I can’t imagine how the shape of our planet can be used to control us. I mean, if the earth was neither round nor flat, but… I don’t know, toroidal. How would that affect our behavior?
Is non-Euclidean geometry more likely to make the population docile?
And why not use the flat earth as a form of control? Since that vision is much more limited than the traditional one, since there is no space, no gravity, no planets, no stars and no cosmos. Just what you can see and nothing more.
