👇 Here's what a result looks like
Claim checked
"The Great Wall of China is visible from space with the naked eye."
❌ FALSE
What the evidence shows
This is a widely repeated myth. The Great Wall is only about 15–30 feet wide — far too narrow to be seen from space without aid. NASA astronauts and Chinese astronaut Yang Liwei have confirmed they could not see it from orbit.
🧠 Why this matters
This claim has been repeated in textbooks for decades — a reminder that even "established facts" can be wrong, and that popular repetition is not the same as evidence.
📚 Where this comes from
NASA, Snopes, and statements from multiple astronauts including Yang Liwei (China's first astronaut) all confirm this claim is false.
