Religious figures, scientists, technologists and others have long heralded the ending of the world in what in some traditions is called the apocalypse. This site tracks those failed predictions in the past and charts those coming up in the future.

Halley's comet is named after the astronomer who predicted its next appearance

Edmund Halley realized that historical accounts of a celestial object passing in the night sky in 1531 and 1607 referred to the same object he observed in 1682. By applying Newtonian mechanics to his observational data, he calculated its orbit and accurately predicted its return in 1758.

Ancient Greek astronomer Hipparchus created accurate maps of the night sky way ahead of his time, with coordinates sometimes within a single degree of modern values.

Some online users believe gravity will 'switch off' for 7 seconds in August 2026

Conspiracy theorists believe NASA is preparing for the gravity blackout under a classified operation called "Project Anchor." They speculate that the purpose of the secret project is to test whether Earth can survive such an event. NASA has rejected the claim. Considering the physics of a gravity blackout, the outcome would likely be chaotic but not total destruction.

A year's name is determined by the 12-year Chinese zodiac cycle

According to Lunar New Year traditions, the coming year gets its name based on the 12-year Chinese zodiac cycle. The animals, in order, are rat, ox, tiger, rabbit, dragon, snake, horse, goat, monkey, rooster, dog, and pig. 2026 is the Year of the Horse, an animal known for its strength and momentum, while 2027 will be the Year of the Goat.

In 2025, astronomers confirmed that Neptune has auroras, which were observed at mid-latitudes because its magnetic field is tilted 47 degrees from its rotation axis.

Unlike quantum mechanics, classical physics suggests free will does not exist

Models based on Newton's laws of motion suggest all actions are predetermined and must follow specific trajectories and outcomes, such that everything that will ever occur in the future has already been set in motion by past causes. However, quantum mechanics challenges determinism because it is based on probability, where no outcome is certain.

More than 39 million people are expected to die from antimicrobial resistance by 2050

In 2024, researchers published an incredibly detailed study aimed at predicting the real-world impact of antimicrobial resistance over the next 25 years.

What was the longest year in history?

In 46 BCE, Julius Caesar declared the year would last 445 days. This four-minute podcast and accompanying article explain why. Caesar wanted to make the following year start after the winter solstice, an achievement attainable due to his tinkering with the Roman calendar. But to start the year right, Caesar had to stretch the transitional year, leading to the creation of Caesar's Year of Confusion, the longest year in history.

Experts say 2023 was a welcome year for Napa's wine

One theory suggests real estate markets follow a predictable 18-year pattern

The theory dictates that real estate markets tend to experience about 14 years of growth, including a mid-cycle dip, then experience four years of decline. Real estate experts in London discuss the theory in an article.

As of 2026, 14 of Neptune's 16 moons have been named for mythological figures, with Triton, the largest of them, orbiting backward, or in retrograde.

Astronomers inferred Neptune's existence through mathematics while attempting to explain irregularities in Uranus' orbit, but Neptune had been directly observed 234 years earlier by Galileo.

Neptune is the farthest planet from the sun, orbiting 30 times farther than Earth and taking 165 years to complete one revolution.

Twain claimed to possess 'mental telegraphy'

The legend of the Chinese zodiac involves a race between animals

The legend of the Chinese zodiac says that to help people keep time, the emperor of the gods established a 12-year cycle, with each year symbolized by a different animal.

What do your dreams mean, according to science

Humans have been interpreting dreams as signs from deities, spirits, or the psyche for ages, and research shows that reflecting on and analyzing one's dreams can be beneficial. In alignment with dreams' elusive nature, they have no objective or clearly assigned meaning. However, variations of common dreams, such as a surprise exam in a forgotten class, are rife with shared primal fears.

For most of recorded history dreams were considered divine in origin.
