Years ago I somehow wound up engaging a Lunar Landing Denialist–you know, one of those strange folks who insisted that there was no way anyone actually went to the moon, the whole thing was faked, it was a soundstage, yada yada yada. I tend to have zero patience for such nonsense and I shut it down pretty much as soon as the question “If we were there, why doesn’t the Hubble Space Telescope take pictures of the landing site!” came up. I might have provided a link to someplace somewhere explaining why that’s not possible, but I don’t remember.
Luckily, though, Randall Munroe of xkcd is on the job!
