Travel to the Earth's center

[3] In terms of depth below the surface, the Kola Superdeep Borehole SG-3 retains the world record at 12,262 metres (40,230 ft) in 1989 and still is the deepest artificial point on Earth.

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.

[6] Don Rosa's 1995 Uncle Scrooge story The Universal Solvent[7] imagines a way to travel to the planet's core using 1950s technology, although this would be impossible in reality.

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.
