Basically, Chaos theory says that the world is a chaotic interconnected web of events, and that even the slightest event can impact everything it's connected to. For example,
…the fact that I stopped to write this explanation affects the world in a multitude of incalculable ways. In one way, it took a few minutes from my life, and those few minutes could impact me forever. For the rest of my life, I will be a few minutes behind what I would otherwise be. There are people that I may never meet because of it, and people that I may meet that I otherwise wouldn't. In turn, this affects their life, as their knowledge of me and the time they take to interact with me sets them a certain amount of time behind. This can go on forever.
