As mind-boggling as it sounds, there are people out there who think the earth is flat. They are convinced that the planet is not a globe, but a disk, with an edge that is an ice wall. This ice wall is supposed to be Antarctica and what lies beyond it is apparently a great mystery that flat-earthers cannot wait to decipher.

To prove this theory, the Flat Earth International Conference is organizing a Flat Earth Cruise to the “edge of the world,” i.e. the seventh continent, in 2020. Very few details have been released about the voyage as of yet, but FEIC promotes the event as the “biggest, boldest, best adventure yet.”

“Beyond the ice wall is a topic of great interest to the Flat Earth Society,” it says on its website. “To our knowledge, no one has been very far past the ice wall and returned to tell the journey.”

While it’s certainly an appealing sales pitch for deluded adventurers, we’re hoping the trip will be eye-opening — but there’s no telling with flat-earthers.

More details about this cruise will likely be revealed at the Flat Earth International Conference in November, in Dallas. But if looking for the nonexistent “edge of the earth” isn’t really your thing, or if you’ve actually listened in school, there are plenty of non-conspiracy based, cool cruises out there, including to Antarctica.
