The Earth is about to be destroyed on Sept. 23, according to a Christian numerologist, which is a bit of a problem in that Sept. 23 has already passed. But don’t worry, the man who came up with this theory has decided to make a few modifications to his doomsday prediction.

At first, Christian numerologist David Meade made headlines because he confidently predicted that Luke 21:25-26 heralds the end of the Earth on Sept. 23, and Hurricane Harvey and the solar eclipse were signs of this. But as the date neared, he suddenly got cold feet, adjusting his prediction to a more tame version where the Earth will change dramatically by October but in some unspecified way.

Here’s the verses he based his original prediction on: “25: There will be signs in the sun, moon and stars. On the earth, nations will be in anguish and perplexity at the roaring and tossing of the sea. People will faint from terror, apprehensive of what is coming on the world, for the heavenly bodies will be shaken. 26: Men’s hearts failing them for fear, and for looking after those things which are coming on the earth: for the powers of heaven shall be shaken.”

This prediction is a variant of the Nibiru cataclysm end-times theory that has been around since the 1990s, where a huge planetary object either collides with Earth or comes near Earth causing the apocalypse and ushering in Christ’s second coming.

“The Nibiru cataclysm is a supposed disastrous encounter between the Earth and a large planetary object (either a collision or a near-miss) which certain groups believe will take place in the early 21st century,” reads an excerpt from Wikipedia. “Believers in this doomsday event usually refer to this object as Planet X or Nibiru. The idea that a planet-sized object will collide with or closely pass by Earth in the near future is not supported by any scientific evidence and has been rejected by astronomers and planetary scientists as pseudoscience and an Internet hoax.”
