You know they do.
They either think the final experiment was done on a sound stage with green screen, or they now think an evil government corporation made the real Antarctic sun disappear and swapped it out with a fake sun. I shit you not.
They now think while the real Antarctic sun was made hidden by means unknown, the evil corporation swapped it out with a localised plasma ball they created in the sky, by equipment unseen, and were able to make the plasma ball move at the same speed the actual sun moves at while the ball projected the same amount of sunlight and heat as the actual sun.
Luckily the plane that transported the final experiment participants to the Antarctic destination didn't collide with the plasma ball, isnt it?
It's also lucky that while filming the actual sun from south America to Antarctica on the plane flight, the evil corporation managed to do the swap and nobody noticed. They hence managed to fool Jeran, Witsit, and Isabel, along with 10 video cameras and 10 other participants over a 72 hour period and then managed to swap their fake sun for the actual sun for the return trip from Antarctica to South America and again nobody noticed the swap.
Additionally, the plasma ball created, also had spots which perfectly matched the actual sun's sun spots photographed simultaneously at other places around the world.
In other words, flat earthers refute the final experiment results and claim it was all an elaborate conspiracy hoax. A conspiracy hoax perpetrated by either all the participants including three flat earth shills, or an unknown evil corporation such as NASA, who managed to fool the entire final experiment crew and all their camera and video equipment.
Flat Earth is a conspiracy theory. So naturally anything which destroys their flat earth, is also going to be part of that conspiracy theory, albeit, another conspiracy within a conspiracy.
Ofcourse the far simpler and rational explanation, is the final experiment filmed the actual sun not setting for 24 hours, three days in a row, which utterly kills the popular flat earth rim model, dead in it's tracks. It is the final experiment, and it delivered a finality on the flat earth vs globe debate.
