1. Do unicorns exist on other worlds?
What kind of crazy question is this? Unicorns don't exist at all (S)
Maybe. Depends on what is meant by existence and worlds (N)
2A.) (if S) Would you go to a party on a unicorn-inhabited planet if it existed?
These unicorn questions are a waste of time (J)
Heck yes! (P)
2B.) (if N) Would unicorns make the world a better place?
No, the existence of them would make them yet another animal to hunt and exploit (F).
That's irrelevant, we can devise unicorn robots now (T).
