Flat Earth

Since my opponent has already familiarized himself with my debates and has an expected and accepted disadvantage (this is all i debate about), I'll just recycle and argument or two, and add as I see fit in round one.Contention One: GyroscopesDefinition from Wikipedia: A gyroscope, not to be confused with gyrocompass, is a spinning wheel mounted on a gimbal so that the wheel's axis is free to orient itself in any way. When it is spun up to speed with its axis pointing in some direction, due to the law of conservation of angular momentum, such a wheel will normally maintain its original orientation to a fixed point in outer space (not to a fixed point on Earth). Since our planet rotates, it appears to a stationary observer on Earth that a gyroscope's axis is completing a full rotation once every 24 hours. (1) Anyone who has ever owned a gyroscope can verify that they do verify that they do very curious things, even seemingly defying "gravity" sometimes. This experiment show both that the earth is NOT rotating, and can't be a ball. Gyroscopes have been spun up for hours at a time, and not even the slightest of rotations can be observed. (2) Attitude indicators operate by use of a basic gyroscope. (3) If the earth were a ball, spinning, wobbling, going around the sun, which is bolting around our galaxy, that is rocketing around the universe at a combined rate of about 1,000 miles per second, they would be virtually useless, especially on transcontinental flights. Some higher end smart phones are equipped with a built in gyroscope. If yours has one, download any decent pitch indicator, and leave it on your night stand when you go to bed. Wake up in the morning and see for yourself that the phone has not moved or changed it's angle the entire time. Since your average person can get a good gyro and produce these same results, this is another (objective) empirically experimental proof that the earth is flat, and it isn't spinning. Contention two: No CurvaturePreface: Why were we never taught the curvature of the earth? We see the flatness everywhere. Go to the beach, look to the horizon, flat. They tell you it's because of the earth's monstrous size that we can't see any curvature, often using comparisons like a germ on a bowling ball. But what they don't tell you is that the curvature of a ball that is 25,000 miles in circumference SHOULD in fact have a very noticeable curve. As I'm sure you have or will do now, a Google search provides a reasonably small amount of curvature for a mile, but further investigation provides a diagram not unlike the one below. The second mile will square, and will square every mile thereafter. So, the ground or sea 2 miles away will be 32" downhill from you. At 3 miles, a full six feet of curvature would hide another human. This formula is actually quite accurate and easy to use, first discovered by a flat earther in the 1800's. From Dr. Samuel Rowbotham: IF the earth is a globe, and is 25,000 English statute miles in circumference, the surface of all standing water must have a certain degree of convexity--every part must be an arc of a circle. From the summit of any such arc there will exist a curvature or declination of 8 inches in the first statute mile. In the second mile the fall will be 32 inches; in the third mile, 72 inches, or 6 feet,(square the mile) as shown in the following diagram: The formula for calculating how much curvature is M^2X8=the amount of curvature in inches, where M is the mileage. Joshua Nowicki has been photographing the Chicago skyline for a few years now. As the crow files, this is 57 miles, which should yield 2,166 feet of drop. (57X57X8/12=2,166') This would be impossible if he were doing so on a ball that is 25,000 miles in circumference. (4) Modern science tells us that this is a mirage, but again, anyone who's actually seen a mirage, superior or otherwise, will agree that mirages are just "reflections" most of the time they are greatly distorted, and always upside down. Granted, visibility factors such as atmospheric blocking and waves and swells on lake Michigan sometimes do not grant this sight always, but the skyline is seen on a regular basis. (5,6,7) This isn't the only instance of people being able to see further than they should, in fact, people are recently testing the globe, and the flatness of water to see landmarks that should be well over the curvature of the earth, and every time this test is done, no curvature can be found. This can be done easily if there is a fairly large body of water near you. All you need is a decent camera and the earth curvature calculator(8). This is yet another (objective) empirical proof that the earth is flat. Contention three: The radio broadcast of 1915 (9) The radio broadcast of 1915 would be impossible on a globe. Having no relay towers then, and seeing how radio waves do not travel in curved lines around a ball, my opponent must explain how this is possible. At 3,800 miles, there should be a 1,823.232 mile hump of water between the two, not to mention the distance to Honolulu.
