When & how is going to be the end of the world?

no matter when the doomsday comes, we just need to live our life as usual. most importantly, we must be happy everyday, then if that day really comes someday, we will have no regret. when this world come to the end, I believe a new world will come, though maybe we have no hope to live in the new world. just take it easy about this.

its difficult to tale whether world will end or not . to talk scientifically earth can be affected by some geographic activities but its after long time or might be never

Sorry to say, but it's more than just a nasty rumor, it's fast becoming a scientific fact. We do have the power & means to both individually & collectively postpone it or reverse it if we wish to if we act very soon. Unfortunately this topic has been covered in great detail many times before now, & much has been written on it. It is not certain that the whole world will come to an end in an instant, or if it will occur over a short period of time after the frequency & severity of natural & unnatural disasters, disease, etc reach a grand scale.

Some says the year 2012 according to Mayan belief but I don't buy it. Because I believe nobody in this world know when and how. According to bible account nobody knows except God when the end of the world but how God said not by water but by fire... thanks, see you around.
