The claim that the Great Wall is visible from orbit survives in textbooks and trivia nights despite astronauts saying otherwise. The arguments here approach the myth from different angles: the physics of human eyesight, firsthand astronaut testimony, the role of cameras and optical aids, and why comfortable falsehoods outlive clear corrections. It becomes a lesson in how to test what everyone knows.

Open offices promised spontaneous collaboration, yet badge-tracking studies found face-to-face conversation dropping sharply once the walls came down. The findings conflict over whether open layouts inherently push people into email and chat or whether privacy fixes and design tweaks can rescue in-person teamwork. Weigh the evidence before your workplace commits to a floor plan.
