Hmm, you seem to wedge in general on paradoxes involving very large numbers times very small ones.
I know that my own heuristic is simply to refuse to multiply with very small numbers. This prunes the paradoxes but has obvious disadvantages. The counters "but, number of fundamental particles in universe" and "but, other daft things with similar small probabilities" feel like cop-outs.
Do you always refuse to multiply by small numbers, or only in certain situations? What do you do instead, then? How do you do your physics homework?
So I'd intended this story as a bit of utterly deranged fun, but it got out of control and ended up as a deep philosophical exploration, and now those of you who care will have to wade through the insanity. I'm sorry. I just can't seem to help myself.
I know that writing crossover fanfiction is considered one of the lower levels to which an author can sink. Alas, I've always been a sucker for audacity, and I am the sort of person who couldn't resist trying to top the entire... but never mind, you can see for yourself.
