Friday 13 November 2026 has been circled in some calendars as the date humanity was supposed to end, according to a 66-year-old mathematical projection. The prediction, published in the journal Science in 1960 by Austrian-American physicist Heinz von Foerster and his team, was deliberately provocative. Titled "Doomsday: Friday, 13 November, A.D. 2026," it used historical population data to extrapolate a growth curve that would reach infinity on that date, implying that humanity would literally crush itself through overpopulation.
Von Foerster's intention was not to predict an actual apocalypse but to draw attention to the then-pressing issue of overpopulation. By choosing a Friday the 13th, he ensured the study would grab headlines—and it did. For decades, the curve matched real population figures remarkably well, but from the early 1990s onward, global population growth began to slow significantly. Today, the United Nations projects that the world's population will peak at around 10.3 billion in the mid-2080s, then gradually decline.
Why the prediction failed
The core flaw in von Foerster's model was the assumption that past trends would continue unchanged. As the study itself noted, people adapt. The rapid population growth of the mid-20th century was driven by falling death rates, but birth rates soon followed suit. By 2020, annual growth had fallen below one percent, down from a peak of over two percent in 1963.
This pattern is visible across Europe, where several countries, including Italy, Germany, and Poland, are already experiencing natural population decline. The continent's demographic challenges are a stark contrast to the Malthusian fears of the 1960s. Rather than facing a population explosion, many European nations are grappling with aging populations and labor shortages.
Friday's non-event is not the first time a predicted end of the world has fizzled. In 1910, panic over Halley's Comet led to sales of gas masks and "comet umbrellas" as newspapers warned of poisonous gases in its tail. In 2011, a US radio preacher predicted Judgement Day on 21 May, and in 2012, the end of the Mayan calendar sparked similar fears. Even scientific studies have erred: the 1972 Limits to Growth report warned of imminent resource depletion, but innovation and new discoveries have kept many commodities affordable.
The lesson, as von Foerster himself might have appreciated, is that humanity is not passive. We respond to challenges, adapt our behavior, and find solutions. The doomsday clock may have been set for 13 November 2026, but it has been reset by the very human capacity for change.
For those still worried, rest assured: the only thing happening this Friday is the usual run-up to the weekend. And if you're planning travel, note that Naples airport will close for a runway overhaul later this month, a more concrete disruption than any apocalypse.
In the meantime, Europe continues to face real challenges—from demographic shifts to environmental concerns. A recent German military study highlighted persistent issues of sexual misconduct, while wind turbines kill millions of bats annually, a reminder that even green energy has trade-offs. These are the issues that deserve our attention, not a 66-year-old mathematical curiosity.
So, as Friday 13 November 2026 dawns, the world will wake up as usual. The doomsday prediction will join the ranks of other failed prophecies, a fascinating footnote in the history of science. But it also serves as a reminder: the future is not set in stone, and our choices today shape the world of tomorrow.
