Debunking Flat Earth Misconceptions
The Hafele–Keating experiment was a test of time dilation. Four atomic clocks were flown around Earth, following and against Earth’s rotation, then compared to those remaining on the ground. The results were consistent with relativity.
The theory of relativity can be counterintuitive & difficult to understand. The Hafele–Keating experiment demonstrates a direct measurement of time dilation, a specific aspect of relativity, using a practical concept in our everyday lives.
In cinema, a making-of or behind-the-scenes is a documentary featuring the production of a film. It describes how the scenes in a movie were created. Some trolls took footage from the behind-the-scenes of various space movies and present them to flat-Earthers as though it is how space agencies “faked” their videos.
Flat-Earthers fail to realize that these footage were just behind-the-scenes of space movies and unrelated to the actual space footage from space agencies. These spread as hoaxes in flat-Earth circles.
