There is a paragraph written by Nostradamus going around that is being presented as evidence that the LHC super collider is going to bring the end of the world (or at least mess it up a lot). Century 9 Quatrain 44 reads:
Leave, leave Geneva every last one of you,
Saturn will be converted from gold
to iron,
Raypoz will exterminate all who oppose him,
Before the coming the
sky will show signs.
Now those of you that knows me knows that I don't think the LHC will destroy the world. In fact I'm very excited at the prospect of science finally finding the Higgs Boson. Still, I've been wrong enough times before to at least be willing to entertain the notion that the world might end. Lets take a look at the paragraph above.
First, a little background on Nostradamus check this link.
So the first line is telling us to leave Geneva. As can be seen in this map, the LHC is close to Geneva:

The next line mentions Saturn will be converted from gold to iron. Saturn, the ringed planet, or Saturn, the titan? I'm going with ringed planet and I'm going to say this is a way of describing the giant ring of the particle accelerator. The LHC will be accelerating and colliding lead, which I sometimes confuse with Iron, could this be what Nostradamus did?
The third sentence is intriguing in the use of the phrase Raypoz which suggests a ray of positrons or perhaps Raymond Pozo a dominican republic singer who according to Nostrodamus, will destroy anything that opposes him.
Finally he speaks of signs in the sky. These are always bad, especially comets and eclipses, but I don't know if there have been any of these in Geneva lately, if there have been, please let me know.
The good news is that Nostradamus seems only concerned with the region around CERN which means those of us watching form the sidelines are probably safe, for now.
