Redshift drift is the phenomenon whereby the observed redshift between an emitter and observer comoving with the Hubble flow in an expanding FLRW universe will slowly evolve -- on…
ADM mass in warp drive spacetimes
Sebastian Schuster, Jessica Santiago, Matt Visser
What happens when a warp bubble has mass? This seemingly innocent question forces one to carefully formalize exactly what one means by a warp bubble, exactly what one means by havi…
Timelike vs null deceleration parameter in tilted Friedmann universes
