There is a Wikipeida page citing the ~200 times there have been serious predictions that the world is ending. Here are my favorites:
#126: In 1997 the “Heavens gate cult” came to believe that an alien spaceship was trailing a comet, apparently looking to destroy our planet. Everyone in the cult committed suicide, believing their souls would board the spacecraft to be taken onto a plane above human existence.
#123, #124, #158, and #159: Harold Camping, an American Christian radio broadcaster, predicted the end of the world four times between 1994 and 2011. He was wrong all four times, and died in 2013.
#169: In 2017, David Meade predicted that the rapture would occur that year. It didn’t. Then he predicted it would happen on April 23, 2018. It didn’t.
#171: Ronald Weinland predicted the world would end in 2011, 2012, 2013, and 2018. He’s now got it slated for June 9, 2019.
It’s amazing to what lengths people will go to find meaning where there is none.
Another example: Apparently the planet Mercury is in retrograde this month, and a whole lot of delusional people think this is a bad omen, despite the fact that astrology has long been known to have no meaning whatsoever.
