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:
“Since ever they flung abroad in spring
The leaves had promised themselves this flight,
Who now would fain seek sheltering wall,
Or thicket, or hollow place for the night.”
—Robert Frost (1874–1963)
“I do not believe in erecting statues to those who still live in our hearts, whose bones have not yet crumbled in the earth around us, but I would rather see the statue of Captain Brown in the Massachusetts State-House yard than that of any other man whom I know. I rejoice that I live in this age, that I am his contemporary.”
—Henry David Thoreau (1817–1862)
