Context_2 : The Hollow Earth is a pseudoscience concept proposing that the planet Earth either is entirely hollow or otherwise contains a substantial interior space. The scientific community has dismissed the notion since at least the late 18th century. The concept of a hollow Earth recurs many times in folklore and as the premise for subterranean fiction, and a subgenre of adventure fiction ("Journey to the Center of the Earth", "At the Earth's Core"). It is also featured in some present-day pseudoscientific and conspiracy theories. Context_3 : Cyrus Reed Teed (October 18, 1839 December 22, 1908) was a U.S. eclectic physician and alchemist turned religious leader and messiah. In 1869, claiming divine inspiration, Dr. Teed took on the name Koresh and proposed a new set of scientific and religious ideas he called Koreshanity, including a unique Hollow Earth theory that posits the Earth and sky exist inside the inner surface of a sphere. Context_4 : Subterranean fiction is a subgenre of adventure fiction or science fiction which focuses on underground settings, sometimes at the center of the Earth or otherwise deep below the surface. The genre is based on and has in turn influenced the Hollow Earth theory. Context_5 : Travelling to the Earth's center is a popular theme in science fiction. Some subterranean fiction involves traveling to the Earth's center and finding either a Hollow Earth or Earth's molten core. Context_6 : Before the concept of plate tectonics, global cooling was a geophysical theory by James Dwight Dana, also referred to as the contracting earth theory. It suggested that the Earth had been in a molten state, and features such as mountains formed as it cooled and shrank. As the interior of the Earth cooled and shrank, the rigid crust would have to shrink and crumple. The crumpling could produce features such as mountain ranges.
