Empirical Earth · The Boomerangs — Flat-Earth Proofs That Backfire
The claim
“You can’t even get to Antarctica, and the 24-hour Sun there is faked.”
What is true
Both camps had agreed beforehand that observing the Sun continuously for 24 hours there would refute a flat Earth, and Duffy pledged to concede a flat Earth if the Sun set.
What is measured
Both sides agreed in advance that a continuous 24-hour Antarctic Sun would refute a flat Earth. In December 2024 eight people watched it happen, and the flat-Earthers among them said so on camera.
What would show this is wrong
the Sun setting at Union Glacier during the southern summer, or any independent traveler reaching the Antarctic interior in December and filming a normal sunrise-and-sunset cycle.
