I've seen stranger ideas. There's someone on BAUT (er, CosmoQuest now) who evidently thinks there's a conspiracy to cover up the invisibility of stars outside Earth's ionosphere or magnetosphere, that light only travels through vacuum as an invisible plane wave and must be converted to visible transverse waves by ions or electrical charge...apparently involving Compton shifting of x-rays somehow. All the instruments that have seen stars have secretly incorporated "gratings" (presumably diffraction gratings) to do the same thing. The close inspection the Shuttle windows get after each flight? Debris impacts are just an excuse, they're checking the gratings for damage. He thinks the Apollo landings happened, but that the star sightings were done with telescopes equipped with gratings, and that they didn't take any visible-light pictures of the stars because they wanted to hide that they weren't visible, not because they just had something rather more interesting to take pictures of. Oh, but the moon itself is visible in sunlight because of its ionosphere, or something.
He just ignores it when people point out that transverse waves go through vacuum just fine, that plane waves and transverse waves are completely different concepts that are only similar in terminology, that spacecraft regularly image stars from outside Earth's ionosphere (he insists they must have gratings or something), or that such a conspiracy would have to go back centuries and would serve no purpose whatsoever, or any of the other myriad holes in his idea.
