The most known early example is [[Jules Verne]]'s ''[[A Journey to The Center of The 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 [http://en.wikipedia.org/wiki/John_Cleves_Symmes,_Jr John Symmes], claim that this actually ''could'' work due to the [http://en.wikipedia.org/wiki/Centrifugal_force centrifugal force] caused by the planet's rotation).

A related belief is that of "Concave Hollow Earth": that Earth is actually a hollow bubble inside an infinite mass of rock.

* In the semi-sequel to ''[[The Time Machine]]'', called ''The Time Ships'' (by [[Stephen Baxter]]), the time traveller returns to the future once again, but finds it changed. The Morlocks are now "good" in this future, and are also incredibly advanced, having engineered a [[Dyson Sphere|hollow sphere]] around the Sun slightly inside Earth's orbit. Morlocks live on the outside of this hollow sphere in the dark, while the Eloi live on the sunlit inside of it.
