Many modern flat-Earthers now believe that the sun sits about 3,000 miles (5,000 km) over the Earth, but Rowbotham's general idea remains popular in the community. How teeny and how close is it? According to the early flat-Earth thinker Samuel Birley Rowbotham, who published the influential treatise "Zetetic Astronomy: Earth Not a Globe" in 1881, the sun is only about 32 miles (52 km) in diameter and hovers anywhere from 400 to 700 miles (640 to 1,130 km) above the Earth, depending on the month. While you might envision the sun as an enormous ball of exploding gas located 93 million miles (150 million kilometers) away, a flat-Earther would see it as a teeny, tiny spotlight hovering just over the Earth. When they don't.fascinating disaster ensues.Many flat-Earthers agree that the sun perfectly circles the ring of the equator on the equinox however, to account for the equal hours of daytime and nighttime, the models make a few tweaks to how the sun itself looks and behaves. When 2D images overlay nicely on the 3D terrain data, these cues help everything look normal. The view is further complicated by the shadows in the aerial images, which cue our brains to look for depth. In other words, the bridge appears to follow the terrain that it actually goes over. When the flat image is projected onto this 3-dimensional surface, the bridges are projected down onto the terrain below the bridge. However, the 3D models in Google Earth contain only the information for the terrain-the landmass or the bottom of the ocean. Basically, the satellite images are flat representations in which you only see the topmost object-in this case you see the bridge, and not the landmass or water below the bridge. The images are the result of mapping a 2-dimensional image onto a 3-dimensional surface.
So what's really happening in these pictures? Here’s Valla's explanation:
