A scientific theory published 66 years ago has resurfaced on social media, reigniting claims about the “end of the world” on November 13, 2026. In fact, the study in question did not speak of the physical extinction of humanity, but of the limits of uncontrolled growth in the world population.

From a Science article to a viral alarm
The theory was published in November 1960 in the scientific journal Science by physicist and cyberneticist Heinz von Foerster, together with researchers Patricia Mora and Lawrence Amiot of the University of Illinois.
In the article titled “Doomsday: Friday, 13 November, A.D. 2026”, the authors analyzed historical world population data from 400 BC to 1958. That dramatic title is precisely one of the reasons the study continues to be recycled as sensational news even today.
What the model actually predicted
According to the researchers’ calculations, Earth’s population was growing at an ever-faster pace. If that trend had continued uninterrupted, the mathematical model led to a point called a singularity on November 13, 2026, where the number of inhabitants would theoretically become infinite.
This did not mean an apocalypse in the popular sense of the word, but rather an absurd mathematical limit signaling the impossibility of indefinitely continuing the same demographic trajectory, given the limits of space and natural resources.
Why the date November 13, 2026 was chosen
The date was not chosen at random. November 13 was Heinz von Foerster’s birthday, and the authors noted that in 2026 it would fall on a Friday, creating the symbolic combination of “Friday the 13th,” associated with bad luck in Anglo-Saxon culture.
So the choice of the date itself also carried a symbolic and provocative element, beyond the statistical calculations presented in the study.
Why the prediction did not hold
Over the decades, demographic developments overtook that model. Since the 1970s, the pace of world population growth has begun to slow significantly, while in many countries declining birth rates have been observed.
According to United Nations projections, the world population is currently estimated at around 8.2 billion and is expected to continue growing for several more decades, reaching a peak of about 10.3 billion in the mid-2080s before a gradual decline. This makes it clear that November 13, 2026 is not the date of any predicted end of humanity.
What remains of the debate today
Although the 1960 model proved wrong within the timeframe it suggested, the question it raised remains open: how can the balance between population growth, natural resources, and the planet’s sustainability be maintained?
The case also shows how a mathematical model, detached from social and economic changes, can produce striking conclusions that are later recycled out of context as a “prophecy.”
At its core, the study was not an announcement of the end of the world, but a warning about the limits of endless growth. The viral alarm circulating today relies more on the title and the symbolism of the date than on the actual content of the research.
That makes the story less mystical and more of a classic example of how public fear can be fueled by partial readings outside the scientific context.
