It depends of your point of view to answer this question. at the science, we need a observer for definitions. that is what happened is really depend on how we record it? So when you are a physician or you are a philosopher ,a poetry or a governor, your answer will be different. if I want answer this question, really I have to say I don't know. in my opinion, who say that know what is the world, his/her definition will be incomplete. The world is infinity and with out limits and we are just watching it! it come out of us only, just watching, recording and analysing for our comfortability.
