I was aware that they were making another video about this. The hype around it and media coverage was more a bad sign than anything else, to be honest.
Anyway I have watched The Final Strawman Experiment, which, if it is actually not faked (some strange shadows and CGI glitches in there), indeed shows a constant Sun.
This, as I said earlier here, is not incompatible with a level plane and does not resolve the incoherences of the heliocentric globe model such as absence of curvature or the impossibility of gravity holding water on a ball.
The premise, which posits that showing a constant Sun in Antactica unequivocally proves the heliocentric model is real, is fallacious. Even if not fake, it debunks and/or proves nothing.
