A flat planet (ours or any other planet) would be such an incredible observation that it would pretty much go against everything we know about how planets form and behave. It would not only change everything we know about planet formation, but also about star formation (our sun would have to behave quite differently to accommodate the flat-earth theory) and what we know of speeds and movements in space (like planets' orbits and the effects of gravity). In short, we don’t just suspect that our planet is spherical. We know it.
72.) Astronomers tell us that, in consequence of the Earth's "rotundity," the perpendicular walls of buildings are, nowhere, parallel, and that even the walls of houses on opposite sides of a street are not! But, since all observation fails to find any evidence of this want of parallelism which theory demands, the idea must be renounced as being absurd and in opposition to all well-known facts. This is a proof that the Earth is not a globe.
115) The existing laws of density and buoyancy perfectly explained the physics of falling objects long before knighted Freemason “Sir” Isaac Newton bestowed his theory of “gravity” upon the world. It is a fact that objects placed in denser mediums rise up while objects placed in less dense mediums sink down. To fit with the heliocentric model which has no up or down, Newton instead claimed objects are attracted to large masses and fall towards the center. Not a single experiment in history, however, has shown an object massive enough to, by virtue of its mass alone, cause other smaller masses to be attracted to it as Newton claims “gravity” does with Earth, the Sun, Moon, Stars and Planets.
69) The New York City skyline is clearly visible from Harriman State Park’s Bear Mountain 60 miles away. If Earth were a ball 25,000 miles in circumference, viewing from Bear Mountain’s 1,283 foot summit, the Pythagorean Theorem determining distance to the horizon being 1.23 times the square root of the height in feet, the NYC skyline should be invisible behind 170 feet of curved Earth.
I have been an advocate for the flat earth for months thanks to your research. I have been debating my family and even got grounded by my parents a couple times when i lost my patience (I was still in high school at the time). I have weakened relationships and even lost friends all together because of my need to show those around me the truth. I completely believe the earth is flat and want to spread the message as much as possible. I have downloaded and printed multiple copies of your 200 proof book and dispersed them to my friends and even their parents. I am letting you know this because i was banned from The International Flat Earth Research Society i believe twice now. I either created a thread when i shouldn't have or an admin took me as a shill. I even messaged you a couple months ago about an introduction, math proof, and index i made to supplement your 200 proof book. This all being said i can not allow myself to be banned from the forum as i need to learn more. Please do not ignore this message and help me someway be able to access the forum again.
95) On a clear day from the highland near Douglas Harbor on the Isle of Man, the whole length of the coast of North Wales is often plainly visible to the naked eye. From the Point of Ayr at the mouth of the River Dee to Holyhead comprises a 50 mile stretch which has also been repeatedly found to be perfectly horizontal. If the Earth actually had curvature of 8 inches per mile squared, as NASA and modern astronomy claim, the 50 mile length of Welsh coast seen along the horizon in Liverpool Bay would have to decline from the center-point an easily detectable 416 feet on each side!
The idea that, instead of sailing horizontally round the Earth, ships are taken down one side of a globe, then underneath, and are brought up on the other side to get home again, is, except as a mere dream, impossible and absurd! And, since there are neither impossibilities nor absurdities in the simple matter of circumnavigation, it stands without argument, a proof that the Earth is not a globe.

I just watched a time lapse of the night sky that shows all the stars of heaven moving at once. This proves to me that they are something other than planets and suns far away. But I also noticed that there were really fast moving objects in the sky. Planes? meteors? I have looked up in the night sky and seen shooting stars. If its possible there is no ´´space´´, then what could they be? What are we really seeing when we look into the night sky?
Look up Admiral Byrd's tape from the 1920's (you-tube) he told us of the many continents beyond ours, all on the same plane. He said it would take years to explore them all. Then he retired from the navy and they started NASA to hide all that stuff. Yep thousands of NASA employees know the truth and are trained to keep us stupid. shows like coast to coast will never talk about the flat earth, wont even discus it, only to say NASA is correct case closed. Sounds like brain washing to me.
The flat earth movement began in the 19th century with the publications of Samuel Rowbotham. In the summer of 1838, Rowbotham conducted his Bedford level experiment. The Bedford level is a six-mile stretch of water that is very straight and level. Over the six miles, the earth ought to curve downward by 24 feet. Rowbotham stationed himself at one end of the Bedford level, and arranged for someone else in a small boat to row to the other end. A five-foot mast was attached to the boat, so certainly by the end of the level the mast would not be visible, because the top of the mast would have been 11 feet below Rowbotham’s line of sight. Rowbotham observed the boat with a telescope mounted eight inches above the water. Rowbotham could see the small boat over the entire course of the Bedford level, whereupon he became convinced that the earth was flat. I’ve previously discussed the Bedford level experiment, in which I explained that atmospheric refraction bent the light of the boat along the surface of the earth, making the boat visible, even though the boat actually was below the direct line of sight. Here I wish to expand upon the phenomenon that caused Rowbotham’s experiment to go awry.

In the next photograph and succeeding photographs, the ship is farther away, as indicated by the decreasing apparent size of the ship. In Figure 5, an inferior mirage is starting to show up. At the edge of the water, you can see a gray line, which is an inferior mirage of the row of gray containers right above the hull. On the right side of the ship, you can see the inferior mirage of the bow. The hull protrudes forward there, and the small white patch just above is a small portion of the forecastle. Notice that the inferior mirage of the bow is inverted, as one would expect. It is difficult to see here, but the lettering on the hull also is undergoing an inferior mirage too.
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.
If we move away from an elevated object on or over a plain or a prairie, the height of the object will apparently diminish as we do so. Now, that which is sufficient to produce this effect on a small scale is sufficient on a large one; and traveling away from an elevated object, no matter how far will cause the appearance in question - the lowering of the object. Our modern theoretical astronomers, however, in the case of the apparent lowering of the North Star as we travel southward, assert that it is evidence that the Earth is globular! But as it is clear that an appearance which is fully, accounted for on the basis of known facts cannot be permitted to figure as evidence in favor of that which is only a supposition, it follows that we rightfully order it to stand down, and make way for a proof that the Earth is not a globe.
Besides the above difficulties or incompatibilities, many cases are on record of the sun and moon being eclipsed when both were above the horizon. The sun, the earth, and the moon, not in a straight line, but the earth below the sun and moon–out of the reach or direction of both–and yet a lunar eclipse has occurred! Is it possible that a “shadow” of the earth could be thrown upon the moon, when sun, earth, and moon, were not in the same line? The difficulty has been met by assuming the influence of refraction, as in the following quotations:–
