We use the term possible to often refer to events that don’t violate a certain model of reality and impossible to refer to events that do. A human being having ten fingers vs. a human being with five heads.
But the series of events in the world clearly seem to be a single chain. And in this chain, events happen or don’t happen. Of course, there are other universes and worlds postulated, but those haven’t been demonstrated. And even if they did exist, events may be single chains in those universes as well (although I believe there is a certain interpretation in QM where all possible events happen).
So what does it mean to say that an event X is possible if X either happens or doesn’t happen? Shouldn’t we instead use the phrases “has happened”, “can’t happen”, or “will happen”? Using the word possible, especially when referring to events in the past, seems to imply the world could have turned out a different way from the current status quo. But despite whatever you believe in, there is clearly no way to rewind the past, so I fail to see how you can possibly have evidence for this.
Is this yet another term, that despise its supposed usefulness, does not have any basis in reality?
