Superluminal Geometrodynamics of Braneworld Hyperdrive via Brane-Bulk Interaction

Abstract

Alcubierre warp-drive was first to introduce superluminal travel from different approach. Instead of creating short cut through spacetime via a wormhole, geometrodynamics of simultaneously contract and expand spacetime were conjectured. However, both methods require exotic matter that violate energy condition. In this paper we employ the concept of braneworld that naturally influence spacetime geometrodynamics. Start from define and develop the spacetime metric of braneworld warp bubble, the expression for energy densities as function of relevant parameters which contribute to the braneworld approach of superluminal travel by hyperspace-drive were derive
