a few weeks ago i got it into my head i wanted to run a hard sci-fi tabletop RPG, nominally set in the Metroid universe.
I decided that i wanted to use Jump drives as my primary FTL travel. It would be instantaneous and relatively safe, provided it was far enough away from a solar mass. my notes give about 75+AU from Sol for 99.9998% success rate, and 50% success rate at about 60 AU, declining extremely rapidly from there.
I need to come up with a believable rate of travel to get from one point in a star system to a jump point. I want the travel time to be about 10-14 days, and the maximum allowed speed to be about .3c. travelling 1AU @ .3c takes approximately half an hour. I plan on using an inertial dampener device to allow for reasonably swift acceleration (at least that's what i think that device would do). what sort of relativistic effects can I expect when travelling at .3c?
Interstellar communication is handled by comm arrays and comm buoys that bounce via jump drive from array to array transmitting data. I haven't figured out a reasonable amount of time for a buoy to make a circuit, or how many planets a circuit would entail. it takes light about 50 hours to travel 75 AU (give or take) where these comm arrays would likely hang out so figure a buoy takes 25 hours to make a round trip. meaning that a message takes about six days to go from one place to another at an average extreme.
I'm most curious about reasonable acceleration for spacecraft, and relativistic effects at .3c. i can say that the inertial drives mitigate relativistic effects, because i just don't want to deal with them as a game master, and it would be sweet if i could just have a decent reason to magick them away.
