Friction from the interstellar medium does become a concern when you get into the vicinity of ~ .99 of c, depending on the density of the medium through which you are traveling. But other than that yes.

I'm not aware of any remotely reasonable FTL mechanism proposed that actually involves g-forces in the direction of travel. Most tricks involve moving the space around something, moving it out of the way, bringing two points in spacetime closer, etc.

Though one thing I've been trying to puzzle over is how to handle gravitational fields passing through a wormhole, which seems to present a long term problem for a wormhole network.

I haven't read the whole thread, so this may have been already pointed out, but if someone were using "warp bubble" warp drive, technically, they wouldn't really be moving. It's the space around them that would be moving. So they shouldn't feel any G forces, right? Did I get this totally wrong?

Please explain "they wouldn't really be moving". Note that there is no absolute reference frame.

He should have said "they don't experience any g-force".

Batman is about to talk about something he really doesn't know beans about alert-
I think the' they wouldn't really be moving' comment refers to ships with the kind of stardrive that has them not moving WRT the spacetime immediately surrounding them, but instead taking that bubble of spacetime along with them, so whileoverall the ship is moving FTL, WRT local spacetime it's sitting still.
