If you woke up this morning, Friday, 13 November 2026, you have already outlived one of the most famous predictions in the history of science. More than six decades ago, three researchers at the University of Illinois calculated that this very date would mark “doomsday” for humanity. The date has arrived, the world is still turning, and the story behind the forecast has gone viral this week.
The prediction was never about asteroids, wars or a religious end of days. It was a mathematical warning about population growth, and understanding why it failed tells us a great deal about how the world, including fast-growing countries like Nigeria, has changed since 1960.
Where the “Doomsday” Date Came From
In November 1960, physicist Heinz von Foerster and two colleagues, Patricia Mora and Lawrence Amiot, published a paper in the respected journal Science under the provocative title “Doomsday: Friday, 13 November, A.D. 2026”. According to Euronews, the team analysed estimates of world population stretching back about 2,000 years and fitted a growth curve to the figures.
What they noticed was that the time it took for humanity to double in number had been getting steadily shorter. When they extended that trend into the future, their equation showed the number of people shooting towards infinity in late 2026, which they pinned to this Friday. Swiss outlet Bluewin noted that the calculation actually gave a range of years rather than a single day, and the authors chose the dramatic date partly to grab attention.
Why the Prediction Did Not Come True
The model assumed that the speed-up in population growth seen up to 1958 would simply continue. It did not. Global population growth peaked in the 1960s and has slowed ever since, as death rates fell, education spread, more women entered the workforce and families in most regions chose to have fewer children.
Today there are roughly 8.3 billion people on Earth, according to figures cited by Bluewin. That is a lot more than the about 3 billion alive in 1960, but it is nowhere near infinity. Current United Nations projections, also cited in the reports, expect the global population to keep growing until around the 2080s, peaking at about 10.3 billion before it may begin to decline gradually.
In other words, the “doomsday equation” was a correct description of the past but a poor guide to the future. Scientists now see it as a classic example of the danger of extending a trend indefinitely without accounting for how societies respond to change.
What the Study Got Right
Even though the headline prediction failed, the paper is still discussed because it made a serious point in a memorable way. Euronews reported that the authors’ real aim was to show that unchecked growth cannot go on forever on a planet with limited space, food, water and energy.
That concern has not gone away. Debates over climate change, food security, urban overcrowding and pressure on public services are, in part, debates about how a larger population can be supported sustainably.
Why It Matters for Nigeria and Africa
While population growth has slowed sharply in Europe, East Asia and the Americas, sub-Saharan Africa is now where much of the world’s future growth is expected to happen. Nigeria, already Africa’s most populous country, is projected by the UN to remain one of the most populous nations on Earth through the rest of the century.
For policymakers in Abuja and across the continent, that means the real questions are not about doomsday but about planning: creating enough jobs for young people entering the labour market, expanding schools and hospitals, building housing, and growing enough food. Experts generally agree that investment in education, especially for girls, and in health care are among the most effective ways to manage growth while improving living standards.
So, Should You Be Worried Today?
No. Friday the 13th has a long reputation for bad luck in popular culture, and this one comes with an unusual scientific footnote, but no researcher today believes the world will end because of the 1960 calculation. If anything, the date is a useful reminder to look at population numbers carefully and to plan ahead rather than panic.
