Subject: Re: [FT] Scales
As an excercise, here are some FT scale sweet spots, as long as I didn't make any grade-school math errors, which is always possible: (Abstract 1g to ~10 m/s^2). 1Thrust Min/Turn km/" Genre 1g.05 (3s).05 A 1g.167 (10s).5 B 1g 1 ~20 C 1g 2.5 ~100 D 1g 7.5 ~1000 E 1g ~10 ~2000 F 1g 17 ~5000 G 1g 24 (~25) 10000 H 0.5g.08(5sec) ~.06 B 0.5g 1.5 ~20 C 0.5g 10 ~1000 E 0.5g 34(~35) ~10000 H 1/7g 20 ~1000 E 1/4g 15 ~1000 E 2g 5 ~1000 E Genres (these are taken from my impressions of the various media YMMV), with useful objects for scale: A = "Atmospheric" Dogfighting: Most Cinema/TV Type fighter combat (WWII model?), Babylon 5 = 100" long B = "Newtonian" Dogfighting: (Also possibly more like modern atmospheric?) Babylon 5 = 10" long (Was it 5 miles or 5 km?), Eros = 66"x26", Comet nucleii inches to tens of inches across C = "Cinematic" Cinema/TV scale: Star Wars Capitals (Death Star =~Mimas = 20"), Eros = 1.5"x1", Mathilde = 3", Vesta=25" D = "Hard" Cinema/TV scale: Babylon 5, BSG capitals (Death Star =~Ceres = 9") E = Terrestrial Planet scale: Ceres =~ 1", Earth = ~12", Jupiter atmosphere = "wall" off one side). F = Large Planet scale: Earth ~ 6" Mars ~3" G = Planet System scale:Earth = 2.5" Jupiter = 28" Earth-Moon may be on opposite ends of a large field (75" apart), though the moon would be 2/3" or so across H = SFB/Old Trek scale: Earth ~1-1.5", Earth-Moon=38" , Jupiter=14", Galilean satellite orbits at ~40", 63", 105", and 182"from center of planet (the sats themselves are all rather less than 1" across), Saturn=12", rings extend 1"-82" from "surface", Comet comas tens of inches across. I prefer gaming in the "Terrestrial Planet" scale (and 1g or 0.5g/thrust), but I can see some interesting scenarios with "Planet System" scale, and indeed, most of the others.
