Novel Realizations of Warp Drive Spacetimes as Solutions of General Relativity
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.
