Flat-Earthers all around the globe are gearing up for their "best adventure yet." The group is organizing a cruise to the edge of the world.

The Flat Earth International Conference plans to set sail in 2020. Honestly, is it a good idea for a group of people to hop on a ship if they think it'll sail off the edge of the planet? Technically, they say that Antarctica serves as a giant ice wall, but I digress.

The largest issue they'll run into is that naval navigation disproves their theory. Ships use a system based on sailing around a globe and GPS relies on satellites orbiting Earth.
