As interesting as it is that we can't see any discernible curvature at about 20 miles from the surface (in these videos), what would be the point in faking all the stuff relating to our planet and solar system, etc? There's a hell of a lot of high resolution photos and videos from an ever increasing amount of space craft, etc. I have no doubt the powers that shouldn't be hide a lot of stuff from us, but I see no logical explanation for this level of trickery. Is all this research part of a simulation theory, or what? Just examples of how strange the reality truly is?
