There are rumours, but I don't listen. Even if it is going to, can you imagine the panic it would cause if people knew? The world could end at any moment, for any number of reasons that are totally out of our control - it was only by amazing chance that we even came to exist in the first place. However, you can't let fear of something that may or may not happen dictate your life. Live life to the full and when the end comes (whether that's just your death or everyone's!) you'll be happy you did.
