It's a common misconception that the Great Wall of China is visible from space with the naked eye. While it's a massive structure, its width is relatively small compared to the vastness of space.
Here's a breakdown of why it's difficult to see:
Width: The Great Wall is not uniformly wide. While some sections are wider, many parts are quite narrow, making them difficult to distinguish from the ground below, especially from the vastness of space.
Color: The wall's color blends in with the surrounding landscape, further hindering its visibility from orbit.
Distance: Even from low Earth orbit, the distance is significant enough to make it challenging to discern such a narrow structure.
While it's not visible to the naked eye, high-resolution satellite images can capture the wall due to their advanced imaging capabilities.
It's a fascinating topic that highlights the limitations of human perception when compared to the scale of the universe.
