Scary at first but when you do start to actually look into it you think nah. Firstly they say Nostradamus predicts a comet to hit the earth. Have a look at his prediction for 1999;
"In the year 1999 and seven months
The Great, King of Terror shall
come from the sky. He will bring to
life the King of The Mongols. Before
and after, Mars reigns happily."
Did the great king of terror come from the sky in July 1999, the only thing I can think of was that Serbian war and that's not really the king of terror from the sky. Here's another brilliant prediction which apparently predicts 9/11.
"In the City of God there will be a great thunder,
Two brothers torn apart by Chaos,
while the fortress endures, the great leader will succumb",
The third big war will begin when the big city is burning"
Assuming you call new york the city of god (But why) and the world trade center brothers (although "twin towers" But still far fetched) And you call Bush the great leader (OK now I'm trying not to laugh) And you call the war on terror WWIII (Lets say at the most 1.5 million have died if you compare that to the 50 million who died in WWII its not really a world war) If you believe that then it sounds a bit like 9/11 but its still very fade.
Now apparently Einstein predicted a polar shift and I'm not going to deny that but I think the consequences of a polar shift are quite exaggerated I don't really see what might happen, the birds might mess up when there going south but I don't see anything serious happening (Maybe SS or Neil can help here)
Also they say there will only be one more pope, have a look;
In extreme persecution, the seat of the Holy Roman Church will be occupied by Peter the Roman, who will feed the sheep through many tribulations; when they are over, the city of seven hills will be destroyed, and the terrible or fearsome Judge will judge his people. The End.
This doesn't mean the world will end maybe people will finally stand up to this hypocritical and robbing system, or maybe nothing will happen I personally don't let prophecies rule my life and I don't think any intelligent person should. But what do you think?
