Let's say we observe a quantum event that is said to be "random" or uncertain and (hypothetically ) we travel back in time to one hour before that event.
We would then know the future event because we had already witnessed it. However , would we then be able to say that this quantum event HAS to happen or is inevitable? Presumably we would have to say it was inevitable , wouldn't we? However if we did say this then that would mean (would it?) that this event must be caused by something that forces it to happen (deterministically) because unless it is a determined event then how could it be said to be inevitable?
However, this would clash with Heisenbergs Uncertainty principle would it not? Such an event could no longer be random. Theoretically , the only thing we could say that made much sense would be that this event did happen and that it would be known to happen an hour beforehand but that also on another level it is not a determined or inevitable event becuase the event is still uncertain.
Would this prove that (at least theoretically) it might be possible for a future event to be known to happen but that event is not "certain" also until the very moment when it HAS happened.
I say this because maybe it has a bearing on the "how can God know my future but at the same time I can have free will? " debate.
Presumably God would know all uncertain quantum events that ever happened or will happen. He would have to know them being omniscient. However , if science is right then some quantum events are supposed to random and uncertain so even God could not "foresee" them until they happened. God would not be able to predict such events because there would be no logical way of doing so. The only way he could know would be as they happened. But he would still know "in advance" because he knows every point in time past . future, right from beginning to end.
We could then say that if God exists then there must be at least one event that was not determined that God would know was about to happen but that that event was also not inevitable or foreseeable because it was uncertain right up until the very moment when it became a reality. In one sense God knows what the quantum event will be but in another he would also have to wait until the event actually happened first before he could know it becasue the event is uncertain until the very moment it IS.
