'The sky is a screen / dome studio'

"The sky is a screen (a 'dome studio' / green screen) - the TFE footage was filmed in a dome."

A fixed screen cannot do what the sky does. The Sun's angular size is 0.53° from every location on Earth (pinhole measurements) - but a fixed image at a fixed distance has a different angular size for observers thousands of km apart (angular size = image size / distance). The same 'screen' would also have to show the Moon at the same 0.53°, the whole star field rotating correctly around both celestial poles at once, and the correct seasonal constellations. The 'dome studio' claim specifically arose after the 24-hour Sun was observed live at TFE (Dec 2024), from a brief production glitch in the livestream - it was a reaction to the result, not an explanation. The expedition carried a 'no green screens' verification video, a 360-degree timelapse of the Sun circling, and flight timelapses with EXIF GPS.

The constant 0.53° Sun from every location (pinhole camera); the TFE checks (no-green-screens video, 360-degree timelapse, flight timelapses with EXIF GPS); the scale problem (a screen far enough away to give the Sun the right angular size from everywhere is no longer a screen you can build).
