I want some Dedicated sci-fi fans to help me design a complete space-faring Universe from the ground up to prove that sci-fi can be done right. There have been several recent threads remarking on the failing points of current sci-fi and more comments made about poor writing than can be ignored. This is your oppertunity to put your mind where your complaints are. To start off we'll have to make some limited concessions to the sci-fi genre at large: To cover the need for interstella transport and communication we will use a space folding widget similar to the Babylon 5 stargate system. Lynchpins: -there is no communications in null space. The craft has isolated itself in an artificial bubble of unique spacetime for the duration of the fold. -Only Capital Ships have enough power and mass to maintain their own fold drives and null-space pocket generators. -Popping into null-space as a defensive maneuver is risky because you need to designate not only x/y/z coordinates for where you pop back into realspace but also a time coordinate. popping back into realspace with your exit point equal to your entrance point results in a paradox-induced explosion. -Folding space near stars in a pain in the ass even for Capital ships because Spacetime is "thicker" in stellar space. -Particularly advanced races may be experimenting with "Stellar folding" where a Capital ship tunes and presets it's fold drive to use a star's centerpoint as a fold-gate. This is a VERY risky maneuver and the exit point is always the center of another stellar mass so knowing where the "out" is is essential! Now that we have travel and communications outlined let's look at biology: - Giant-insect species would have to be aquatic or low-gee.... period. - Sentient species are confined to environments where adversity and stability have conspired to create them. - Water and free-carbon are prerequisites to life. -Aquatic species will be quite likely. - Species that use technology will most likely not use the same RF range for the same things to begin with. - Species with vastly differing native environments will have vastly differing cultures and environmental needs. - Common means of communication are reliant on a common medium and similar ancestry. Aquatic species are more likely to use sound or chemical communication than visual communication. Also: Sound through air is very different than sound through water.
