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.

abstract
It is shown how, within the framework of general relativity and without the introduction of wormholes, it is possible to modify a spacetime in a way that allows a spaceship to travel with an arbitrarily large speed. By a purely local expansion of spacetime behind the spaceship and an opposite contraction in front of it, motion faster than the speed of light as seen by observers outside the disturbed region is possible. The resulting distortion is reminiscent of the ``warp drive'' of science fiction. However, just as it happens with wormholes, exotic matter will be needed in order to generate a distortion of spacetime like the one discussed here.

Preliminary analysis of orbiting spacecraft around a black hole to test the compact object's nature and General Relativity under the assumption of deceleration capability.
Civilizations can achieve galaxy-spanning reach within biological lifetimes via time-dilated orbits near black hole photon spheres using classical general relativity, with a Type II civilization enabling 10^4 dilation factors.
