10) Ship captains in navigating great distances at sea never need to factor the supposed curvature of the Earth into their calculations. Both Plane Sailing and Great Circle Sailing, the most popular navigation methods, use plane, not spherical trigonometry, making all mathematical calculations on the assumption that the Earth is perfectly flat. If the Earth were in fact a sphere, such an errant assumption would lead to constant glaring inaccuracies. Plane Sailing has worked perfectly fine in both theory and practice for thousands of years, however, and plane trigonometry has time and again proven more accurate than spherical trigonometry in determining distances across the oceans. If the Earth were truly a globe, then every line of latitude south of the equator would have to measure a gradually smaller and smaller circumference the farther South travelled. If, however, the Earth is an extended plane, then every line of latitude south of the equator should measure a gradually larger and larger circumference the farther South travelled. The fact that many captains navigating south of the equator assuming the globular theory have found themselves drastically out of reckoning, more so the farther South travelled, testifies to the fact that the Earth is not a ball.
As the mariners' compass points north and south at one time, and as the North, to which it is attracted is that part of the Earth situated where the North Star is in the zenith, it follows that there is no south "point" or "pole" but that, while the centre is North, a vast circumference must be South in its whole extent. This is a proof that the Earth is not a globe.
Imagine an ant walking along the surface of an orange, into your field of view. If you look at the orange “head on”, you will see the ant’s body slowly rising up from the “horizon” because of the curvature of the orange. If you would do that experiment with the ant approaching along a long road rather than a round object, the effect would change: The ant would slowly "materialize" into view (depending on how sharp your vision is).
The Rev. D. Olmsted, in describing a diagram whish is supposed to represent the Earth as a globe, with a figure of a man sticking out at each side and one hanging head downwards, says "We should dwell on this point until it appears to us as truly up," In the direction given to these figures as it does with regard to a figure which he has placed on the top! Now, a system of philosophy which requires us to do something which is, really, the going out of our minds, by dwelling on an absurdity until we think it is a fact, Cannot be a system based on God's truth, which never requires anything of the kind. Since, then, the popular theoretical astronomy of the day requires this, it is evident that it is the wrong thing, and that this conclusion furnishes us with a proof that the Earth is not a globe.
While it's true that unipolar magnets can't exist, this isn't a problem for the Flat Earth. This is because ring magnets, which are shaped like (you guessed it!) a flat disk, are capable of having radial magnetization. In a radial magnet, one magnetic pole is at the center and other is at all points on the edge of the magnet. A magnet like this can be found in loudspeakers, and perfectly replicates what is found on the Earth.

102) Some heliocentrists have tried to suggest that the Pole Star’s gradual declination overhead as an observer travels southwards is proof of a globular Earth. Far from it, the declination of the Pole Star or any other object is simply a result of the Law of Perspective on plane (flat) surfaces. The Law of Perspective dictates that the angle and height at which an object is seen diminishes the farther one recedes from the object, until at a certain point the line of sight and the seemingly uprising surface of the Earth converges to a vanishing point (i.e. the horizon line) beyond which the object is invisible. In the ball-Earth model the horizon is claimed to be the curvature of the Earth, whereas in reality, the horizon is known to be simply the vanishing line of perspective based on the strength of your eyes, instruments, weather and altitude.
So, before God created land and all living things, “darkness was on the face of the deep,” a large expansive ocean. Water does not curve. In its resting state, the surface of a body of water always remain level, hence, it describes it as the “face of the deep.” It is true that small amounts of water may “curve” because of surface tension, and larger amounts of water move and “curve” when disturbed. But, the surface of all resting water is always level, flat. It does not matter how curved or rough the land is below the water.

Satan is programming the world to believe in everything that is opposite of the Bible. In the Globe earth model the sun is the center of the Universe, but the Bible never refers to the earth moving around the sun. The Bible says instead, that the earth is stable, on a firm foundation, and cannot be moved (1 Chronicle 16:30; Psalm 93:1; Psalm104:5).
198) Some say the idea of an inter-generational world-wide conspiracy to delude the masses sounds implausible or unrealistic, but these people need only familiarize themselves with the works and writings of Freemasons themselves, for example John Robison who exposed this in his 1798 book, “Proofs of a Conspiracy Against All the Religions and Governments of Europe Carried Out in the Secret Meetings of the Freemasons, Illuminati and Reading Societies.” Supreme Commander of the 33rd degree Albert Pike was quite forth-coming in several letters regarding the Masons ultimate goal of world domination, and in the Zionist “Protocols of the Learned Elders of Zion” the exact plan by which this would be and has been carried out is completely disclosed.

131) NASA and modern astronomy maintain that the Moon is a solid, spherical, Earth-like habitation which man has actually flown to and set foot on. They claim the Moon is a non-luminescent planetoid which receives and reflects all its light from the Sun. The reality is, however, that the Moon is observably not a solid body, it is clearly circular, but not spherical, and not in any way an Earth-like planetoid which humans could set foot on. In fact, the Moon has been proven largely transparent and completely self-luminescent, shining with its own unique light.
If the Moon is a disc which faces us and whose orientation can be explained, for instance, as the head of a tennis racket as someone holds it out and turns, thus the same side of the head always faces to the inside of the circle path it travels, and if this disc faces down all the time on our FE, what purpose the craters and how did they get there?
As mariners take to sea with them charts constructed as though the sea were a level surface, however these charts may err as to the true form of this level surface taken as a whole, it is clear, as they find them answer their purpose tolerably well - and only tolerably for many ships are wrecked owing to the error of which we speak - that the surface of the sea is as it is taken to be, whether the captain of the ship "supposes" the Earth to be a globe or anything else. Thus, then, we draw, from the common system of "plane sailing," a practical proof that Earth is not a globe.
The Flat Earth Society is a group actively promoting the Flat Earth Movement worldwide. Descending from Samuel Shenton's International Flat Earth Research Society, and the Universal Zetetic Society before it, we continue the age-old tradition of questioning the Round Earth doctrine and challenging authorities. Acknowledging the link between various unconventional beliefs, the Society also occasionally engages in other unconventional debates, striving to provide a voice for all free thinkers and Zeteticists.

96) From “100 Proofs the Earth is Not a Globe” by William Carpenter, “If we take a journey down the Chesapeake Bay, by night, we shall see the ‘light’ exhibited at Sharpe's Island for an hour before the steamer gets to it. We may take up a position on the deck so that the rail of the vessel's side will be in a line with the ‘light’ and in the line of sight; and we shall find that in the whole journey the light won't vary in the slightest degree in its apparent elevation. But, say that a distance of thirteen miles has been traversed, the astronomers' theory of ‘curvature’ demands a difference (one way or the other!) in the apparent elevation of the light, of 112 feet 8 inches! Since, however, there is not a difference of 100 hair's breadths, we have a plain proof that the water of the Chesapeake Bay is not curved, which is a proof that the Earth is not a globe.”

20. The common sense of man tells him - if nothing else told him - that there is an "up" and a "down" in -nature, even as regards the heavens and the earth; but the theory of modern astronomers necessitates the conclusion that there is not: therefore, 'the theory of the astronomers is opposed to common sense - yes, and to inspiration - and this is a common sense proof that the Earth is not a globe
