Hollow be thy Earth

Happy Earth Day everyone, with this holiday comes Earth based fringe topics. We bring you, Hollow Earth. We start with the history of this theory going back to antiquity times (where the best antiques come from!) then we look at the modern iterations of this strange phenomenon up to and including vacation itineraries. We finish off by looking at offshoots of this topic, like maybe we are the interior of the Earth!!In the intro we learned that the machines are coming for the good jobs, like alien hunting. What will be left for us common folk? :(
