Bulk-induced gravitational waves on braneworld wormhole

Gravitational waves result from various spacetime-perturbing events which are due to various kinds of motions and changing distributions of mass. Most studies on the source of gravitational waves were derived from the dynamic character of two binary compacted massive objects such as black holes and neutron stars, therefore gravitational waves which originated from a single event source would be of interest. In this paper, we derive the stress–energy tensor (SET) of a braneworld wormhole and demonstrate how the bulk-induced gravitational waves influence the SET of the wormhole. Thus, this study not only suggests a single source of gravitational waves, but also proves the existence of higher dimensional space by providing a formulation, namely, the SET at the wormhole throat affected by the bulk-induced gravitational waves.
