in the centre than at the two extremities. From this experiment it follows that the surface of standing water is not convex, and therefore that the Earth is not a globe! On the contrary, this simple experiment is all-sufficient to prove that the surface of the water is parallel to the line-of-sight, and is therefore horizontal, and that the Earth cannot be other than a plane!” -Dr. Samuel Rowbotham, “Zetetic Astronomy, Earth Not a Globe! An Experimental Inquiry into the True Figure of the Earth: Proving it a Plane, Without Axial or Orbital Motion; and the Only Material World in The Universe!” (12-13)
In a second experiment, Dr. Rowbotham placed seven flags along the edge of the water each one mile distant from the next with their tops positioned 5 feet above the surface. Near the last one he also positioned a longer, 8 foot staff bearing a 3 foot flag so that its bottom aligned precisely with the tops of the other flags. He then mounted a telescope at a height of 5 feet behind the first flag and took his observations. If the Earth was a globe of 25,000 miles, each successive flag would have to decline a definite and determined amount below the last. The first and second flags simply established the line of sight, the third flag should then fall 8 inches below the second, the fourth flag 32 inches below, the fifth 6 feet, the sixth 10 feet 8 inches, and the seventh flag should be a clear 16 feet 8 inches below the line of sight! Even if the Earth was a globe of a hundred thousand miles, an amount of easily measurable curvature should and would still be evident in this experiment. But the reality is not a single inch of curvature was detected and the flags all lined up perfectly as consistent with a flat plane.
“The rotundity of the earth would necessitate the above conditions; but as they cannot be found to exist, the doctrine must be pronounced as only a simple theory, having no foundation in fact--a pure invention of misdirected genius; splendid in its comprehensiveness and bearing upon natural phenomena; but, nevertheless, mathematical and logical necessities compel its denunciation as an absolute falsehood.” -Dr. Samuel Rowbotham, “Zetetic Astronomy, Earth Not a Globe!” (14)
