Did it happen?Posted by: Mathgeekjoe
Let say there was an event that was so small that its effects get overwhelmed by quantum noise. Even with a complete knowledge of the present, it would be impossible to know if the event happen. In fact calculations would consider it highly unlikely that it happened. Did this event definitely happen?
No, the event did not definitely happen. The past doesn't exist, but the present does. If the effects of the past does not definitely prove its existence, then it did not definitely happen.
Yes. The event definitely happened. If you were to go back in time, you would see that it happened.
Without proof, no certainty can be found.
You said so yourself.
Since the narrator is omniscient, I guess we can trust him.
Yes, countless events happen all the time that there are no witnesses to. That no one saw does not nullify the event, even if there is no evidence. It's the counter-point to "perception is reality". Simply because you did not perceive it does not make it less real, and simply because you witnessed it does not mean that it was real in the manner in which you perceived it.
