End of the world.....2012?

ok so i was talking to my husbands friend(hes into all that astro/future/planets stuff)anyways he said that in 2012 the planets are suppose to align and its suppose to do major damage weather wise and anyways the world is coming to an end.Now i know that 2000 we are suppose to go kapput and here we are but seriously its scary to think like that.Whats your opinion.Is there anyone who thinks this is true.Are there any facts.
