Is there even proof of this? Surely not.

I mean, I'm not very knowledgeable when talking about the earth, and what its made of but simple physics would tell you that this is quite impossible. If ever the earth was really hollow, the weight of everything above it would just crush whatever is in the "hollow earth" due to the weight.

I really like reading conspiracy theories to be honest, but this is just as rediculous as the "earth is flat" theory. Completely nuts.
