In this paper the problem of the quantum stability of the two-dimensional warp drive spacetime moving with an apparent faster than light velocity is considered. We regard as a maximum extension beyond the event horizon of that spacetime its embedding in a three-dimensional Minkowskian space with the topology of the corresponding Misner space. It is obtained that the interior of the spaceship bubble becomes then a multiply connected nonchronal region with closed spacelike curves and that the… 
Warp Drive Basics
“Warp drive” spacetimes and wormhole geometries are useful as “gedanken-experiments” that force us to confront the foundations of general relativity, and among other issues, to precisely formulate
Quantum tunneling and quasinormal modes in the spacetime of the Alcubierre warp drive
In a seminal paper, Alcubierre showed that Einstein’s theory of general relativity appears to allow a super-luminal motion. In the present study, we use a recent eternal-warp-drive solution found by
Quantum effects in warp drives
Warp drives are interesting configurations that, at least theoretically, provide a way to travel at superluminal speed. Unfortunately, several issues seem to forbid their realization. First, a huge
Fundamental limitations on ‘warp drive’ spacetimes
‘Warp drive’ spacetimes are useful as ‘gedanken-experiments’ that force us to confront the foundations of general relativity, and among other things, to precisely formulate the notion of
An Assessment of Faster-Than-Light Spacetimes: Make or Break Issues
*Implementation of faster-than-light (FTL) interstellar travel via traversable wormholes, warp drives, or other spacetime modification schemes generally requires the engineering of spacetime into
Traversable acausal retrograde domains in spacetime
In this paper we present geometry which has been designed to fit a layperson’s description of a ‘time machine’. It is a box which allows those within it to travel backwards and forwards through time
Conformal Gravity and the Alcubierre Warp Drive Metric
TLDR
If conformal gravity is a correct extension of general relativity, superluminal motion via an Alcubierre metric might be a realistic solution, thus allowing faster-than-light interstellar travel.
Description of the Motion of Objects with Sub- and Superluminal Speeds
In this paper a direct derivation of the dynamics of objects moving with relativistic speeds is presented, based on two assumptions: (i) energy and mass of an object in motion are equivalent
