Earth: Spherical vs Flat

RebuttalsThe "mirage"The photo taken from Mr. Nowicki's profile and used on my opponent's source is not a photo of the mirage: it is a photo taken from atop Warren Dunes State Park, a park built around a dune that rises 260 feet over the lake, fifty miles from Chicago according to Nowicki's description of the photo. Mr. Nowicki's profile also does contain pictures of the mirage, but, as you should see, the mirage is appropriately upside down and disfigured. I'll elaborate more on seeing things from long distances in my next arguments.GyroscopesGravity. Gravity explains how gyroscopes work. Gravity pulls the gyroscope towards the center of the Earth, which appears to stay the same for the same reason that nothing is seemingly affected by the Earth's many movements: frame of motion. Everything within the atmosphere of Earth is wobbling, spinning and rotating around the sun together: this gives the impression that nothing is moving at all. It is the same reason that you can sit in the back of a car going sixty mph, throw a ball ten mph to the front of the car, and that ball will technically be moving at seventy mph, but, to the people in the car, the ball will appear to be going ten mph, because everything inside the car is going at least sixty mph.The HorizonThe Earth has a circumference of almost 25,000 miles. One must be completely out of the atmosphere of the Earth in order for them to see the curvature of it, and it will still be rather difficult to see despite that, in short, you have to be very, very far from the surface. If one stands upon Earth, and looks 360 degrees around him, he is going to see an equal distance from around him (unless, of course, there are obstructions in his way) and therefore, the horizon will appear to be a circle and two-dimensional. Of course, there is eyewitness and photographic evidence from outside Earth's atmosphere demonstrating it's curvature, but, conveniently enough, it is all part of a conspiracy to keep us all believing the Earth is round for... reasons. Fish-eye lenses are well-known to be used by NASA and similar organizations; there aren't many people who can't look at a fish-eye lens and realize they are looking through a fish-eye lens. They are used to spare some visual accuracy for a broader view of what's happening.The Sun is CloseI would like to know how my opponent got the numbers for his trigonometry, because it both has to rely on supposing the Earth is flat but also the angles are accurte. The distance of the moon is over 238,000 miles away. This is known most basically because of the use of radar and lasers. If you don't know how radar works, I'll put a link to a short explanation in the sources. Also, the distance to the sun can be calculated through trigonometry using venus as a second point instead of two places on Earth and get much closer to the actual distance from the Sun to Earth of more than 92 million miles.(1)I would spend more time explaining these processes myself, but I'm afraid that, to my opponent, everything is a conspiracy, so I will be wasting my time. Instead, I encourage everyone to read Cornell's explanation, as it would be better than mine anyway,More ArgumentsTwenty-four hour daysDuring the summer months in Anarctica, the sun never sets and allows for twenty-four hour day. This is impossible on the flat Earth model, as Anarctica stretches around the circumfrence of the Earth, and is only possible on the round Earth model.(2) A time-lapse video can be found here: ;Mount ChimborazoMount Chimborazo is the highest point on planet Earth: the furthest ground from the center of the planet. If the Earth is flat, one with a modern telescope should be able to, with no problem, pear from atop Mt. Chimorazo in Ecuador to the other side of the world at Mt. Everest. Of course, this is not proven as no one has tried such a thing because no one has felt great need to prove the Earth is round for over 2000 years. Regardless, the same principle is applicable in other scenarios. Such as in the Chicago-Michigan delima. If the Earth is flat and water sits level, which it does, then one standing on the opposite shore in Michigan should be able to see Chicago every day, but they cannot. I should be able to stand on the Outer Banks in North Carolina with a telescope and see over the Atlantic ocean to Morocco. Never mind the tides because...Gravity and TidesGravity does not exist on a flat Earth like it does on a round Earth. Gravity is a force that attracts massive objects to massive objects. The gravity of the moon is what pulls on the great bodies of water of Earth, causing tide. But the effect of gravity, as explained by all flat Earth models I've seen, is caused by a steady upward force of the Earth, pushing everything upon it down: this does not account for tides. Lunar EclipsesIn the lunar eclipse, on the round Earth model, the moon is on exactly the opposite side of the Earth from the sun and, because of that, looms in the Earth's shadow perfectly. We can see the Earth's round shape as the lunar eclipse sets. Yet again, any of this phenomina is impossible on a flat Earth model.Star ConstellationsFirst observed by Aristotle, when he noticed that there seem to be different stars in the sky at Cyprus and Egypt where he had went on a trip. This is because the latiudinal curvature of the Earth blocks out our view of star and star constellatons at different latitudes as illustrated with this image:http://www.debate.org...This is impossible on a flat Earth because you would be able to see all or at least more constellations on your respective longitudinal position, such as in this image:http://www.debate.org...The View of the MoonThe view of the moon is introverted between the Northern and Southern hemispheres, as seen here:http://guanolad.com...This is impossible on a flat Earth model.Source(s)Warren Dunes State Park http://www.michigan.org...;How radar works: http://starchild.gsfc.nasa.gov...(1): http://curious.astro.cornell.edu...(2): http://petapixel.com...
