Flat Earth: Myth debunked by Elcano in 1522

Flat Earth returns: from medieval myth to viral hoax

Flat Earth is not a revived ancient theory; it is a recent phenomenon. Until 2010 it seemed like a medieval myth, but in just a few years it moved from niche internet corners into mainstream conversation. The discussion starts with an uncomfortable thesis: according to one participant, uneducated people always believed the Earth was flat, and scholars imposed the sphere. However, chronology disproves this intuition. In 1522 Juan Sebastián Elcano settled the matter by completing the first circumnavigation of the globe and writing that they had "rounded all the roundness of the world, going west and coming back east." Antonio Pigafetta, the expedition's chronicler, also noted a one-day discrepancy in his diary upon reaching Cape Verde, practical proof that they had traveled around the entire globe.

What science already resolved

Long before, Eratosthenes measured the Earth's circumference with remarkable precision using shadows and geometry. Centuries later, Alfred Wallace, Darwin's co-discoverer of natural selection, bet a Flat Earther that he could prove the planet's sphericity. He won the bet, and the other had to pay. In short: Flat Earth does not resurrect lost ancient knowledge; it contradicts a consensus verifiable for millennia.

Why has it become popular now and not before?

Here the diagnosis fragments. One line argues that average cultural levels and IQ have been declining for years, which would explain the rise of "more primary, childish, and impossible" theories. Another points to infrastructure: previously, crazies lacked means to communicate massively among themselves, but had the need; now some have found ways to monetize that need. A third path highlights the paradoxical effect of trolling: it started as mockery of conspiracy theorists, who, more credulous than expected, took the joke as real conspiracy. The cited parallel is that of Nazbols, invented to mock people but then taken seriously by imitators.

Flat Earth as symptom, not theory

There is a more uncomfortable analysis: according to another participant, Flat Earth would be a collective visceral rebellion against science becoming less serious and more subservient to those in power. An absurd manifestation of the intuition that everything is a scam. In this reading, the Flat Earther does not reach their conclusion through observation or empirical arguments, but through a prior mental schema: if elites hide things, all official information is false. Non-roundness is not demonstrated; it is deduced from the environment. And here enters the perverse effect denounced by others in the debate: doubting the official version on any subject —for example, the Apollo program— automatically equates you with someone who believes the Earth is flat, functioning as a delegitimizing label.

The sustancia ilegal Flat Earth cannot control

Within the alternative ecosystem itself, Flat Earth is the poor relative. Even the most conspiratorial ignore it: they are pariahs within the woo world. This does not prevent it from sneaking into mass platforms with documentaries, while other uncomfortable hypotheses do not receive the same treatment. The asymmetry, they say, is not accidental.

The argument that collapses on its own

The technical defense of Flat Earth also appears, and is also dismantled. It is argued that tides cannot be gravitational because freshwater lakes barely have tides and the Mediterranean has minimal ones, while the Caspian Sea —saltwater— records between 3 and 10 centimeters. From there, it jumps to claiming seawater is diamagnetic and that the Sun, atmospheric pressure, and electromagnetic fields explain the phenomenon. The problem is quantitative: something affecting does not imply it is significant enough to explain the whole. Without numbers, the alternative hypothesis cannot bear the weight it claims.

What remains

Flat Earth grows not because of new evidence, but because the digital ecosystem rewards cheap certainty and punishes informed doubt. With these ingredients, it is predictable that the next impossible theory will arrive before we finish discussing this one. Though one should not bet too much: history shows that conspiracy fashions also fade on their own when they stop generating clicks.
