Topic: Curvature

Adam Curry introduces the "Flat Earth" concept, focusing on the mathematical difficulty of explaining why lighthouses are visible beyond the calculated curvature of the Earth. John C. Dvorak dismisses the topic as nonsense, but Curry points out that NASA admits its photos of Earth are "composites" rather than single wide-angle shots. The discussion explores why these questions are gaining traction online.

Adam Curry brings up the growing online interest in Flat Earth theory, specifically questioning the mathematical calculations of the Earth's curvature and why lighthouses are visible from distances they theoretically shouldn't be. John Dvorak dismisses the topic as nonsense, while Adam questions why NASA only provides "composite" images of Earth rather than single photographs.
