Warp Drives are in principal possible The key idea is to contract space-time in front of you and to expand it behind The Alcubierre Metric does just this, and is consistent with Einstein's Theory of General Relativitypic.twitter.com/vQuzMH6Him

the problem is that we don't know how to artificially create the necessary curvature without huge masses .. that is, we don't know how to make artificial gravity .. yet

When it's said that a "warp drive solution requires negative density (NED)", does that mean: 1) This particular warp drive solution requires NED, but other ones might not if they exist Or:

good question .. i believe all models of the warp drive suffer from a similar issue

Also, this show-stopping problem: "Unfortunately, even for very short journeys the energy released is so large that you would completely obliterate anything in front of you.” https://phys.org/news/2012-03-warp-killer-downside.html …
