Hollow Moon

The Hollow Moon theory is a hypothesis proposing that Earth's Moon is either wholly hollow or otherwise contains a substantial interior space. No scientific evidence exists to support the idea.

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:

    Ye could not know where lies a thing so fair,
    No stone is there to show, no tongue to say,
    What was; no dirge, except the hollow sea’s,
    Mourns o’er the beauty of the Cyclades.
    George Gordon Noel Byron (1788–1824)

    She is not terrified of
    begonias or telegrams but
    surely this nightgown girl,
    this awesome flyer, has not seen
    how the moon floats through her
    and in between.
    Anne Sexton (1928–1974)
