These Flat Earthers say they're interested in "Ptolemaic science"? That's the funniest thing I've ever heard! Ptolemy's geocentric thesis assumes the Earth is ROUND. Have these goofballs -- oops, I mean goofplanes -- ever heard of the "music of the spheres"?
Also,
All these Flat-Earther, geocentric, and anti-evolution types are using modern technology to spread their message. But they all share a distrust, in some form or another, of modern science. It never dawns on them how that technology they love so much came to be. The very foundation of modern technology is the scientific method, which leads to theory, which leads to basic research, which leads to applied research -- and that led to newfangled tomfoolery such as electrical generation, transistors, digital computers, integrated circuits, packet switching, the Internet, GoFundMe, YouTube, e-mail, cell phones.
That's the dilemma that always confounds me. These people reject basic science that the technology they love depended on.
