The argument that has never once been settled, despite centuries of attempts, is the one about when, and how, the world ends. Every generation has had its candidates: a comet, a war, a divine reckoning, a calendar that runs out of dates. Every single one of those predictions has been wrong. And yet, right now in 2026, more than 100 million Americans believe the world will end within their own lifetimes.
The Long History of Failed Prophecies
Predictions of apocalyptic events that will result in the extinction of humanity, a collapse of civilization, or the destruction of the planet have been made since at least the beginning of the Common Era. Most are rooted in Abrahamic religions, often tied to the eschatological events described in their scriptures. The word “eschatology,” for those who didn’t spend time in a theology class, simply refers to beliefs about the end of history: death, judgment, the final fate of humanity.
Christian predictions typically refer to events like the Rapture, the Great Tribulation, the Last Judgment, and the Second Coming of Christ. These end-time events are normally predicted to occur within the lifetime of the person making the prediction and are usually derived from the Bible, particularly the New Testament.
Martin Luther believed the Second Coming was imminent and wrote extensively about the end of the world being near during his own era. Cult leader Jim Jones predicted the world would end in a nuclear apocalypse by 1967. Pope Innocent III in the 13th century chose the year 1284, because that was exactly 666 years after the emergence of Islam in 618.
When 1284 came and went, people didn’t abandon the idea of an ending; they adjusted the math. When Harold Camping, an American radio evangelist, predicted Judgment Day for May 21, 2011, and that date passed without incident, his followers didn’t walk away from end-times belief. Many simply accepted a revised date. Psychologists call this “belief perseverance”, the tendency to hold onto a conviction even when the evidence against it is overwhelming, and apocalyptic movements have been running a masterclass in it for two thousand years.
The Mayan calendar panic of December 21, 2012, followed the same playbook. The calendar didn’t actually predict the end of the world; it predicted the end of a 5,125-year cycle, more analogous to the clock ticking over from 1999 to 2000 than to literal global destruction.
Why Our Brains Are Wired for This
The persistence of end-of-world predictions isn’t evidence of mass irrationality. It’s evidence of how human cognition actually works under conditions of fear and uncertainty. Psychologists have long known that humans struggle with uncertainty about the future. One influential framework, Terror Management Theory, proposes that people construct belief systems partly to manage anxiety about mortality. Cultural worldviews provide a sense of continuity and meaning that buffers the fear of death. Apocalyptic narratives may function as civilizational-scale versions of this coping strategy, transforming uncertainty into a story.
A story with an ending is, paradoxically, easier to live inside than one that has no ending at all. Knowing the world will end on a specific date, for a specific reason, is in some ways less frightening than confronting the open-ended uncertainty that defines actual life. It converts a vague, diffuse dread into something with a plot.
Psychologists identify several reasons people believe in modern apocalyptic predictions: mentally reducing the actual danger in the world to a single, definable source; an innate human fascination with fear; personality traits of paranoia and powerlessness; and a modern romanticism related to end-times, resulting from its portrayal in contemporary fiction. We have trained ourselves, through decades of film, television, and fiction, to find apocalyptic scenarios aesthetically appealing.
A 2026 study in the Journal of Personality and Social Psychology surveyed 1,409 religiously diverse Americans and found that about one-third agreed the world would end within their own lifetime. The research reveals that what people believe about the apocalypse, when it will happen, who controls it, and what comes after, can dramatically shape their attitudes toward climate change, pandemic response, nuclear conflict, and emerging technologies.
Someone who believes humans are causing the apocalypse through climate change responds very differently to environmental policy than someone who believes the end times are controlled by divine prophecy. Those who believe the end is near and that humans are causing it perceive greater risk and support more extreme action to address threats. Those who think divine forces control the apocalypse are significantly less inclined to support preventive measures.
When Science Takes a Turn at Prophecy
If religious end-of-world predictions have dominated the first two thousand years of this conversation, the last century introduced a different kind: the secular, scientific doomsday framework. And in 2026, it’s making some of its most urgent claims yet.
The Bulletin of the Atomic Scientists was founded in 1945 by Manhattan Project scientists at the University of Chicago. Two years later, they created the Doomsday Clock, a symbolic device using the imagery of a clock face to represent how close humanity is to self-destruction, with midnight representing catastrophe. When the clock was created in 1947, the greatest danger came from nuclear weapons. Climate change was incorporated into its deliberations in 2007.
On January 27, 2026, the Doomsday Clock was set at 85 seconds to midnight, the closest it has ever been in its history. Since the countdown began in 1947, the Bulletin has varied its assessment between as far as 17 minutes from midnight and this year’s 85 seconds. The lowest-ever risk was recorded in 1991, the year the Cold War officially ended and the United States and Russia began making significant cuts to their nuclear arsenals.
