I was in the shower yesterday, when I thought:
Hang on; If you had an ultracomputer, scanned every particle in the universe, and simulated it at x2 speed, couldn't you predict the future?
Later on, I was watching a documentary about Quantum physics, and that says that anything can happen at subatomic scale for no apparent reason. crucially, THIS CAN NOT BE PREDICTED. Therefore, you only have about a 99% accuracy, and that's all that matters. For example, you could say that the sun will rise tomorrow. It might simply disappear altogether for no apparent reason. Or that stepping into an acid pool will kill you. again, a Quantum Coincidence (Yay, I coined a term!) might occur and the acid might turn into water. OK, hold on, let me start again...
A 100% accurate future prediction is impossible, since seeing the future 100% accurately would result in the future being changed. This is not possible. It is a paradox. Put it this way;
say the machine predicted your death. You would take action against that and the machine would be wrong. But it cannot be.
Now, say the machine predicted you would take action. You would be complacent, not bothering to take action since the smachine says you will live.
This is like the doctor paradox. If you go to the doctor, you will get well. But, since it was predicted you would get well, why bother?
Conclusion: 100% accurate time prediction is impossible.
Conclusion: 99.9999999999999999% accurate prediction is possible.
Conclusion: The Human Brain can create paradoxes.
Therefore: The Human Brain is a Quantum Engine
Therefore: Paradox resolved
