The concept is related to or derived from the better-known Hollow Earth theory, and was an infrequent but recurring plot device in pre-spaceflight science fiction.

Famous quotes containing the words hollow and/or moon:
“She could give herself up to the written word as naturally as a good dancer to music or a fine swimmer to water. The only difficulty was that after finishing the last sentence she was left with a feeling at once hollow and uncomfortably full. Exactly like indigestion.”
—Jean Rhys (1894–1979)
“When we choose to be parents, we accept another human being as part of ourselves, and a large part of our emotional selves will stay with that person as long as we live. From that time on, there will be another person on this earth whose orbit around us will affect us as surely as the moon affects the tides, and affect us in some ways more deeply than anyone else can. Our children are extensions of ourselves in ways our parents are not, nor our brothers and sisters, nor our spouses.”
—Fred Rogers (20th century)
