An accelerating positive-energy warp drive is constructed by matching a flat cavity to a Kinnersley photon rocket, obeying the derived control law −ṁ ≥ 3m|a| and needing no exotic matter.
New realizations of warp drive spacetimes are constructed as solutions of Einstein's equations via geodesic assumptions and relativistic Lagrangian perturbations, revealing coordinate instabilities and a direct link to cosmological models.
Source-consistent warp shells fail energy conditions at the source-vacuum boundary in all examined constructions and parameter scans.
