VERDICT: FALSE — The world will not end on Friday, 13 November 2026. A real 1960 scientific paper is being twisted into a doomsday prophecy it never made.
The claim
In the past week, posts across TikTok, Instagram and Facebook have warned that the world will end on Friday, 13 November 2026. Some versions say humanity will be “squeezed to death” by overpopulation. Others claim a global cyberattack will strike that day, cutting power and the internet. One Instagram carousel carrying the claim drew thousands of likes and hundreds of comments within days of posting, and news outlets in several countries have reported the date as one of the most widely discussed on social media in recent days. A conference in Vienna even took the prediction as its starting point at the end of October.
The facts
The paper at the centre of all this is real — and it says nothing about the world ending. On 4 November 1960, the journal Science published “Doomsday: Friday, 13 November, A.D. 2026” by physicist Heinz von Foerster and his colleagues Patricia Mora and Lawrence Amiot. Its subtitle gives the game away: “At this date human population will approach infinity if it grows as it has grown in the last two millenia.” The authors fitted 24 historical population estimates to a curve and found that if growth kept accelerating exactly as it had for 2,000 years, the maths would blow up — the population tending towards infinity — in November 2026. It was a mathematical singularity, a warning about unchecked growth, not a forecast of an asteroid, a war or any physical catastrophe. The date was not handed down by the equations alone: 13 November was von Foerster’s birthday — he would have turned 115 that day — and the Friday-the-13th timing gave the paper its memorable title.
The growth the model assumed stopped happening decades ago. Von Foerster’s curve tracked history well until around the 1990s, then reality parted company with it. Global population growth peaked in the 1960s, and the global birth rate today is roughly half what it was when the paper was written. Families got smaller, almost everywhere, and the acceleration the model depended on never arrived.
The United Nations’ latest numbers tell a very different story from the viral posts. In World Population Prospects 2024, the UN projects the world’s population — 8.2 billion in 2024 — to keep growing for another 50 or 60 years, reaching a peak of around 10.3 billion people in the mid-2080s, then declining gradually to about 10.2 billion by the end of the century. No mainstream projection has the population anywhere near infinity, and none has the world ending in 2026.
The cyberattack version has even less behind it. It traces to a social media user calling himself Wesley, who claimed, citing unidentified sources, that a global cyberattack would strike on 13 November. No government or cybersecurity agency has issued any such warning, and no evidence supports it. Related dates circulating alongside it — 17 November, and 20 November, tied to an episode of The Simpsons — are separate rumours with no source at all.
It is not the first viral scare to collapse on contact with the evidence. A recent claim that Kim Jong Un had died fell apart the same way, against fresh photographs and an intelligence assessment — and forecasting sudden catastrophe is something science struggles with even in fields with far better data, as seismologists still cannot predict earthquakes.
Verdict
FALSE. The 1960 paper is genuine; the doomsday reading of it is not. Von Foerster and his colleagues modelled what would happen if two thousand years of accelerating growth continued unchanged. It did not. Birth rates fell, growth slowed, and the UN now expects the world’s population to peak in the 2080s — not to shoot towards infinity next Friday.
Why it matters
Doomsday dates are not harmless fun. Coverage of the scare describes people stockpiling food and bracing for blackouts, and every fake deadline that passes quietly teaches audiences the wrong lesson twice over: first, that science can be read as prophecy, and then that scientists cannot be trusted when their “predictions” fail. When a genuine warning does come — a real hazard with a real deadline — an audience burned by invented doomsdays is less likely to listen. That is the damage these posts do, and it is why the record is worth setting straight before Friday arrives.
