I do not understand how the proposed warp drive could help with moving a ship. It sounds more like a "time dilation device" to shorten the travel time for the crew than a setup to make moving through space actually easier.
Would you mind explaining?
- nynx 5y agoA conclusion of this paper is that a warp bubble that fits into the categories described requires external propulsion. I agree, the positive energy, spherically symmetric warp bubble isn't particularly interesting and certainly not a new effect.
- threesongs 5y agoA conclusion of the paper is that any warp drive, including all the ones proposed in the literature, fits in the categories explained in the paper.
- abobrick 5y agoI believe spherically symmetric bubbles in subluminal regime are more interesting than any warp drive solutions suggested so far. Firstly, they do not require negative energy. Secondly, the passengers in such bubbles age less by the time they reach any destination compared to other warp drives or conventional rockets. Given that exceeding the speed of light is fundamentally prohibited by physics, I would say that spherically symmetric warp drives are the most interesting warp drive constructions we got so far.
