entr0py says... I'm just barely geeky enough to find this interesting, but here goes. The first reason is that logarithmic scales show up in science all the time, and are frequently misunderstood by layman and media, they just aren't at all intuitive. The second is that those shows were written over decades by smart science-literate people who put in all of these careful details that totally flew over my head, it's fun to look back and see it was deeper than I knew at the time. When Sci-fi is written with a good understanding of science and physics, it makes the fantastic parts seem more plausible because the rest checks out. The alternative way to do Sci-fi is to just say "Screw it, it's all magic!". Which works for Star Wars but isn't compelling in the same way. cloudballoon said: What's so intriguing about made up numbers though?
