Thanks for the best laugh I've had all day! I love how she predicted this Nibiru would destroy the Earth in 2003. Um, oops, meant 2012. Two years from now it'll be Um, oops, meant 2022.
Just off the top of my head:
Jehova's Witness cult said Christ would return and end the world - in 1914. Oops.
Comet Kohoutek in 1973 was fearmongered as a harbinger of Christ's return, start of the apocolypse, etc. So, the world ended in the early 1970's.
In the early 1980's a lot of planets were on one side of the sun. Their combined gravitaiton pull (or so the doomsayers said) ripped the Earth apart and sent chunks of broken planet into interstellar space. Hmmm.
Some guy went around selling a book "88 reasons Christ will return in 1988". Wait, didn't he already come in 1914?
Nostradamous predicted the end of the world, it happened in 1999.
Y2K, all computers failed, the remenants of humanity are now living as hunter-gatherers amid the ruins of a fallen technological society. You noticed that, right?
The secret planet Nibaru passed by the Earth in 2003, shifting the Earth's axis and destroying most life on earth.
The Mayan calendar resets in 2012, so the world will end.
Nibaru passes Earth (again?) in 2012, so the world will end.
This needs much further discussion. Let's talk about it in 2013. We'll still be here.
(Why don't the nutjobs ever say, "I have studied the ancient scrolls, and have pinpointed the end of the world. It will be... last week.")
