Question

Is there a dark side of the moon? (note: this question can be effectively answered either yes or no, so it is important to explain your reasoning?

Answer 1

Just as on Earth, half of the moon's surface is light and half is dark, but the area keeps changing. There's no place that's always light or always dark.

Answer 2

There is a near side and far side that are fixed because the moon is locked in its rotation with Earth. However about every month it makes a full orbit around Earth and in doing so every side is eventually exposed to the sun. Therefore there is not a permanent dark side. This means days on the moon are around 28 Earth days long.
