When Will the World End? Doomsday Theory Says Fiery Hell on Earth Kicks Off Saturday

The world will be vaporized in roughly 7 billion years, when the sun expands into an enormous red giant star and explodes across the solar system. Or, perhaps a 60-mile-wide asteroid will crash into Earth well before then, ending life as we know it.

The scientific community has said for decades that either of these apocalyptic scenarios could ultimately provide the final nail in our planet's coffin, citing fact-based research and historical data to back up such bold assumptions. Doomsday theories continue spreading online almost annually, however, leading countless readers to believe the end of time is much more imminent than originally anticipated—without any tangible evidence or support.

The latest prediction comes from the evangelical Christian publication Unsealed, and says the end of the world will occur—get ready!—on Saturday. A four-minute video the site created promising to explain how the world will meet its ultimate demise has been going viral recently, spurring a number of copycat apocalyptic predictions for the upcoming weekend.

In the Unsealed video, a mythical pregnant woman is attacked by a seven-headed dragon in the sky. Onscreen text claims images of the two figures will appear above Jerusalem and Israel on Saturday, before the heavens above open and unleash fiery hell on Earth.

September 23 marks 33 days since last month's historic solar eclipse, a "very biblically significant, numerologically significant number," David Meade, a researcher dubbed a "Christian numerologist," told The Washington Post Sunday.

"Jesus lived for 33 years. The name Elohim, which is the name of God to the Jews, was mentioned 33 times [in the Bible] … The world is not ending, but the world as we know it is ending," he said. "A major part of the world will not be the same the beginning of October."

The biblical apocalypse also involves Nibiru, a supposed brown dwarf that's surrounded by other planets and set to strike Earth in just a matter of time.

The only problem with this theory? It was already debunked years ago by a senior space scientist for NASA.

"In the inner solar system, we see planets with stable orbits, we see the moon going around the Earth," NASA scientist David Morrison explains in a video from 2012 titled Nibiru Does Not Exist. "The very existence of this stability in the inner solar system proves that no rogue planet, no interfering object has come through the inner solar system in at least a million years.

"Please get over it," Morrison added. "We don't need to worry about this hoax."
