Scientists have known what is contained in the Earth's core for about 75 years now, but that hasn't stopped sci-fi authors and artists from doing some wild speculation of their own.
These images by Japanese sci-fi illustrators are really far out, and I'm sure you'll agree that the Earth's core would make the awesomest setting ever for a Dungeons and Dragons campaign, or a great video game premise-Astronauts Vs. The Earths Core.
Just don't go looking for science, because these sci-fi illustrations are mostly fiction.
