The unphysical nature of "Warp Drive"
read the original abstract
We will apply the quantum inequality type restrictions to Alcubierre's warp drive metric on a scale in which a local region of spacetime can be considered ``flat''. These are inequalities that restrict the magnitude and extent of the negative energy which is needed to form the warp drive metric. From this we are able to place limits on the parameters of the ``Warp Bubble''. It will be shown that the bubble wall thickness is on the order of only a few hundred Planck lengths. Then we will show that the total integrated energy density needed to maintain the warp metric with such thin walls is physically unattainable.

Steering a warp drive without exotic matter
A positive-energy spacetime for steering a warp drive is constructed by matching an exact Kinnersley photon rocket exterior to a flat interior through a timelike shell that satisfies the dominant energy condition unde...

Steering a warp drive without exotic matter
A positive-energy steerable warp drive is constructed by matching the Kinnersley photon rocket to a flat passenger worldtube, with acceleration controlled by Bondi mass loss obeying a closed-form law.

Observer-robust energy condition verification for warp drive spacetimes
Warpax toolkit demonstrates that observer-robust optimization finds more extensive and severe energy-condition violations in warp drive metrics than single-frame Eulerian analysis.
