Colorado pastor Will Duffy organised the highly-anticipated December 14 trip, dubbed The Final Experiment, which invited four ‘flat earthers’ and four ‘globers’ to get to the bottom of the age-old debate.

Flat earthers have long believed that Antarctica holds the key to proving that earth is, in fact, flat.

In summer, due to the tilt of the Earth, the sun does not set over much of the continent. In the flat earth view of the world, Antarctica is actually an ice wall that encircles the other continents and holds in the oceans. If that view were correct, the sun must rise and set each day, even in Antarctica, and could never circle the sky all 24 hours.

In a midnight livestream from Union Glacier Camp, Jeran Campanella from the YouTube channel Jeranism admitted to viewers, “All right, guys, sometimes you are wrong in life,”

“And I thought that there was no 24-hour sun, in fact I was pretty sure of it.”

Pastor Duffy noted Jeranism was “one of the most popular flat earth YouTube channels.”

The Antarctic trip had been in the works for three years, when Pastor Duffy learnt that there were people on Facebook who still believed that the earth was flat.

No flat earthers had ever been to Antarctica — a popular conspiracy theory was that the Antarctic Treaty of 1959 prevented them from going, as to not let them discover the truth.

In order to “end this debate, once and for all” so “no one has to waste any more time debating the shape of the earth”, Pastor Duffy arranged the $US35,000-a-head trip with Antarctic Logistics & Expeditions.

Austin Whitsitt from Witsit Gets It admitted to viewers “we were wrong” about the 24-hour sun, but said he wasn’t yet fully convinced the earth isn’t flat.

“I was one of the people that said I definitely didn’t think that there was a 24-hour sun,” Whitsitt said.

“We obviously haven’t actually seen the sun for 24 hours, but it is doing what they said it would do, very clearly. It is still dancing around high in the sky. So obviously we’re documenting it. But I said what I feel about this the whole time, truth doesn’t fear investigation. I think we’re truly trying to figure out the truth. Obviously some people think that what we were told is the truth, I don’t think that but I do think that people need to be honest and humble and be like, whoa, you know, we were wrong when we claimed that there was no 24-hour sun.”

Lisbeth Acosta from FlatEarth Gang said that what mattered most during this venture was “putting our egos aside”, to get to the bottom, or end, of the truth of earth’s surface.
