Flat Earth Theory

Of all the conspiracy theories that litter the Internet, the flat Earth conspiracy is quite possibly the most curious. After all, the ancient Greeks figured out the planet's shape (and even its circumference) in the third century B.C. 

But a fringe society founded in the 1950s, dedicated to insisting that the Earth is flat, has given rise to a modern ground of flat Earth adherents. These believers claim that the Earth is a flat disc, and that evidence that it is round — say, pictures taken from space — are an elaborate hoax involving multiple governments. Opinions differ on exactly how the flat Earth works, with believers concocting elaborate versions of physics and creative interpretations of the solar system to make their theories work.
