Dark Side of the Moon
There is no dark side of the moon. All sides of the moon are illuminated at some time by the sun. This idea comes from the illusion that only the light side we see at night is the only visible one. Tidal locking is responsible for that illusion. The phase does not have anything to do with light. Tidal locking prevents us from seeing the other side of the moon, but that side still receives sunlight.
