No Great Wall from Space

It’s official!  The Great Wall cannot be seen from space.  China has sent 3 astronauts into orbit and they all have said it’s not visible, but the scientists are now backing them up.  According to a local news article, scientists at the Chinese Academy of Sciences have determined that human eye can only perceive shapes up to 10 meters at a distance of 36 kilometers.  The wall is only 5 or 6 meters at it’s largest. Therefore we must conclude that it can’t be seen with the naked eye from space.  Another great myth bites the dust.

Truth be told, thanks to the smog around here, the Great Wall is often not even visible from the parking lot!
