I think that everything that is going to happen is sort of predetermined. I mean if the current state of the entire universe and the position of every subatomic particle is X and all the laws of physics combined are F, then a simple F(X) = Y equation happens, where Y is the state of the universe during the next sampling. The future would be completely predictable if you knew the position of all the quarks and other particles and all the laws of physics, you had an extremely fast computer, and you could correct for slight errors caused by the universe not having a minimum time frame, which you would have to add in your calculation program.
