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…
The Power Spectrum of Cosmological Number Densities
Amanda R. Lopes, Marcelo B. Ribeiro, William R. Stoeger
We study the cosmological power spectra (PS) of the differential and integral galaxy volume number densities and , constructed with the cosmological distances …
Bianchi VI0 viscous fluid cosmology with magnetic field
Marcelo Byrro Ribeiro, Abhik Kumar Sanyal
A spatially homogeneous Bianchi type VI0 model containing a viscous fluid in the presence of an axial magnetic field has been studied. A barotropic equation of state together with…
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…