The major factors driving the 2026 reading include growing nuclear weapons threats, disruptive technologies like artificial intelligence, multiple biological security concerns, and the continuing climate crisis. The Bulletin noted that Russia, China, the United States, and other major countries have become increasingly aggressive, adversarial, and nationalistic, with hard-won global understandings collapsing and winner-takes-all competition accelerating.
The Bulletin’s Clock is deliberately not a prediction. Its creators are explicit about this. As Alexandra Bell, the organization’s president and CEO, stated in the 2026 announcement: “The clock does not predict the future. It illuminates our current reality. The clock has turned back before. And it can again.” A clock that can turn back is an argument for action, not surrender.
The Scientific End of Earth
If nothing else causes the end of the world first, planet Earth will come to its end when the Sun dies in about 5 billion years. At that time, the Sun is on course to swell into a huge red giant that will consume the inner planets, including Earth.
A 2021 study published in Nature Geoscience by researchers Kazumi Ozaki of Toho University and Christopher Reinhard of the Georgia Institute of Technology modeled Earth’s long-term atmospheric evolution. Their results predict that Earth’s oxygen-rich atmosphere will likely last only another billion years, long before the Sun consumes us, as rising solar radiation gradually strips away the conditions that make complex life possible.
This timeline sits so far outside ordinary human comprehension that it’s almost useless as a source of dread. A billion years from now is not something you can prepare for in any practical sense. What it does offer is perspective: the universe operates on scales that dwarf the apocalyptic dramas we stage for ourselves. The terrifying science facts that tend to unsettle people most aren’t the ones billions of years away, they’re the ones embedded in the conditions we’ve already created.
The more immediate scientific concerns are the ones the Bulletin tracks: nuclear arsenals that haven’t shrunk, a climate that’s warming faster than models predicted, artificial intelligence developing faster than governance frameworks can follow, and biological research capabilities that have expanded the range of who can cause catastrophic harm. Four developments in particular have increased the possibility of bio-catastrophe: research into self-replicating “mirror life,” AI tools that can design biological threats, state-sponsored biological weapons programs, and the dismantling of US public health infrastructure.
None of these is a prophecy. All of them are contingent, dependent on decisions that haven’t been made yet. That’s the key difference between religious end-of-world predictions and scientific risk assessments. One treats the ending as fixed; the other treats it as something humans can influence.
The RaptureTok Moment and What It Tells Us
In September 2025, a wave of Evangelical Christians gathered online to share their conviction that the Rapture, the moment when the faithful are taken to heaven before a period of global tribulation, would arrive on September 23 or 24 of that year. The hashtag #RaptureTok went viral. A number of people sold their homes and possessions and began preparing for an ending they believed was days away. The date passed. There is no report of anyone being taken anywhere.
#RaptureTok illustrated how end-of-world beliefs serve as a form of community: a shared story that creates intense social bonds, a framework for understanding current events, and a way of locating yourself as significant within a vast and often indifferent universe. The people preparing for the Rapture weren’t stupid. They were doing something deeply human, finding meaning in a story about ultimate stakes.
The research backs this up. Apocalyptic thinking crosses the lines that divide Americans on nearly everything else. Evangelical Christians, secular doomsday preppers, atomic scientists maintaining the Doomsday Clock, and climate activists warning of environmental collapse all hold versions of it, even if the specifics look nothing alike. The scientist adjusting the Doomsday Clock and the prepper stacking freeze-dried food in a garage are drawing on the same underlying cognitive architecture. The stories they’re telling themselves are different. The psychological function is remarkably similar.

What to Do With the Weight of It
The question most people eventually land on isn’t really whether the world will end. It’s whether the specific, near-term ending that fills the news and their dreams is real, and what they should do about it.
The 2026 psychology research offers a genuinely useful finding here. “We found that believing the world will end soon actually predicted greater support for extreme action to address current threats,” researcher Matthew Billet explains. “It’s not that these believers don’t care about the future. They care deeply, but the specific content of their beliefs shapes how they want to respond.” Believing the end is near doesn’t automatically produce passivity or despair. The details of your belief, specifically, whether you think humans caused the problem and can therefore address it, determine whether that belief leads toward action or resignation.
A climate activist and a divine-prophecy believer may both think the world is in serious trouble. But one of those belief structures generates pressure to act, and the other generates permission to wait. Rather than dismissing apocalyptic thinking as irrational, Billet argues that understanding these beliefs is essential for effective communication and policymaking in an increasingly divided society.
The history of end-of-world predictions isn’t really a history of wrong answers. It’s a history of human beings trying to make sense of circumstances that felt overwhelming, plague, war, technological change, social collapse, by reaching for the most extreme story available. The world kept not ending, but the conditions that generated the predictions often were genuinely dire. The prediction was wrong. The fear behind it wasn’t always.
What the Doomsday Clock at 85 seconds, the psychology research, and two thousand years of failed prophecies all share is this: humans are extraordinarily bad at knowing when the ending is actually near, and extraordinarily good at sensing when something real is wrong. The second instinct is worth paying attention to. The first is probably best held loosely.
