This isn’t anything new. The Alcubierre Drive has been a concept for quite a while now. I was hoping this article might have been about reducing the theoretical energy requirements again (they’re currently at the mass-energy equivalent of Voyager 2, which is a significant step down from Jupiter, the Sun, and the entire universe) but it just retreads what’s already been mentioned before.

One thing the article forgot to mention is how it doesn’t violate general relativity or causality because the ship itself doesn’t actually physically accelerate to superluminal speeds, it’s just being carried in a bubble of warped space-time that’s “moving” (or really, warping space around it to change its position) at that speed.
