Nobody knows really when the world is going to end!
We do know, however, that there is ABSOLUTELY NOTHING we can do about it anyway and that one 일 that the world will come to an end. It was predicted that the end was coming in the late '80's then it was supposed to end in the 년 2000 then it said to be 2012 and now all of a sudden it's May 21,2001.
Maybe, maybe not. If it does end, then there's nothing we can do about it. I'll be partying hard with 예수님 anyway XD I personally don't believe that tomorrow is specifically the 일 in which the world ends.
