We all know beyond the universe, there's nothing. How come is that possible? Theory says the big bang happened, and that theory has been accepted since it was "released". But where was the energy that caused it? And how did it existed, if there was nothing? Is there anything in the "nothing"? And, if we talk about religion, how did god exist? Who made it? How was he created if there was nothing? Some people say it created himself, but how the heck that happened if there was nothing?

I realise this may not be satisfactory, but many philosophers and scientists think that we cannot know the answers to your questions. You start by saying that we know that beyond the universe there is nothing. But this may be one of the things that we cannot know. If there was something, something physical, before the universe then this would be the origin of the energy that gave rise to the Big Bang. One possible explanation, then, is that there are or have been many other universes (the multiverse theory). Of course, there is considerable difficulty (impossibility?) in collecting any empirical evidence for this theory, since such evidence would need to come from beyond the limits of spacetime itself. But perhaps something - some universe or other - has always existed; there was never nothing. Many people find this claim more puzzling than the thought that once there was nothing, and then there was something. But why? The philosopher David Hume asked us to consider the limits of our knowledge about...
