The Hollow Earth hypothesis proposes that the planet Earth is either entirely hollow or otherwise contains a substantial interior space. The hypothesis has been shown to be wrong by observational evidence, as well as by the modern understanding of planet formation; the scientific community has dismissed the notion since at least the late 18th century.
The concept of a hollow Earth still recurs in folklore and as the premise for subterranean fiction, a subgenre of adventure fiction. It is also featured in some present-day pseudoscientific and conspiracy theories.

Famous quotes containing the words hollow and/or earth:
“To be shelterless and alone in the open country, hearing the wind moan and watching for day through the whole long weary night; to listen to the falling rain, and crouch for warmth beneath the lee of some old barn or rick, or in the hollow of a tree; are dismal things—but not so dismal as the wandering up and down where shelter is, and beds and sleepers are by thousands; a houseless rejected creature.”
—Charles Dickens (1812–1870)
“The earth yields up her stores, of every ill
The instigators; iron, foe to man,
And gold, than iron deadlier.”
—Ovid (Publius Ovidius Naso)
