No, they don't disprove it. However the Alcubierre metric, which underlies the warp drive stuff, requires something people refer to as 'exotic matter' which in this case means matter with negative energy density. Such matter violates many assumptions, and would normally be considered not to be possible (indeed my memory of Alcubierre's original paper is ...

There's a close representative of exotic matter that IS real. It's the region of pseudo-negative-pressure density that's produced by the Casimir effect. As for negative matter, its expected behaviour is assumed by many to violate mainstream physics. But the behaviour of negative mass - despite being inconsistent with the expected behavior of "normal" ...

Alcubierre [1] and others have shown how a suitable shaping of space-time curvature can be used to generate a warp bubble, where the contents of the bubble can be transported to arbitrarily large speeds, even exceeding the local speed of light, without suffering inertial effects. This can be called an inertialess warp drive. “Abstract: It is shown how, ...
