Hi again! I have some ideas how they form words out of roots. First a list of words we already know from the first five messages: w living z non-living ~ small 1 big 11 the biggest 2 is the name of their home planet In the sixth message 7 is defined as "big speed" and 8 as "small speed" (G7P1$1P7G and G8P~$~P8G), giving: 7 fast 8 slow 4 and x are counterparts, perhaps x inner side/center 4 outer side/peripheral because the name of Tau Ceti is xzx meaning "the non-living center" and the 2 outermost planets have 4 in their names. When I consider y as "general celestial object" the planet names and classes can be translated as follows: xzx Tau Ceti "non-living center" wyw their home "living celestial object" zyz medium sized planets "non-living celestial object" 1y1 big planets "big celestial object" Names contain the additional symbols 9 and 3. I have no idea about 9, but 3 coud be "undetermined". The last sentence will then say "universe is undetermined (yet)". The names are: 2 first orbit 797 second orbit "fast 9" 898 third orbit "slow 9" 323 fourth orbit "undetermined home" 434 fifth orbit "undetermined outer" 4y4 sixth orbit "outer celestial object" The names are possibly given in the early times of astronomical research. They thought perhaps, that 323 also contained life (like we thought about Mars). 434 was the perhaps the outermost known planet. "fast 9" and "slow 9" may be derived from observation, that an inner planet has a higher velocity than outer ones. Thus 797 is the fastest object on a taucetian sky. (9=moving object on the sky?). -Derik.
