I thought the Enterprise was stationary inside a moving warp bubble.
Just saw the new Star Trek movie - thought it was pretty good, really like the guy that plays young Spock. Obvious that they will have more with the same cast following this one.
It is..sort of. The warp drive forms the warp bubble around the nacelles radiating outward, then the impulse drive pushes the ship forward in the bubble. Before it can hit the front of the bubble, the warp drive reforms the bubble.
All this may have changed because the series Enterprise changed some canon and the new movie looks like it rewrites the whole story from scratch. I stopped being an “official” Trekkie when someone decided that “Trekkie” isn’t cool and “Trekker” is. (Either one marks you as a nerd, so what’s the difference? Revel in your nerd-dom, Trekkies and Trekkers!)
