The moon doesn't rotate, so no night or day.
Of course the moon rotates. Once a month.
The dark side of the moon is a music album, not any description of reality.
Which was what I meant to convey, but stuffed it up.
I was thinking about how the moon presents the same side to us, & that there was always some part of the moon lit by the sun.
I neglected the fact that we don't see
all of the same side, all of the time.
