A prominent group of conspiracy theorists who believe that the Earth is flat will embark on a cruise to Antarctica next year to visit what they consider the ‘end of the world.’

According to the Flat Earth International Conference (FEIC), which is not associated with the Flat Earth Society, the organization will embark sometime in 2020, traveling to Antarctica by sea for its annual event.

An upcoming conference for the group will be held in Dallas, Texas in November and marks the third annual event hosted by the FEIC.
