Atlantis and the Moon-Hoax In my work on the editorial board of a German aerospace magazine, I occasionally come into contact with supporters of conspiracy theories. In lectures about the Apollo program, at the latest, the third question from the audience is aimed at the moon conspiracy. I try to take every questioner seriously. Anyone who asks a serious question deserves a serious answer. Moon-Hoax During my last vacation on the Spanish island of  Lanzarote, I was reminded of such conspiracy theories. For various reasons I believe that there is a nucleus of truth to the myth of the island of Atlantis sunken in the Atlantic. So I know that feeling when other people look at you with pity. Many believe the Canary Islands are the remnants of Atlantis - maybe. In any case, it is a funny coincidence that my wife and I always stay here at the hotel “Atlantis”.    While walking on the beach promenade I noticed something that seemed familiar to me. In the low sun the shadows of lanterns and trees did not run parallel, instead they formed an angle. This is exactly the main argument of believers in the moon conspiracy when the shadows do not run parallel in Apollo photos. This is their proof of the fake! Probably none of the moon conspirators has gone for a walk in the evening - the shadows angles are so obvious! Flat Earth It is similar with the flat earthers. These are particularly intrusive in discussions. "Gravity doesn't exist - only the flat earth moves upwards". I always recommend to do an easy experiment: Take two fist-sized stones and drop one into soft sand from a low height and then throw the second one into the sand next to it with speed. The resulting imprints are of different depths. A higher speed therefore creates a deeper imprint.    Then they should hold a rock at knee height, one as high as possible, and drop both at the same time. Both imprints will be of slightly different depths. Then the flat earth would have to have moved up faster for one stone than for the other stone - this is not possible.    Only once did someone write to me about the result of this experiment: yes, there are two different imprints. He can't figure it out, but the flat earth theory just has to be right... ChemTrails The third aviation-related conspiracy theory is that of chemtrails. Some people think airliner vapor trails are chemicals sprayed to control their minds. Either the CIA, the Russians or aliens are responsible. When an airplane with vapor trails flies over the believers, half of them become tired and listless, the other half become hyperactive and cannot sleep. If one carefully asks why this is so, the mood of the discussion usually becomes aggressive. It is not about facts In my opinion, according to countless discussions: Conspiracy theories are not about facts. No arguments and even the simplest do-it-yourself experiments do not change the minds of conspiracy supporters. It's all about personality - everyone needs something to engage in and find like-minded people around - even if it is complete nonsense. Private opinion of Uwe W. Jack

Who believes that such shadows have never been observed by a believer in the moon conspiracy?

That is what FlatEarthers believe: The Earth is a disc with the sun, moon and stars glued onto a crystal sphere. Hard to take in the 21st century… Very funny: Some FlatEarthers were navigated to the location of my lecture using GPS.

Yes, I admit I believe in the myth of atlantis!
