There are also anomalies at large scale geometry caused by the laws of physics described by General Relativity.
Like, for example, the Earth is more flat to the ISS than to a geostationary satellite. This is not semantics, it is **literally** flat if you orbit it fast and close enough.
Most physicists don't understand these nuances and questions, and that contributes to the entrenchment.
In my opinion Flat Earth is a well orchestrated psychological operation, that includes brilliant brainwashing techniques, to keep people away from the idea of space colonization. For reasons.
