Hi Metric, thanks for this question. I can’t wait to hear knowing peoples responses. I’m guessing that the side with the most particles wins out. Also, I’m wondering about the anti - matter issue. If the laws of thermodynamics are reversed in both sides of the spaceship, are you sure that matter is not also reversed? Or that there is no anti- matter?

Sorry man, I got all my physics from Star Trek.

Yes, there is a way in which anti-matter is related to ordinary matter through time reversal, which is why I mentiond that little proviso. But that is seperate from thermodynamics -- you could have a planet made of anti-matter and thermodynamics could work just the same as it does here (and antimatter doesn't violate the 2nd law in particle colliders, for example). Likewise, you could have the situation I describe -- a collection of ordinary matter for whom the thermodynamic arrow of time is reversed.
