Flat Earth Theory
Flat Earth Theory is the online-driven claim that the planet is a flat disc rather than a sphere, revived by a 2004 web forum and pushed into mainstream culture by celebrity converts and the 2019 Netflix documentary Behind the Curve.
Overview
Flat Earth Theory is the belief that the planet is a flat disc rather than a sphere, kept alive by a small but loud subculture of online forums, YouTubers and celebrity converts1. Adherents typically argue that space photography is faked, that Antarctica is a giant ice wall ringing the disc, and that the sun and moon rotate above our heads inside a dome1.
The modern scene sits somewhere between sincere conspiracy belief and internet trolling, with Facebook groups, Twitter accounts and YouTube channels pulling in tens of thousands of followers3. Psychologists writing about the movement describe it as a symptom of wider distrust in institutions and the way the web gives safe harbor to fringe ideas2.
How It Spread
How to Use This Meme
Rather than a template, Flat Earth Theory functions as online shorthand, invoked to mock conspiratorial reasoning or to ironically "prove" absurd claims. Posts often pair a stretched physics diagram with a straight-faced caption, or riff on the ice wall and dome cosmology described in Behind the Curve1.
