wow, that's a great article, it contains some ideas to play with. It doesn't say anything about the teraformers though. I wonder if they are able to compensate for some of those factors. I had wondered about what happened in 2010 where Jupiter became a small sun so many of Jupiters moons became like planets of a smaller sun. Thanks! I was at another forum and nobody wanted to even think about this stuff, like it was a wet blanket to their space party. Oooh how about portable suns, like portable hearters. But if they could do that then they could probably leave the solar system. I wonder if the humans spent several generations aboard the ships that left earth or if they do have inter-stellar travel but only the most rich and powerful have access. My dream show has Joss doing plot and characters but a star trek team covering speculative science. I used to love on TNG when I woud ask but wouldn't that? . . . and the next scene would answer my question.
