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…
Galaxy Mergers in a Fractal Cosmology
Bruno J. Souza, Osvaldo L. Santos-Pereira, Marcelo B. Ribeiro
This work discusses the influence of galaxy mergers in the evolution of a parabolic Lema\^ıtre-Tolman-Bondi (LTB) cosmology with simultaneous big bang endowed with two consecutive…
