The earth is flat not spherical

I look forward to a good one. Though it's off to a rocky start. When asking for empirical evidence, I assumed that was what was coming, however my opponents only proof is non empirical. Meaning not everyone can get in a plane and just fly in a straight line using only the senses to judge it. Pilots fly by compasses, and since the earth is a disc with magnetic north being the center, this is entirely possible on a flat earth. Flying in a giant circle is hardly noticeable, unless you were flying close to the north pole. On a globe however, the circumstances change. You would be constantly descending, nose down. This would be noticeable by passengers and pilots alike. So you must ask yourself, is it more likely that pilots are flying around a giant circle, or constantly descending? I hope this clarifies circumnavigation, which is in the FAQ I might add. This actually reminds me of a flat earth proof, which I will discuss now. 1. Flight paths Some flight paths go in very unusual directions on the globe model, but make perfect sense on what is majorly accepted as the flat earth map (of course, the map can be wrong) I use Delta airlines, as this is the most reputable, and longer lasting airline. When traveling from Argentina to Sydney, every flight makes stops in North America, which is very much out of the way. This distance, on a globe, is about the same distance as Argentina to Alaska, but the Sydney flight takes twice as long, and matches up perfectly with the flat earth map. There are many instances where flight paths exactly follow the flat earth map, and look retarded on a globe. I have found at least a half a dozen so far. This is empirical evidence of a flat earth. . http://www.debate.org... . http://www.debate.org... . http://www.debate.org... . http://www.debate.org... . http://www.debate.org... A little preface for my next proof is some information we weren't indoctrinated on: the actual curvature expected from a ball that is 25,000 miles in circumference. For some reason, we are not taught this in school. Why not? All they can say is it's so ridiculously massive, that's why there's no curve. Every high school student should be able to cite the allowed curvature over any given distance, and be able to demonstrate it in simple experimentation, but we don't, and we can't. The formula for calculating the curvature of the earth is simple. I'm sure you're going to fact check this, because everyone has to, and no one can believe it. For the first mile you should allow 8". Every mile thereafter, you will need to square the mile. So 2 miles should yield 32" of curvature. At three miles, the average human shouldn't be able to see the ground past this point. I'll let Dr Samuel Rowbotham explain it. "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, as shown in the diagram below. "Let the distance from T to figure 1 represent 1 mile, and the fall from 1 to A, 8 inches; then the fall from 2 to B will be 32 inches, and from 3 to C, 72 inches. In every mile after the first, the curvature downwards from the point T increases as the square of the distance multiplied by 8 inches. The rule, however, requires to be modified after the first thousand miles. "The following table will show at a glance the amount of curvature, in round numbers, in different distances up to 100 miles. Statute Miles Away Maths= Drop 1mile 1 x 1 x 8 =8 Inches 2 miles 2 x 2 x 8 =32 Inches 3 miles 3 x 3 x 8 / 12 =6 Feet 4 miles 4 x 4 x 8 / 12 =10 Feet 5 miles 5 x 5 x 8 / 12 =16 Feet 6 miles 6 x 6 x 8 / 12 =24 Feet 7 miles 7 x 7 x 8 / 12 =32 Feet 8 miles 8 x 8 x 8 / 12 =42 Feet 9 miles 9 x 9 x 8 / 12 =54 Feet 10 miles 10 x 10 x 8 / 12 =66 Feet "To find the curvature in any number of miles not given in the table, simply square the number, multiply that by 8, and divide by 12. The quotient is the curvation required. " As you can see, the curvature of the earth should be very noticeable, for instance, when flying from California to Hawaii, about 2,500 miles, you are flying over a 760 mile high hump of water. This math has been confirmed in cad software. Curvature can be proved wrong with simple magnification techniques like telescopes, binoculars, and the flat earther's favorite tool, the Nikon p900. 2. Distances sighted In an instance where telephoto lenses are not even necessary, a "mirage" was photographed from Michigan overlooking the Chicago skyline, a span of 60 miles, which should be 2,400 ft below the supposed curvature of the earth. When we look at the heights of the buildings in Chicago, we find that The tallest building at 1,450 ft is the Sears tower. We should not be able to see ANY of Chicago from Michigan. Now before you go agreeing with the whole bs mirage thing, think to yourself what an actual mirage looks like, usually inverted, mirrored, partially opaque, and generally distorted, Google some images of actual mirages. Conditions are perfect indeed. This is not a mirage. There are many instances of long distances being seen, and this is something that anyone can confirm, and is empirical evidence of a flat earth. . http://www.abc57.com... 3. Reflection of light on flat water Stating the obvious, the natural physics of water is to find and maintain a level surface, and has never been shown to be able to curl around a spinning ball (this "fact" is introduced young so it doesn't sound as ridiculous as it does now). Take a look at sunsets on water as the sun kisses the water, the reflection extends in a straight line, extending all the way to the viewer, or edge of the water. Warp a piece of sheet metal and hold it up to a bulb, you will never reproduce what is seen in water until you flatten the metal. This is empirical evidence of a flat earth.
