-Poul Anderson, Operation Luna (New York, 2000).
Suppose that there is just a single universe without any branches. In that case, we would still be able to discuss other timelines as logical possibilities even if not as material realities. Thus, if I had attended a different University, then my life would have diverged from that point onwards. Anything might have happened. I would have met different people and would either have married someone else or remained unmarried - or I might have died in a fatal accident on my first day of attendance at a different University.
My question is this. If omniscience were not only possible but actual, would even an omniscient being know what would have happened if I had attended a different University - and if every other such contingency had occurred differently? If every sperm had met a different egg? If the entire world were populated by potential people who were neither conceived nor born in the world as we know it? Or has even omniscience got limits?
