In this work, behaviour and main properties of Gödel and Gödel-like solutions, which describe homogenous and stationary space-times with rotation, in the gravitational Brans-Dicke formalism, which is one of the first and best known scalar-tensor theory, built up for being totally compatible with Mach’s principle and containing General Relativity as a limit case, are studied and discussed. Essential theory and concepts are reviewed and applied, analyzing their consequences. This way, special attention is paid on the consistency and correspondence of the resulting field equations, the role of cosmological constant and Mach’s principle in the compatibility of the solutions, as well as the possibilities for avoiding the associated causality violation of this kind of solutions whit cosmic rotation.
