  • Okay cool, I didn’t put that together while reading the first post. Although my understanding is that Trek warp drives would fall into the Void Drive category based on these descriptions. The bubble completely encases the ship while at warp and effectively shortens the world line they’re following, at least from the ship’s perspective. In the famous “Neelix almost kills the ship with cheese episode” they create a “static” warp bubble and invert it towards the ship in order to heat up all of the biogel packs on Voyager. Also I looked up the impulse engine thing and they arent relativistic but they are capable of accelerating a ship to 1/4C which is surely enough to cause some time dilation issues.


  • For example, impulse engines can not accelerate a ship to anywhere near the speed of light. But they can accelerate it to enough of a fraction of C that things like time dilation become problematic. No breaking of physics but surprise surprise now your crew is 3 minutes younger than they should be, relative to Earth. Add that up over time and you’d potentially have to start swapping out crew members so that they don’t end up younger than their children when they retire. The Star Trek Voyager Technical Manual lists “full impulse” as 1/4C, or nearly 75,000 kilometers per second, which is probably why you hardly ever see it in use unless it’s a life or death situation.





  • You all are mixing your metaphors a bit. Wormholes “fold” space; imagine if the universe was a piece of paper. Now fold the paper in half and poke a pencil through it. That’s folding. “Warp” engines, like the Alcubierre Drive, do just what they say - they warp spacetime itself around the ship by compressing the spacetime behind the ship and expanding the spacetime in front of the ship, essentially creating a pressure differential that naturally pulls the ship along it’s new modified world line. This is what they’re talking about any time you hear them mention a “warp bubble”.
