For those of you that don't know latin, Terra means Earth and is probably what our system would be named if we ever go interstellar. I've recenty read a novel* that describes Atlantis of myth as this giant , zero-point-energy-powered machine that was built by our ancestors to protect our planet from gravity waves. It puts the date of construction of this machine at 12,000 years ago or so, and the machine is built out of a carbon-60 ("buckyball") alloy. Taking this further, if such technology existed, then our fictional ancestors could have had some form of interstellar transport and some of them would have opted for leaving Earth and chancing it out in the galaxy, instead of pouring all resources into a machine that might not have worked. (note: all fictional!) Which brings me to my second point. The map of the galaxy in NJO books has an entire quarter of the galaxy listed as '"Unknown Regions". Humans widely populate the Republic/Empire regions, but no home planet has been named. taking into consideration my previous paragraph, could the Terran system, the home planet of humans, be lurking in the Unknown Regions? And, as NR forces are pushed further back into these Regions, would they eventually discover Earth? *Stel Pavlou, "Decipher". Harper Collins, 2002.
