Concept
Travel to the Earth's center
Résumé
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. Planetary scientist David J. Stevenson suggested sending a probe to the core as a thought experiment. Humans have drilled over 12 kilometers (7.67 miles) in the Sakhalin-I. In terms of depth below the surface, the Kola Superdeep Borehole SG-3 retains the world record at in 1989 and still is the deepest artificial point on Earth.
Hollow Earth
The idea of a so-called "Hollow Earth", once popular in fantasy adventure literature, is that the planet Earth has a hollow interior and an inner surface habitable by human beings. Although the scientific community has made clear that this is proven false, the idea nevertheless is a less popular feature of many fantasy and science fiction stories and of some conspiracy theories.
The most famous example of Subterranean fiction is Jules Verne's 1864 science-fiction novel Journey to the Center of the Earth, which has been adapted many times as a feature film and for television. The novel is not an example of Hollow Earth, as his characters actually descend only 87 miles beneath the surface, where they find an underground sea occupying a cavern roughly the size of Europe.
The 2003 film The Core, loosely based on the novel Core, tells the story of a team that has to drill to the center of the Earth and detonate a series of nuclear explosions in order to restart the rotation of Earth's core. The drilling equipment, dubbed Virgil, includes a powerful, snake-like laser drill, a small nuclear reactor for power, a shell (of "unobtainium", a fictional material) to protect against intense heat and pressure (and generate energy to drive the engine), a powerful x-ray camera for viewing outside, and a system of impellers for movement and control. The only part of the Earth that turns out to be hollow is a gigantic geode, and soon after the drill moves through it, the hole it created fills with magma.
