I know, I know, this goes against everything we've ever been taught, but have you heard about the Hollow Earth Theory? I don't have very rigid beliefs about anything so I go where my research takes me and I find this theory very captivating. There is some serious scientific evidence coming through that planets are naturally hollow. Can anyone provide evidence either for or against this?Edit. Cheese: no sh** sherlock, but lava only goes a few miles down at the most and the earth is thousands of miles wide, so it would be under the lava where the earth begins to be hollow. Plus, since the inside of the earth is lava (a liquid substance) it would make sense that the earth would be hollow and here's why.. If you have a roundish-shaped object like the earth that is solid on the outside and liquid on the inside and then you rotate it at high speeds, the liquid would spread out to the inside of the sphere, therefore making it hollow.Edit2. Kurt: good evidence, but I still think it's possible that a part of the center of the earth could be hollow that your information can't "prove" otherwise, I need more solid evidence. I haven't heard of any movie coming out, I just think this theory is gaining more recognition. I read about it in a book called "The Biggest Secret" by David Icke.Edit3. Shannon, you should consider the possibility that science doesn't know everything. Just because science says something is so doesn't mean it is necessarily true. The best answer so far is from ZoidburgEdit4: Sorry coffee.. never heard of the Art Bell show. But if it talks about the Hollow Earth theory then it probably has a wider range of vision and possibilities than your ignorant narrow-mindedness
