Flat Earth: Denialism Challenges 2,500 Years of Science
The idea that the Earth is flat is not new, but its resurgence in the digital era has peine old debates. Although sphericity was known since ancient Greece, a minority movement claims the heliocentric model is a twentieth-century orchestrated hoax. What lies behind this resistance?
Eratosthenes and Chinese Navigation Charts
As early as 240 BC, Eratosthenes calculated the Earth's circumference with minimal error. However, flat earth proponents ignore this milestone and claim that until the twentieth century, schools taught a flat Earth model. A recurring argument is that flight paths do not show curvature, when in reality pilots navigate using spherical coordinates. Chinese navigation charts, which considered the Earth's radius 2,000 years ago, contradict this narrative.
The First Circumnavigation and the RAE
The Magellan-Elcano expedition (1519-1522) empirically demonstrated roundness. Elcano wrote: "we have discovered and rounded the entire roundness of the world." Some object that "round" does not imply sphericity, but the Royal Spanish Academy defines the term as "circular or spherical." Furthermore, without Earth's rotation, currents like the Gulf Stream would not exist, and Europe would be frozen.
GPS, Antennas, and the Myth of Inaccessible Antarctica
GPS systems are based on a geoid model, not a plane. Radio link engineers use the Fresnel equation, which incorporates Earth's curvature. As for Antarctica, it is perfectly accessible: companies like White Desert offer flights to the South Pole, where the sun moves in the opposite direction to the Arctic, something impossible on a flat disk.
The Flat Earther Profile: Distrust and Conspiracy
Behind flat earth theory is systemic distrust towards institutions like NASA, accused of manipulating images. But analog photos of Earth taken before the digital era exist. The paradox is that many flat earthers use technology (GPS, satellites) that only works if the planet is spherical. The evidence is overwhelming, but faith in conspiracy persists, fueled by rhetoric equating skepticism with freedom of thought.
Meanwhile, science continues to accumulate proof: from Earth's shadow during eclipses to star observations in the southern hemisphere. The debate was never truly scientific; it is a matter of identity and narrative. And in that, flat earth theory has tough competition.
