I have to disagree with u there... Obviously the dense energy was an effect of something. Obviously the Big Bang was the effect of etc. We might not know what or why it happened, but we don't even know what's in all our oceans and how big they really are because we've only discovered less than five percent. We're not technologically and intelligently advanced enough to figure this out at the moment. That does not mean nothing caused it that just means we do not know the cause of it.
