I couldn’t help myself. Every picture I’ve been shown by Flat Earthers of the “Flat Horizon” Taken from high altitude balloons and such are quite obviously limited fields of view. This is an example of how a limited field of view on a ball can make a flat horizon.
(The little stop motion clip actually took me 4 hours to create. I used a single background photo and took pictures of the steel ball separately. I layered the steel ball over the background and the shadows of the ball are airbrushed in using a drawing app..)
