Wormholes in vacuum Brans-Dicke theory
Abstract
It is shown that among the different classes of claimed static wormhole solutions of the vacuum Brans-Dicke theory only Brans Class I solution with coupling constant ω less than -1.5 (excluding the point ω =2) gives rise to physically viable traversable wormhole geometry. Usability of this wormhole geometry for interstellar travel has been examined.
