As an artist of many years who’s work has reach some of the highest venues in the world and been applied in technology and entertainment I can tell you the cconclusions in this video are incorrect, and misleading at best. There a lot of “here’s “what happens” and not a lot of “here’s why it happens.” If you understood the why you’d then understand the conclusions drawn are incorrect based on the claimed circumstances.

I can understand this theory and the supporting visuals but an unbiased person would ask if this is possible with the traditional explanation, …and it is. We have the benefit of 3D renderings these days and can model accurate lighting and exact distances and scale. Having done an amount of this for years I can tell you with confidence this is the case. As usual the flat earthers need less disputable proof to disprove the popular belief.
