Perfection said:What if the universe has no beginning but a definite end?
For the moment, and with great gnashing of teeth, I begrudgingly

I characterized it like so:
Choice 3 = universe (with time) --> event --> no universe
But I think that is wrong. How about:
Choice 3 = universe (no time) --> event --> no universe
Since prior to our event, there would be no time (no events to begin time)and after the event no universe.
