  It is known for a long time that the space time around a spinning cylindrical
symmetric compact object such as the cosmic string, show un-physical behavior,
i.e., they would possess closed time like curves (CTC). This controversy with
Hawking's chronology protection conjecture is unpleasant but can be understood
if one solves the coupled scalar-gauge field equations and the matching
conditions at the core of the string. A new interior numerical solution is
found of a self gravitating spinning cosmic string with a U(1) scalar gauge
field and the matching on the exterior space time is revealed. It is
conjectured that the experience of CTC's close to the core of the string is
exceedingly unlikely. It occurs when the causality breaking boundary, $r_\mu$,
approaches the boundary of the cosmic string, $r_{CS}$. Then the metric
components become singular and the proper time on the core of the string stops
flowing. Further, we expect that the angular momentum $J$ will decrease due to
the emission of gravitational energy triggered by the scalar perturbations.
When a complete loop is taken around the string, the interior time jumps by a
factor $2\pi J$. The proper time it takes to make a complete loop becomes
infinite and will be equal to the period that $g_{\varphi\varphi}$ remains
positive. In this time interval the angular momentum will be reduced to zero by
emission of wave energy. The physical situation of an observer who experience
$r_{\mu}\rightarrow r_{CS}$ is very unpleasant: the energy-momentum tensor
components diverge.
