Everyone knows that the Earth is a sphere, right? Not so fast! There is a small, but vocal, group of people out there that believe the Earth is flat. Yup... fall off the edge flat. But don't worry, there is a big ice wall circa Game of Thrones holding in our oceans and keeping us safe.

We're walking you through exactly what the flat Earthers believe to be the truth, how NASA is guarding the wall, the reasons gravity doesn't exist and so much more! Who knows? Maybe you'll become a true believer after this.
