Lol thank you for the tl;dr
This is some r/saved you a click energy.

Any headline that ends in a question mark can be answered by the word no.
Nice
Article and TLDR are outdated. A solution that doesn’t require negative energy was found in 2021
Energy requirement is still astronomical and we still don’t have any idea how to actually accomplish it, but we are back in the realm of: maybe eventually
The 2021 result is interesting, but:
There is still some debate about whether warp bubbles really can do without negative energy. Recently, three theoreticians suggested that this claim was only true for observers moving next to the bubble. Plus, not everything that seems possible according to the theory of relativity actually exists—or is technologically feasible. For example, Einstein’s field equations can also be used to justify “white” holes (the antithesis of their black hole counterparts), Einstein-Rosen bridges (frequently called wormholes) and other exotic alterations in spacetime that no one has ever observed. That could be because laws of nature, as yet unknown, preclude such phenomena.

Regarding that last one, wasn’t there a finding reciently that Einstein-Rosen bridges and quantium teleportation are in some sense the same thing? I admit most of that news went over my head so I might have misunderstood.
