The Great Wall of China
Having done little research into the way the human eye perceives the light that bombards it, I was left rather stumped by a question posed earlier in the day.
Why is the Wall of China the only man-made construction visible from space* when other constructs with a presumably greater width (perhaps the Millenium Dome? There are better examples I'm sure) are not?
Thanks for helping me help you to waste our time. It's been an experience.
*I apologise if this is a myth.
