Took a few years, but Simon finally weighs in.
Lately, I’ve been discussing with a pen pal the issue of Earth’s curvature which, of course, is one of the Flat Earther’s favorite topics which they endlessly submit as ‘proof’ of the world’s flatness. Let me first make it clear that I do actually share ONE thing with the (earnest) Flat Earthers: that is, their quite reasonable request that whatever is claimed by astronomers should be EMPIRICALLY OBSERVABLE (that is, only under optical conditions that allow them to be observed).
Well we do have a bunch of controlled opposition that are positioned as Flat Earth celebrities …. but it is flat.
