BTW
The moon doesn't have a 'dark' side as such it's just that we don't see that side.
That's a belief rather than a statement of fact
Depends on your definition of 'dark'.
Albedo is a measure of reflectivity: 0 is perfectly black; 1 is perfectly reflective.
The Moon has an albedo of 0.136, which is very close to that of worn asphalt @ 0.12 (source: Wikipedia).
