Flat Earth Self-Debunk: Danyang–Kunshan Grand Bridge meme shows Hangzhou Bay Bridge
Deconstructed - Auguste Piccard: “It seemed a flat disk with upturned edge”
Deconstructed - Auguste Piccard: “It seemed a flat disk with upturned edge” Is it possible he means it looked like an upturned disk? As in, you see a bit of horizon curvature? Stratobowl image from 1935 The human eye has a wide field of view so you see a bit more of the Horizon Circle than most images and thus more curvature, all else being equal. One reason for this is that this is NOT the "curvature of the Earth" -- this is the curvature of the Horizon Sagitta viewed nearly on edge . This is a mistake I constantly see people making. So it's not a circle of 3959 miles diameter that curved downward, but an OVAL that you are in the middle of with, in this case, a 300 mile radius and viewed on edge at a 4.8° angle -- and this oval curves 360° around YOU. As to why it looks flat, it's because the terrain is far away and the curvature is fairly slight and you're looking down on it. We just cannot see the geometry under these conditions. You can't even see the...
