Matching the Alcubierre and Minkowski spacetimes
Osvaldo L. Santos-Pereira, Everton M. C. Abreu, Marcelo B. Ribeiro
This work analyzes the Darmois junction conditions matching an interior Alcubierre warp drive spacetime to an exterior Minkowski geometry. The joining hypersurface requires that th…
Shift vector sign reversal in the Alcubierre warp drive spacetime geometry and nonlinear Burgers-type dynamics
Osvaldo L. Santos-Pereira, Everton M. C. Abreu, Marcelo B. Ribeiro
This work investigates a sign reversal of the shift vector in the Alcubierre Warp Drive geometry and its effect on the nonlinear reduced structure of the Einstein equations. Previo…
The Warp Drive: Superluminal Travel within General Relativity
Osvaldo L. Santos-Pereira
In 1994, Miguel Alcubierre proposed that the well-known special relativistic limitation that particles cannot travel with velocities higher than light speed can be bypassed when su…
Warp drive dynamic solutions considering different fluid sources
Osvaldo L. Santos-Pereira, Everton M. C. Abreu, Marcelo B. Ribeiro
Alcubierre proposed in 1994 that the well known special relativistic limitation that particles cannot travel with velocities bigger than the light speed can be bypassed when such t…
Perfect fluid warp drive solutions with the cosmological constant
Osvaldo L. Santos-Pereira, Everton M. C. Abreu, Marcelo B. Ribeiro
The Alcubierre metric describes a spacetime geometry that allows a massive particle inside a spacetime distortion, called warp bubble, to travel with superluminal global velocities…
Charged dust solutions for the warp drive spacetime
Osvaldo L. Santos-Pereira, Everton M. C. Abreu, Marcelo B. Ribeiro
The Alcubierre warp drive metric is a spacetime construction where a massive particle located inside a spacetime distortion, called warp bubble, travels at velocities arbitrarily h…
Fluid dynamics in the warp drive spacetime geometry
Osvaldo L. Santos-Pereira, Everton M. C. Abreu, Marcelo B. Ribeiro
The Alcubierre warp drive metric is a spacetime geometry featuring a spacetime distortion, called warp bubble, where a massive particle inside it acquires global superluminal veloc…
