If I told you the world would end, would you consider me a street corner preacher shouting the words of the Bible, someone long out to lunch and forgot the way back to sanity? Would you think I am a doomsday prophesier, predicting the end of the world in some cataclysmic moment? Would you consider me just a kook who believes anything except reality?
But if I said the world would end in a few billion years from now, I'd be an astronomer simplying telling the truth. So, when someone says the world will end, it's a matter of the old saying, "timing is everything." So who's the fool not to believe the world will end some day, just maybe not in our lifetime?
