COSMIC SPINNING STRING AND CAUSAL PROTECTING CAPSULES

A method by which a geometry with causality violation can be taken as a part of a globally causal space-time model is presented. This proced ure is applied to a pair of extensions to Godel's space-time: a ''Gode l-generalized'' and a stringlike solution. The latter is shown to be a n intermediate region between Godel and deformed Minkowski geometries. Some conclusions and general ideas concerning structures with closed timelike curves are also presented.
