Link to one of the referred papers « Introducing Physical Warp Drives» https://arxiv.org/abs/2102.06824

That one, at least, doesn't claim to allow faster than light travel using known physics: "We show that a class of subluminal, spherically symmetric warp drive spacetimes, at least in principle, can be constructed based on the physical principles known to humanity today." (emphasis added)

Super helpful tip. Wishing I knew about this years ago!

Thanks for pointing Dali out. I just added it to the list of choices.
