Introduction

At the risk of beating an already zombified horse, I thought I’d amuse myself by compiling answers to the most frequently asked questions (FAQ) and points refuted a thousand times (PRATT) posed by people in the Flat Earth discussion. The answers are from a pro-science layman. I have no official credentials, but I can read, and I can ask questions, and I can tell when something doesn’t hold together and (most importantly) I can explain why and how.

“FE” here can stand in for a hypothetical pro-Flat Earth interlocutor, someone who espouses some variety of Flat Earth as a working understanding of reality. Example:

FE: I have a question Me: here’s the answer FE: I don’t like that

So here goes!

Meta-Answer

You can substitute the following exchange for a lot of the specific answers here:

FE: how do you know that (blank)? Me: we’ve sent human beings to space FE: no we haven’t Me: what makes you doubt that? FE: it’s all fake Me: on what evidence? FE: This Looks Shopped Me: what about (grand level of effort required to pull this off)? FE: There’s a conspiracy

If this is you, congratulations, you now have to prove two things: that the Earth is flat, and that there is a conspiracy. If you try to say “there’s a conspiracy theory because the Earth is flat”, I will let you ride your merry-go-round of circular arguments on your own.

Common Tropes and Phrases

“Eight Inches Per Mile Squared”

You’ll commonly hear Flat Earthers say something about “eight inches per mile squared” as being the accepted formula for curvature. It is not.
