hmmm;

my 2 cents is that, and no offense to our OP,
folks around here are getting to the point where a link to a utoob video as the majority of only content of the OP and purported to be 'evidence' of something, is becoming less and less tolerated (apologies for the poor grammar)

yes, we cant keep all of the people happy all of the time, but we can keep some of the people happy some of the time

do you have any more information or is it all in the vid?

if you want an opinion, here's mine
as a student of prophecy and in particular the book with more proven prophecies than any other, the bible, there are many many things that 'must take place' before the 'apocalypse'

all these cosmological 'possibilities' can be seen by some to partly fulfil some prophecies, however the prophecies must be fulfilled in EVERY detail and that is not the case here

all this 2011/2012 stuff is part of the ploy to take our minds off creating our own future and valuing our freedoms, and exchanging this willingly for the future 'they' want to give us, one without freedom

cheers

Why does everyone want to see the planet end?

Youtube video makers are... shall we say, a little dramatic and will pile together loads of crap to scare people, get their usually moot point across, and try to persuade as many people as possible that their tripe is factually true and correct.
I didn't even bother watching this, because to be frank, if you've seen one Youtube video about the end of the world, you've probably seen them all.
In future, use YT with a bowl of salt, and take a pinch every time you see something 'controversial' lol
And SCRUTINIZE anything that says they present evidence. Usually it's a bunch of jargon they've pulled off another site that they don't properly understand and they just fill in the blanks they don't get with something they think it could mean.
