The question when will the world end has been asked for centuries, inspiring everything from religious prophecy to scientific inquiry. No credible source offers a single verified date. Instead, researchers assess risks, theologians interpret scriptures, and the Doomsday Clock serves as a symbolic warning. This article examines what science, religion, and risk analysis actually say about the end of the world.
There is no scientific or religiously credible way to predict an exact “world end” year such as 2026, 2027, or 2038. What exists instead are risk assessments, symbolic warnings, and religious interpretations about possible catastrophe, with the Doomsday Clock being the best-known secular example.
What Does Science Say About When the World Will End?
Scientific End (Earth)
~7.5 billion years
When the Sun expands into a red giant.
Scientific End (Humanity)
Unknown
Could be centuries or tomorrow (asteroid, climate, war).
Doomsday Clock
85 seconds to midnight (2026)
Closest to disaster in history.
Most Predicted Date
2026 / 2060 / 2038
Common dates found in religious and pseudoscientific circles.
Key insights from the research:
- The world will end in a scientific sense (Earth destroyed) in about 7.5 billion years, but humanity may end much sooner.
- The Doomsday Clock is at 85 seconds to midnight, the closest ever, due to nuclear risk and climate change.
- Most specific dates (2026, 2027, 2038) are not supported by science or mainstream religious scholarship.
- The most likely near-term extinction threats are human-made (climate, nuclear, AI/bio).
- The Bulletin of the Atomic Scientists created the Doomsday Clock in 1947 as a symbolic measure, not a literal countdown.
- Since 2007, the Bulletin has explicitly included climate change in its assessment alongside nuclear and other global risks.
| Fact | Detail |

| Islamic eschatology | Signs include major wars, Dajjal, return of Jesus. No fixed year. |
When Will the World End According to the Bible and Islam?
Biblical End Times
Christian eschatology offers no single agreed-upon date. The Bible’s Book of Revelation describes a series of events including tribulation, the Second Coming, and a final judgment. Matthew 24:36 states plainly: “But about that day or hour no one knows, not even the angels in heaven, nor the Son, but only the Father.” Many interpretations exist, but no mainstream Christian scholar assigns a specific year.
Islamic Eschatology
In Islam, the end of the world is preceded by major signs: the appearance of the Dajjal (Antichrist), the return of Jesus, the emergence of Gog and Magog, and a period of global justice. These events are described in the Quran and Hadith, but no fixed year is given. The exact timing is known only to Allah. This differs from some Christian groups that have attempted to calculate dates based on biblical numerology or prophecy codes.
Religious end-times prophecies are matters of faith and interpretation, not empirical prediction. No major religion provides a verifiable, calendar-based date for the end of the world.
Is the World Going to End in 2026 or 2027?
No reputable scientific source predicts that the world will end in 2026 or 2027. Claims about an asteroid impact in 2026 have been debunked by NASA. The Doomsday Clock, while set closer to midnight than ever before, does not forecast a specific year for catastrophe. It is a symbolic risk assessment updated annually.
The year 2038 is sometimes mentioned in doomsday discussions, but that refers to a computer software bug (the Year 2038 problem for 32-bit Unix systems), not a global extinction event. It is a technical issue, not an apocalyptic prediction.
Date-specific apocalypse claims are almost always speculative or religious, not scientific. The strongest available evidence supports rising existential risk from nuclear weapons and climate change, but it does not support a definitive prediction that the world ends in 2026, 2027, or 2038.
How Close Are We to the End of the World? The Doomsday Clock and Climate Change
The Doomsday Clock
The Doomsday Clock is a symbolic measure created by the Bulletin of the Atomic Scientists in 1947. It communicates how close humanity is to self-inflicted catastrophe. In 2026, the clock was set to 85 seconds to midnight, the closest it has ever been. This reflects concerns about nuclear risk, climate change, biological threats, and disruptive technologies such as AI. The Bulletin states that the clock is meant to spark conversation about existential risks; it does not claim to predict a specific date for apocalypse. Since 2007, the Bulletin has explicitly included climate change in its assessment, alongside nuclear and other global risks.
Climate Change as an Existential Threat
Climate change is treated by the Bulletin as a major existential threat, but not as a precise clock to a single end date. It is one of several compounding risks that could increase instability and harm over time. The Intergovernmental Panel on Climate Change (IPCC) provides regular reports on climate trajectories, but these are scenario-based projections, not predictions of a specific end date.
Science evaluates probabilities, scenarios, and risk trajectories. It can say certain futures are becoming more dangerous, but it cannot honestly give a verified “end of the world” date from current evidence. Religion often frames end-times through prophecy or theology, but those claims are matters of faith.
Timeline of Scientific and Predicted End-of-World Scenarios
- ~1-2 billion years: Sun becomes bright enough to boil Earth’s oceans. (Science)
- ~7.5 billion years: Sun becomes a red giant, likely engulfs Earth. (Astronomy)
- Now – 100 years: Highest human-extinction risk (nuclear, climate, engineered pathogens). (Risk analysis)
- 2026: Predicted by some pseudoscience (asteroid) – debunked. (Pop culture / fringe)
- 2038: Linked to Y2K38 Unix time bug (computers, not Earth). (Tech myth)
- 2060: Predicted by Isaac Newton based on biblical code. (Historical prediction)
What Do We Know for Certain, and What Remains Unclear?
| Established Information | Information That Remains Unclear |
|---|---|
| The Earth will eventually be destroyed when the Sun dies (7.5 billion years). | Exactly when humanity will go extinct (if not from the Sun). |
| The Doomsday Clock is currently at 85 seconds to midnight. | Whether climate change or nuclear war will cause extinction. |
| Most specific apocalyptic dates in history (e.g., 2012, 2026) have passed without incident. | The exact timeline of biblical or Islamic end-times prophecies. |
Why Does the Question “When Will the World End” Persist?
The question persists across cultures and history because it touches on fundamental human concerns about mortality, meaning, and the future. Psychologically, the idea of a definitive end can provide a sense of closure or urgency. There is a critical difference between the “end of the world” (the planet’s destruction) and the “end of humanity” (civilization’s collapse). The Doomsday Clock serves as a metaphor for the latter, not a literal countdown to the former. Understanding this distinction is central to separating science from speculation.
What Do the Sources Say?
“The Doomsday Clock is a design that warns the public about how close we are to destroying our world with dangerous technologies of our own making.”
Bulletin of the Atomic Scientists
“What we do know is that if nothing else causes the end of the world, planet Earth will come to its end when the Sun dies in about 7.5 billion years.”
NASA / Sky at Night Magazine
“But about that day or hour no one knows, not even the angels in heaven, nor the Son, but only the Father.”
Bible, Matthew 24:36
What Should You Take Away from This?
The strongest available evidence supports rising existential risk, especially from nuclear weapons and climate change, but it does not support a definitive prediction that the world ends in 2026, 2027, or 2038. The most reliable takeaway is that humanity faces serious, self-inflicted threats that demand attention, but that no honest scientific or religious authority claims to know the exact date. For ongoing updates on existential risks, monitoring the annual Doomsday Clock announcement and reports from NASA and the IPCC is the most informed approach.
