Fact Check: "The Great Wall of China is visible from space"

What We Know

The claim that the Great Wall of China is visible from space has been a popular myth for decades. However, multiple credible sources have debunked this assertion. In 2003, Chinese astronaut Yang Liwei stated that he could not see the Great Wall from space, which contradicted the long-held belief that it was visible to the naked eye from orbit (source-1). Following this, American astronaut Eugene Cernan mentioned that the wall might be visible under certain conditions, but this was later clarified by the European Space Agency, which acknowledged that the supposed image of the Great Wall was actually a river (source-1).

The Great Wall is approximately 7,300 kilometers long but is less than 6 meters wide in most places, making it extremely difficult for the human eye to discern from a distance (source-1). NASA has also confirmed that the wall is not visible from the moon and is challenging to see from Earth orbit without high-powered lenses (source-2).

Analysis

The evidence against the visibility of the Great Wall from space is robust and comes from multiple reliable sources. The physiological limitations of human vision are a significant factor; the human eye cannot resolve objects that are too small or too far away. The Great Wall's width is insufficient for visibility from space, as noted in studies of visual acuity (source-1).

Phil Plait, an astronomer, emphasizes that the resolution required to see the Great Wall is beyond what the human eye can achieve, even under optimal conditions (source-3). Additionally, the myth has been perpetuated through popular culture and misinterpretations of astronaut statements, which have been clarified by scientific explanations (source-4).

The sources used in this analysis are credible, including scientific journals, NASA, and reputable science communication platforms. They provide a clear consensus that the claim is unfounded.

Conclusion

Verdict: False
The claim that the Great Wall of China is visible from space is false. Scientific evidence and expert testimony confirm that the wall's dimensions make it impossible to see with the naked eye from space. The myth has been debunked by astronauts and corroborated by studies on human visual acuity, making it clear that this popular belief is not supported by facts.
