Free will is the idea that you can do whatever you want, because, like the rest of the universe, you are unpredictable. No one could truly predict that you would pick your nose just now...or decide to scratch your head. If everything you do could be predicted, you would not have free will, because your every move could either be offset, or inhibited altogether. And, for every thing you do, you only add to the entropy (unpredictability) of the universe.

This is the closest analogy I can make to the idea that the universe, too, has a free will, and cannot be predicted, offset, or inhibited, in which case it cannot be preordained...at least not its ending...only its beginning. And if anyone could start such an experiment without even a vague idea of what the results would be, or how the experiment would react, I'm not so sure he or she's the kind of person I wanna put all my faith in. *smirk*
