Theorists believe a mysterious planet already hidden in the Solar System will collide with Earth, killing everyone and devastating the planet, sometime this Saturday.
The bizarre claim has been put forward by a number of conspiracy fans, most notably David Meade.
He has tied the disaster to a number of Biblical prophecies and passages, including Revelation 12:1.
This passage reads: “A great sign appeared in heaven; a woman clothed with the sun with the moon under her feet and a crown of 12 stars on her head.
“And being with child, she cried out in her travail and was in anguish of delivery.”
Mr Meade claims the “sign in the sky” refers to the stunning eclipse experienced last month.
He explained: “The great sign of The Woman as described in revelation 12:1-2 forms and lasts for only a few hours. According to computer generated astronomical models, this sign has never before occurred in human history.
“It will occur once on September 23, 2017. It will never occur again. When it occurs, it places the Earth immediately before the time of the Sixth Seal of Revelation.
“During this time frame on September 23, 2017, the moon appears under the feet of the Constellation Virgo. The Sun appears to precisely clothe Virgo.”
Will Nibiru crash into Earth on September 23, ending the world?
Theorists also claim natural disaster signal the approach of Planet X, as the huge planetary body would interfere with the Earth.
They say the high number of serious hurricanes to have hit the Caribbean so early in the season, plus the large number of earthquakes striking across the globe, prove disaster is near.
Mr Meade originally predicted Nibiru would crash into Earth next months in his book ‘The 2017 Arrival’.
However he later revised the date to September 23.
He said: “It is very strange indeed that both the Great Sign of Revelation 12 and the Great Pyramid of Giza both point us to one precise moment in time – September 20 to 23,…
