I've been trying to come up with other examples. One interesting situation I thought of involves Fahrenheit 451. Would it still exist in Thursday Next's version of Earth? After all, our version of Ray Bradbury wrote it in response to his observation that people were becoming less attentive and thoughtful, surely not a danger in Next's book-obsessed culture. So would the Nextian Bradbury still write it at all? Would it come about as alternate history horror, instead of the speculative science fiction it was in our world?

I don't know if such alternate publications would be useful to the PPC, but it could be fun to rewrite a short section of such a book to see what it might look like!

Current Multiverse Theory would say that, under the so-called Compromise Theory, the real Star Trek universe has, by way of Abstract Canonical Entanglement, created* versions of itself which are linked to World One, the Whoniverse, and so on.

*The Division of Applied-and-theoretical Multiversal Physics would like to make it clear that universes are not considered sentient under most versions of Multiverse Theory.

But... until a Doctor Who episode features Star Trek fanfic (which would be hilarious), I'm not sure they need to worry about it? There's no application of the theory, and the PPC is all about applications.
