The hollow earth theory really quite appeals to me. I like the idea of dinosaurs, aliens, monsters, trolls and maybe a few hobbits living inside the earth. I think I have read about entrances to the inner earth through the south or maybe north pole. I heard there is an inner sun down there. I think some people have tried to argue that centrifugal force could create a hollow earth. What was that Brendan Fraser said. I need to watch that movie again
