Rant: I spent two years arguing about flat earth until a guy in a Denver coffee shop asked me one simple question
I was deep into all the usual arguments, you know, the curvature stuff, the NASA lies. This older guy at the next table overheard me and just asked, 'If it's all fake, why do cargo ships disappear hull-first over the horizon?' I tried to explain it with perspective, but he pulled out his phone and showed me a video he took from a beach in Maine last summer. You could literally watch a tanker sink bottom-up until it was gone. My whole spiel just fell apart right there. Has anyone else had a basic, real-world observation completely dismantle a theory they were defending?
