So, mainstream scientists today believe that the Earth under our feet has a lot of molten rock and metal filling it and have gathered a lot of pretty solid evidence for it. The only complication is that we've never been able to send a human down more than several miles to actually study it up close, largely because [[No One Could Survive That]]. Which is why since times that are [[Older Than Radio]], early scientists, writers and more than a few crackpots have believed that there just might be something...or indeed, someone (say, [[Ultraterrestrials]])...down there, possibly powered by a suitably sized sun in the center.
 
The most known early example is [[Jules Verne]]'s ''[[A Journey to Thethe Center of Thethe Earth]]'', although he likely drew from theories of his time. When science started to switch over to the modern view of Earth's composition the idea of the hollow earth became a [[Discredited Trope]], but later generations of [[Speculative Fiction]] writers [[Reconstruction|took up the concept and revitalized it]]. [[Sci Fi]] works bring us hollow world concepts such as the [[Dyson Sphere]], which is a '''Hollow World''' [[Up to Eleven|taken to a solar system scale]], and other variations of [[That's No Moon|artificially constructed worlds]].
 
Note that its usual configuration, with people walking about on the inner surface, wouldn't work; a hollow sphere has ''no'' net gravitational pull on any object inside it (although some theorists, such as [[wikipedia:John Cleves Symmes, Jr|John Symmes]], claim that this actually ''could'' work due to the [[wikipedia:Centrifugal force|centrifugal force]] caused by the planet's rotation).

* ''[[Journey to Thethe CentreCenter of Thethe Earth]]'' implies that there is a second sun at the core of our own planet, meaning we live on the outside of such a sphere. At the time, before the discovery of radioactive elements, this was <s>the mainstream</s> [[Popular History|one of several speculated]] <s>scientific</s> explanations for the Earth's internal heat.
* [[Edgar Rice Burroughs]] cemented the concept in pulp with Pellucidar, an internal world where he set several of his stories, including a notable crossover with Tarzan at Earth's Core.
* ''[[Choose Your Own Adventure]]: The Underground Kingdom'', which had a star in the middle of the earth and an advanced civilization living inside of the crust.

* The Web site [http://www.psypets.net/ PsyPets] has this as part of its [[Framing Device]]; you're a volunteer working for the Hollow Earth Research Group (HERG). However, "Hollow Earth" in this setting is not ''actually'' inside Earth; rather, it's just a ''name'' given to an alternate dimension because the researchers were reminded of the old myth. References to the actual "Hollow Earth" pop up sometimes, though.
* In ''[[AH Dot Com the Series]]'', a Hollow Earth appears that combines [[Shout-Out|Shout Outs]] and [[homage]]s to just about every Hollow Earth in fiction. It first appears in "Dinos and Nazis and Deroes, Oh My!" and, {{spoiler|in a [[Tear Jerker]], is destroyed in "Harbingers"}}.
