बिश्वा को एउटा मात्र मानब निर्मित वाल जून चन्द्रमा बाट देखन सकीन्छा ....

A Ripley's Believe It or Not! cartoon from May 1932 claimed that the wall is "the mightiest work of man, the only one that would be visible to the human eye from the moon," and Richard Halliburton 1938 book Second Book of Marvels makes a similar claim, but it is not true. This belief has persisted, assuming urban legend status, sometimes even appearing in school textbooks. Arthur Waldron, author of The Great Wall of China: From History to Myth, has speculated that the belief might go back to the fascination with the "canals" once believed to exist on Mars. The Great Wall has a maximum width of 30 ft (9.1 m), far below the size that would be visible at a distance of 238,857 miles (384,403 km) (the average distance between the earth and the moon).
