Tau Cetians contains "9": dunno. 9 has only shown up in planet names so far. Temperature of the homeworld: Recall that we've been given the temperature of the homeworld before; it's 4392. That is approximately the average of the center- and ring-temperatures given here. They may just count the average temperature of the planet-ring system as the temperature of the planet. In message 3, planets seemed to be divided into zyz and wyw. We now think that means fluid (gas-giant) planets and inhabitable planets. But planet two is a wyw even though it contains life. Maybe they discovered life there after the terms were invented? Slight nit with Michael's translation of the fluids thing: it should say "liquids are not gases; fluids are the opposite of solids." Different predicates are used. It further supports the idea that "z" is "fluid". Also, you borfled a "false" for a "true". It *is* true that solids are a part of wyw. For the end, I have no clue either. Hmm, maybe I do. What if "-" is an action modifier, like "ing"? Then "2", home, becomes the predicate "-2-", living, and we have "Tau Cetians live on Homeworld." This is compatible with message 7; we have "1, 2, 3... is adding; 'X=1' is equating". But I don't know what "-m-" is. "Existing"? "Acting"? A generic verb which everything performs by definition?
