I was just perusing the welcome thread, and I noticed Dubay actually signed up here in December 2013, @ericdubay (he just made that one post, and never returned). On his blog the oldest post tagged with Flat Earth is also in Nov 2014, coinciding with the http://www.atlanteanconspiracy.com/2014/11/the-flat-earth-conspiracy.html Before that he had a passing familiarity with the topic, and willing to consider it. Aug 2009: http://www.atlanteanconspiracy.com/2009/08/alex-jones-mentions-atlantean.html Later he rejects the Heliocentric model of the solar system in favor of the geocentric, but does not explicitly say the earth is flat: Nov 2011 In the comments on that post, a year later (Aug 2012), he's getting closer to Flat Eartherism. http://www.atlanteanconspiracy.com/...howComment=1344999183588#c2621435188679110855 The links he gives there are to the 1881 book "Zetetic Astronomy", a section on perspective that seems to have been written by someone with poor eyesight who is unfamiliar with telescopes. The argument there is that a "hull down" ship does not have the hull below the horizon, but instead just has the hull too small to see, because as it's smaller than the sails, it vanishes first because of perspective. It's interesting that Dubay presents this obviously wrong explanation as a good challenge. But it seems like at some point after 2012 he decided to go entirely flat-earth, presumably he felt it fit well with his large scale, long term, "Atlantean" conspiracy. Here's a recent video he made, adding illustrations to a radio interview he gave: It seems at first like an endless stream of trolling, correction-bait, but then it seems like he really does believe it. His book contains things that are inarguably false: https://books.google.com/books?id=effuBwAAQBAJ&pg=PA135&lpg=PA135&dq="eric+dubay"+"hull+down"&source=bl&ots=0hh2zPclum&sig=_XRBVAQgIQA6NXIx2fh3xpxZ4uo&hl=en&sa=X&ved=0ahUKEwjqltO9gtfKAhUT9GMKHSV9C1MQ6AEIMjAE#v=onepage&q="eric dubay" "hull down"&f=false Could it be that all the Flat Earthers share this misunderstanding of perspective? There's a real dissonance here, because clearly there are multiple examples of the bottoms of ships NOT "zooming into view" when viewed through a telescope. This is particularly clear with large liners, such as in the comic on the right above. An excellent example is in this album: https://www.facebook.com/dave.greg1...92969940750.1073741918.100002201677137&type=3 Looking through a telescope (a zoom lens) on the left, half the ship is still below the horizon. It would seem that presenting evidence such as this should be undeniable evidence that the earth is not flat. Do people reject this? Are they simply unaware of this? Does this evidence just need publicizing more? Is it worth pointing out just how incredibly wrong Dubay is on this point? I'd certainly not want to waste time debunking every single point in his book - but I'd really like to hear how he explains these telescopic photos of ships that directly violate what he claims in his book.
