Noncommutative and Quantum Gravity Theories

It is shown that if a space-time has an isometry group whose Killing vector is time-like in a region V and if there exists one closed time-like curve somewhere in the space-time, then under suitable conditions on V (including the absence of horizons) there is a closed time-like curve through every point of the space-time.
