Flat-Earthers are hilarious! I cannot believe there are still people alive who actually believe this complete and utter nonsense. Well, let's set to educating their ignorance...
The circumference of the Earth is roughly 24,901.461 miles (40,075.017 km). Round that to 25,000. Divide by 360 degrees. You get 69.44444 miles per degree.
A 25,000 mile circumference has a diameter of 7961.78 miles and a radius of 3980.89 miles. The diameter and radius are through the Earth—not around it! Anyone with half a brain cell who can do basic math knows that half the circumference is 12,500 miles, and 1/4 of that is 6,250 miles.
25,000 ÷ 360° = 69.4
12,500 ÷ 180° = 69.4
6,250 ÷ 90° = 69.4
This is what consistent mathematics looks like. These affect the surface area. Diameter and radius affect the cross section of the Earth—not the circumference!
The distance between Toronto, ON and Mooretown, ON is 140 miles.
140 miles ÷ 69.4 = 2.0173°
Follow the mathematics demonstrated here, https://www.youtube.com/watch?v=riv3x1h, and it is an approximate drop of 2.47 miles between the two points. [I have tried returning to this video with no luck. Rather than opening the link from my Facebook in its original location and then copying it, I copied it directly from my Facebook, which tends to cut off links at a certain length. The fact the video ID is only 7 characters, as well as it displaying zero info about the video or account, leads me to believe the above is the case. I have tried finding the video back with no luck. If I ever do, I will update the link as it is extremely important.]
Can you see the curve with the naked eye over 140 miles?
Flat-Earthers need a re-education in basic mathematics. Their mathematics and charts are flawed, attempting to apply a flat surface to a curved surface.
Is it not interesting that belief in a flat Earth predominantly occurs north of the Equator? Why do you suppose that is? When you look up at the night sky in Alaska, you see one set of stars, but if you look up at the night sky from the Falkland Islands, you see a different set of stars. In the northern hemisphere, when you look up at the sky in the north, you can observe stars rotate counter-clockwise around the north celestial pole, while in the southern hemisphere, when you look up at the sky to the south, you can observe stars rotate clockwise around the south celestial pole. This would be impossible with a flat Earth. The motion of stars cannot happen in a flat Earth, which is proof that the Earth is round and rotates around its axis.
Flat-Earthers are a joke. They are being intellectually dishonest, demonstrating intellectual bankruptcy, and committing intellectual suicide.
