Hollow Earth Theory: Ancient Myths to Modern Science
This is where hollow Earth theory becomes not merely fanciful but genuinely useful as an interpretive framework.
The hollow Earth concept predates its modern articulations by centuries appearing in Norse mythology with the world of Svartalfheim in Celtic traditions of the underground fairy realm and in classical accounts of subterranean kingdoms.
In its more modern articulations, thinkers including Edmund Halley in 1692 proposed that the Earth contains concentric inner shells capable of supporting life lit by some interior luminescent source.
Later theorists proposed a single hollow interior with a small inner sun which would produce exactly the kind of diffuse ambient light the girl described.
