Debunking Flat Earth Misconceptions
The Apollo Lunar Module needed to be as light as possible. It would also operate only in a vacuum and did not have to be sturdy or aerodynamic. To reduce weight, its hull was covered with various insulation blankets instead of rigid heat shields.
Flat-Earthers often ridicule the shape of the lunar module of being flimsy. In reality, there is no requirement to look pretty. The flimsy-looking things are just the insulation blankets. The actual hull underneath them provides structural support.
Radio waves travel at the speed of light; it takes 1¼ seconds to cover Earth-Moon distance. It is the reason in the Apollo missions after Houston says something, the response from the astronauts on the Moon will arrive only after 2½ seconds.
Some presentations of the Apollo missions are edited to cut out the gaps created by the delay, and flat-Earthers use them to dismiss the Apollo missions as fake. However, in the actual audio recordings and the transcripts, the delays are there.
Angular resolution is the minimum separation between distinguishable features in an image. Objects smaller than the angular resolution are indiscernible in the picture. The theoretical maximum angular resolution is determined by the diameter of the aperture of the optical instrument.
Flat-Earthers like to demand images of the lunar landers taken with a telescope as proof that the Apollo Moon landings did occur. In reality, no optical telescope on Earth is large enough to resolve the landers.
