Okay, I'm a firm believer in a fixed future. I believe that every event is caused and affected by a preceding event and that if the state of everything in the universe (infinite or otherwise) was known, the next states would be predictable. I am willing to accept that perhaps I only believe this because I am ignorant to Quantum Mechanics, which if I'm correct suggests that everything is probabilistic. I simply cannot imagine a world where there are a number of possible outcomes each with a probability of occurring. I know it only really applies to quantum level particles, but this would effect the greater world as we know it and therefore directly affect our future lives. As far as I'm concerned, there is only a single future ahead of me, not multiple. So to allow you to convince me otherwise, I'm going to present you with a simple problem: I have a particle that apparently has a 50% probability of being in each of states 0 or 1, according to Quantum Mechanics. When I observe the particle, it is in state 0. I say "This particle was always going to be in state 0 when I observed it and that was the only future ahead of the particle." So the question is: How could any scientist possibly disprove my statement through experiment? Yeah, you could show me something that happens approx. 50% of the time and doesn't happen the rest of the time. But I could say it was always going to be like that. That's not a probabilistic future. That's just the way the laws of (non-quantum) physics made it happen (which happens to have a statistically 50% chance). I hope you all understand and I hope that if I've totally misinterpreted quantum physics that you'll set me on the right path. Thank you.
