Ok, so I got to this question after watching rocket launches on the old youbletuble.. don't judge me, I know it's a Friday and I should be doing that social thing I hear so much about... Anyhow, impulse I get, thrust = movement/g-force, etc., requiring inertial dampers. But warp, based on the contraction and expansion of space in front and behind a ship means no thrust/movement/accelleration and therefore no inertia? So two questions beg, does contraction/expansion in warp still result in acceleration/g-force whether it's moving around you or you're moving through it (yep I get it's all relative!), and if there's actually no 'technical' movement then why do ships generally accelerate to impulse before engaging the warp drive (besides the obvious running away from bad man with the guns), as if it's a pre-cursive requirement to get to a speed that relies on a lack of movement...? Do I remember rightly that in VOY there was an episode where they created a low-level warp field? Also DS9 Emisary, again with the subspace field to reduce mass? Oh, and is a warp field and subspace field the same thing? Weren't they brown in ENT? Ok, that was more like eight questions! J.
