Travel to the Earth's center

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.[1][2] Humans have drilled over 12 kilometers (7.67 miles) in the Sakhalin-I.[3]

Hollow Earth

Main article: 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 pseudoscience, the idea nevertheless remains a popular feature of many fantasy and science fiction stories and of some conspiracy theories.

In science fiction

The most famous example of a hollow-Earth fantasy is Jules Verne's 1864 science-fiction novel A Journey to the Center of the Earth.

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.

In the Teenage Mutant Ninja Turtles cartoon, the season three Technodrome is located at the Earth's core, and transport modules are used to drill up to the streets. Season three also features the episode "Turtles at the Earth's Core", with a deep underground cave where dinosaurs live, and a crystal of energy that works like the Sun to keep the dinosaurs alive. As Krang, Shredder, Bebop and Rocksteady steal the crystal to power the Technodrome, the trouble begins.[4]

Don Rosa's 1995 Uncle Scrooge story The Universal Solvent[5] imagines a way to travel to the planet's core using 1950s technology, although this would be impossible in reality. The fictional solvent referred to in the story's title has the power to condense everything except diamonds into a kind of super-dense dust. The solvent is accidentally spilled and, as it dissolves everything in its path, it bores a spherical shaft into the center of the planet. As part of a recovery effort, a makeshift platform is constructed that descends into the shaft in free fall, automatically deploying an electric motor and wheels as it approaches zero gravity, then using rocket engines to enable it to ascend again to the Earth's surface. The author Rosa describes this fantasy journey in great detail: the supposed structure of the Earth is illustrated, and the shaft is kept in a vacuum to protect against the lethal several thousand kilometers of atmosphere that it would otherwise be exposed to. The ducks must wear space suits and go without food for several days, and they are not entirely certain that the super-dense heat shield will hold. The author maintains continuity with Carl Barks, explaining that the earthquakes in the story are created by spherical Fermies and Terries.

In Tales to Astonish #2 (1959) "I Fell to the Center of the Earth", an archaeologist named Dr. Burke who is on an expedition to Asia travels to the center of the Earth (and also, as he later finds out, backwards in time)--and encounters neanderthals and dinosaurs.

In Doctor Who, a Racnoss warship is found at the center of the planet.
