"200 Proofs Earth is Not a Spinning Ball" by Eric Dubay is a 2014 book outlining arguments for a flat Earth, challenging the heliocentric model. It posits that the Earth is a stationary, flat plane, relying on sensory perception, claims about the lack of curvature, and conspiracies regarding NASA and scientific consensus. It rejects gravity and orbiting. The book serves as a cornerstone of modern flat Earth theory, promoting a "zetetic" approach that favors sensory observation over established scientific theory.
